1, the definition of digital pressure detection instrument
The digital pressure detection instrument is an instrument that measures the physical pressure signal. The pressure measurement converts the physical signal collected by the sensor into an electrical signal, and then amplifies and filters the output signal of the pressure sensor through an external circuit. The /D converter converts to a digital signal that is processed by the microprocessor to implement the pressure measurement function. There are two main application methods for digital pressure detection instruments. They are direct pressure measurement and comparison verification between pressure instruments. Direct pressure measurement mainly refers to the on-site pressure measurement of pipelines and pressure vessels; pressure calibration refers to evaluating the value indicated by a pressure meter or measurement system under the specified conditions by the corresponding pressure standard to reproduce the measured values. A pressure reference standard is used to assign values ​​to the pressure instrumentation and the pressure instrumentation values ​​are traced back to the values ​​reproduced by the pressure reference standard.
2, digital pressure detection instrumentation application
Digital pressure detection instrumentation mainly meets two applications: First, it is used to measure the pressure of fluid in pressure vessels and pipelines. It is mainly used in industrial production to measure the pressure of various gas and liquid media in pipelines. The measurement and control of the fluid pressure realizes the control of product, production, and on-site safety. The second is the verification of the pressure measurement instrument itself and the accuracy of the instrument. It is an important index that is effectively achieved by the above-mentioned purpose. In digital pressure detection instrumentation, high-precision meter accuracy can be two to four times as accurate as low-precision meters, and high-precision meters can be used to verify low-precision meters.
The digital pressure detection instrumentation industry is an industry that provides measurement and inspection methods, methods, and control systems for modern society's production, life, and military fields. Digital pressure detection instruments and meters enable scientific and quantitative measurement in all areas of our production and life. The necessary means to achieve scientific understanding in the economic field.
Second, the digital pressure detection instrumentation market capacity and trend analysis
In the past two years, China's digital pressure detection instrumentation market has maintained a rapid growth rate. In 2009, the digital pressure detection instrumentation market capacity was 2.201 billion yuan. In 2010, with the rapid growth of GDP, the digital pressure detection instrumentation market capacity reached 24.94. Billion, although the growth rate of petroleum, chemical industry, electric power, and metallurgical industries has slowed down in the next few years, on the basis of the continuous increase of China’s total economic output, the industries mentioned above will still maintain a stable growth of a certain extent, which will affect the future. The market demand for digital pressure testing instruments and meters will continue to grow steadily. It is estimated that the market capacity of digital pressure testing instrumentation in China between 2011 and 2015 will be 2.736 billion yuan, 29.97, 32.92, 36.13, and 4.029 billion yuan, respectively, for 2009-2015. The compound growth rate exceeds 10%. The specific conditions of the industry are as follows:
1, metallurgy
Steel
At the end of 2010, China's crude steel production reached 627 million tons, a record high, and sales profit margin fell from more than 8% in the end of the “fifteen†period to less than 3%. High output and drastically reduced profit margins have forced the steel industry to make major adjustments. The main direction of adjustment is to increase efficiency on the basis of controlling the total amount, and China's steel production will basically remain stable in the next few years. In 2011 and the “Twelfth Five-Year Plan,†the relevant policies for the steel industry will mainly follow two main lines. The first is mergers and reorganizations to increase industry concentration. It is expected that China will continue to focus on promoting industry consolidation in the future. The second is energy conservation and emission reduction, and the realization of sustainable development. It is expected that the approval of new production capacity in the future will become more stringent, and the efforts to eliminate backward production capacity will gradually strengthen, mainly adopting measures of differential electricity prices or even power cuts.
Under the above background, the steel industry will not have too high growth rate in the next few years. However, with the macroeconomic fundamentals remaining stable, China's steel industry output and demand will continue to grow in 2011, but the growth rate will decrease. The possibility of sudden changes in the production and operation situation is also less likely. Among them, crude steel production will maintain a modest growth. It is expected that China's crude steel production in 2011 will reach 660 million tons to 670 million tons, which will be lower than the 2010 level. Since the development of China's steel industry will shift from "high-speed extensive" type to "fine deceleration" type, it is expected that the average annual growth rate during the "12th Five-year Plan" period will be about 6%, which is about half that of the "Eleventh Five-Year Plan" period.
Pressure gauges are used in pressure-controlled pipelines at all production stages of iron and steel companies. Pressure instruments used in production sites mainly include two types: one is a transmitter, and the accuracy is a few thousandths, and the second is an ordinary pressure gauge, and the accuracy is 1.0% and 1.5%. These two types of tables require a higher accuracy level of pressure gauges to verify. The accuracy of calibration tables is 0.1% and 0.05%.
A crude steel production of 8.9 million tons of steel mills, equipped with tens of thousands of pressure monitoring points, pressure inspection of these points is generally responsible for the inspection personnel, each inspection personnel is usually responsible for the pressure of hundreds of monitoring points According to the survey, a set of pressure test instruments is used to estimate the number of personnel in each inspection team. The conservative estimate of crude steel production is 850 million tons. The total number of pressure detection instruments to be configured is about 500 sets. Based on this, it is roughly estimated that the digital pressure detection instrumentation market capacity in China's steel industry in 2010 will be approximately 163 million yuan. Due to the impact of China's macro-control on the steel industry during the 12th Five-Year Plan period, the increase in demand for digital pressure instrumentation in China's steel industry from 2011 to 2015 will not be too high. It is expected that the market for digital pressure testing instruments and meters in China's steel industry in 2015 The capacity is about 218 million yuan, and the compound growth rate from 2009 to 2015 is about 7%.
Non-ferrous metals
In 2008, affected by the financial crisis, China's non-ferrous metals and other industries added value slowly. In 2009, supported by the Central Government’s plans for expanding domestic demand and maintaining growth, non-ferrous metals have achieved remarkable results in responding to the international financial crisis. In 2009, China’s output of ten non-ferrous metal products Totally 26,048,800 tons, an increase of 3.99% year-on-year; driven by the demand for investment in fixed assets in 2010, the growth rate of non-ferrous metal production exceeded 20%; in the first few months of 2011, the total output of non-ferrous metals had a larger range than the same period of last year From January to March 2011, the output of ten kinds of non-ferrous metals nationwide was 8.0948 million tons, an increase of 9.28% year-on-year. Although the growth rate has declined, the non-ferrous metal industry remains stable due to the demand.
For a long time, the development of the non-ferrous metals industry in China has been an extensive expansion at the expense of resources. With the rising cost of resources and the sudden increase in environmental pressure, the existing development mode of the non-ferrous metals industry is insufficient to support the sustainable development of the industry. In order to effectively enhance the market competitiveness of the non-ferrous metals industry, strict control over the growth of the industry can, on the one hand, slow down the excess production capacity. On the one hand, it can set aside time to absorb the existing surplus and backward production capacity. Non-ferrous metals will enter the growth period of speed control. The forthcoming "12th Five-Year Plan" for the non-ferrous metals industry will control the production of ten major metals within the annual growth rate of 8%. According to this growth rate, it is expected that China will have Metal production will be around 43.16 million tons.
Based on the output of non-ferrous metals in China, it is roughly estimated that the market capacity of digital pressure detection instruments and meters in China's non-ferrous metals industry in 2010 will be approximately 28 million yuan, which will increase to 0.43 billion yuan by 2015.
2. Oil and gas
Refinery
China's oil refining industry has now entered a new era of historical development. In the future, China's oil refining industry will strive to change its development mode, and through the adjustment of its structure, rational distribution, optimal allocation of resources and markets, the promotion of scientific and technological innovation, and the promotion of integrated refining and chemical and base construction, it will continue to increase its scale strength while continuing to increase its profitability. With international competitiveness, the stable and rapid development of the industry is maintained, and the transformation from a large oil refining country to a powerful oil refining country is truly realized. The steady growth of oil refining capacity and the further development of the diversified competitive landscape in China are a major development trend in the oil refining industry.
In 2010, China will put into operation the Qinzhou refinery in Guangxi and the Huajin refinery in Shenyang. At the same time, some refineries will complete the reconstruction and expansion, adding an additional refining capacity of 30.5 million tons per year. The National Energy Bureau's work conference will plan for China's oil and gas development in the next three years, continue to expand the scale of oil refining and increase the construction of oil and gas production bases so as to achieve the diversification of oil and gas resources acquisition and the scale of oil and gas production capacity. In the next three years, China will start construction of large-scale oil refining projects in Sichuan, Guangzhou, Quanzhou and Shanghai, accelerate the construction of refinery expansion projects in Zhenhai and Maoming, and actively promote large-scale joint ventures such as Venezuela, Qatar and Russia. At the same time, it will continue to stabilize the output of old eastern oilfields such as Songliao and Bohai Bay Basin, accelerate the construction of the western oil and gas areas such as Tarim and Junggar, and increase offshore oil and gas production. It is estimated that by 2011, China will add 40.1 million tons of refining capacity. In the next five years, China's annual refining capacity will increase by 6% to 7%.
A refinery with a capacity of 5 million tons will need to deploy about 2,000 pressure transmitters; a precision pressure gauge with an accuracy of 0.1% or more will be about 3,000, and each unit will cost about 1,000-2,000 yuan; an ordinary pressure gauge will be about 7,000; Need to configure the pressure test list about 540, each unit price of about 20,000 yuan. It can be estimated that the market capacity of digital pressure detection instruments and meters for refineries with a capacity of 5 million tons is about 15.3 million yuan.
gas field
Natural gas is a general term for gas mixtures that are mainly composed of hydrocarbons in underground rock reservoirs. The main component is methane, followed by ethane, propane, and butane. It is a high-quality fuel and chemical raw material. Natural gas is an important energy mineral resource. For its use, it is not only a high-quality energy source but also an important multi-purpose chemical raw material. Natural gas has the advantages of easy extraction, low cost, high recovery, ease of use, and low pollution. Therefore, many countries in the world have accelerated the pace of natural gas exploration and development and utilization. As a result, the energy structure was optimized, energy shortages eased, the development of the natural gas industry was promoted, foreign trade was improved, and good economic and social benefits were achieved. In the past 40 years, especially in the past 10 years, China has attached great importance to the exploration and development of gas fields. Sedimentary rocks in China have a wide distribution area and many continental basins, forming favorable geological conditions for multiple natural gas storages.
In the Sichuan gas field, the Sichuan Basin not only produces oil but also produces natural gas. The Sichuan oil and gas field is mainly produced from natural gas. It is also known as the Sichuan gas field. It is China's largest natural gas field and has built China's largest natural gas industrial base. In the entire Sichuan Basin, natural gas resources are widely distributed. The Sichuan gas field has become a huge gas field system including the eastern, southern Sichuan, southwest Sichuan, and Chuanzhong and Sichuan and northern Sichuan development zones. The gas field in Sichuan Province has a large number of production (reservoir) layers, and its stratigraphic distribution is also very extensive. Sichuan Gas Field is rich in natural gas resources and is one of the largest gas fields in the world with proven reserves of over 100 billion cubic meters. In 1986, China discovered 16 of the larger gas fields with reserves of more than 5 billion cubic meters, mostly in the Sichuan Basin. Among the 16 large gas fields, there are 2 large-scale gas fields with proved reserves of over 30 billion cubic meters, and 6 medium-sized gas fields with proven reserves of over 10 billion cubic meters. Sichuan's natural gas industry has developed rapidly and made great contributions to Sichuan's economic and social development. With the continuous development of China's economy and the continuous increase in the demand for energy and raw materials, the exploration, development and utilization of natural gas in Sichuan gas fields has a very broad prospect.
The Karamay Oil and Gas Field and the Karamay Oil and Gas Field have long been mainly engaged in oil exploration and development. In recent years, the Karamay Oil Field has begun to focus on exploration and development of natural gas resources in its Junggar Basin. In 2006, Karamay Oilfield discovered a Mahe field with a capacity of 30 billion cubic meters. It is currently in operation and can produce 1.3 million cubic meters of natural gas per day. Subsequently, in December 2008, the first-phase construction project of the Karamay Formation in the natural gas field with over 100 billion cubic meters of reserves in the Junggar Basin was completed and put into operation, which enabled the Karamay Oilfield to exceed 10 million cubic meters of natural gas per day. In the Karamay Field, the increase in natural gas production in the Karamay Oilfield on the edge of the Junggar Basin in 2008 hit a record high, and the newly added proven natural gas reserves exceeded the sum of the past 50 years. In accordance with the concept of oil and gas exploration and development, the development of natural gas in the Karamay Oilfield began to increase in recent years, and is progressing from large oil fields to large oil and gas fields. In 2008, Karamay Oilfield produced 3.42 billion cubic meters of natural gas, a net increase of 520 million cubic meters from 2007, the highest increase in history. At the same time, the newly added proven reserves of natural gas totaled 134.8 billion cubic meters, with a predicted reserve of 71.28 billion cubic meters, and the proved reserves exceeded the sum of the past 50 years.
The development of the natural gas industry in China drives the development of digital pressure detection instruments and other industries. The vigorous development of gas fields in China has a large demand for digital pressure detection instruments and meters. Digital pressure detection instruments are mainly used to measure and monitor the pressure of gas field monitoring points. Generally speaking, pressure gauges with an accuracy of 0.2%-0.05% can satisfy the application of gas fields. Taking the gas field with a gas production of 15 billion cubic meters as an example, there are about 3,000 pressure measurement points. According to the specific situation, a variety of pressure gauges will be deployed. Each gauge is equipped with one less pressure gauge, and some more configurations with 5-6 gauge pressure gauges. Each measuring point is equipped with two pressure gauges.
oilfield
In 2009, although crude oil imports have exceeded their own production, China's oilfield production has risen steadily. The following are the top-ranking oil fields and their production.
Daqing Oilfield produced 400.0299 million tons of crude oil and 308.983 million cubic meters of natural gas. Following the steady production of 50 million tons of crude oil for 27 years, it also stabilized production for more than 40 million tons of crude oil for the seventh year, and once again wrote the Chinese crude oil company's annual output of crude oil.
Shengli Oilfield, located in Shandong Province, produced a total of 27.91 million tons of crude oil, maintaining steady growth for 10 consecutive years and maintaining a balance between storage and production for 13 consecutive years.
Changqing Oilfield produced a total of 15.72 million tons of crude oil, 19 billion cubic meters of natural gas, oil and gas equivalents exceeded 30 million tons, becoming the largest increase in domestic output, the fastest growing, the best growing oil and gas fields. At the same time, oil and gas reserves also achieved historical breakthroughs: Proved oil reserves were 265 million tons, natural gas reserves were 215.1 billion cubic meters, and basic proven natural gas reserves were 570 billion cubic meters.
The oil and gas equivalent of Bohai Oilfield exceeds 20 million tons, and the crude oil output is nearly 1 million barrels.

Jilin Oilfield produced 6.05 million tons of crude oil and 6.07 million tons of oil and gas equivalents.
Tarim Oilfield achieved a total production of 5.54 million tons of crude oil, 18.09 billion cubic meters of natural gas, and an equivalent oil and gas output of 20.65 million tons, which will continue to exceed 20 million tons.
In addition, China also has a number of oil fields such as Jianghan Oilfield, Zhongyuan Oilfield, and Yumen Oilfield. Although the output of some of these oil fields is declining, some of the newly discovered oil fields have not yet been mined.
Each oil field has a large number of pressure measurement points, and there is a large amount of pressure calibration requirements. According to the actual situation, each oil field will be equipped with an unequal number of pressure gauges, with an average of 2 pressure gauges per measuring point. A pressure calibration task force is established in each oil production area.
Natural gas transmission
The construction of oil and gas fields places great demands on digital pressure inspection instruments and meters. Tarim-Shanghai gas transmission project in the Yangtze River Delta, construction of natural gas high-pressure and high-yield well facilities, natural gas gathering and boosting stations, natural gas dehydration and dehydrocarbonation stations, and stations containing alcohol, salt, and oily sewage, supporting power supply, water supply, Roads and other facilities, with a total investment of about 20 billion yuan in oil and gas fields with an annual gas production capacity of 12 billion cubic meters and 900,000 tons of condensate, will have about 12% of the investment amount for process inspection and control instruments, and may have 2.4 billion yuan. The scale of demand.
The demand for digital pressure testing instrumentation in natural gas transmission pipelines. The qualified gas from the natural gas processing plant was brought together at the first station of the Lunnan oil and gas field. The pipeline with a diameter of 1118mm was transported at a pressure of 8.4 MPa, passing through 9 provinces, municipalities, and autonomous regions, and finally reached Shanghai. Long-distance pipelines have to pass through many complex areas such as mountains, valleys, rivers, swamps, and saline-alkali lands. The monitoring, control and acquisition of pressure, temperature, flow, and natural gas density in the transportation process require a large number of instruments and meters. The investment in fixed assets for natural gas transmission pipeline construction was 38.4 billion yuan, and investment in process inspection and control instruments accounted for approximately 5%-7% of the investment, with a market demand of about 2 billion yuan.
Downstream market supporting facilities for digital pressure detection instrumentation. The associated construction of market pipeline network and industrial utilization for the downstream market development is approximately 60 billion to 80 billion yuan. The development of the downstream market should be synchronized with the main project of West-East Gas Pipeline. The investment in process inspection and control instruments accounts for approximately 7% of the total investment. ~10%, there may be 4.2 billion market opportunities.
In general, the demand for digital pressure detection instruments and meters for the West-East Gas Pipeline Project is huge. The total investment in the above three areas of process inspection and control instruments is about 8.9 billion yuan, which is calculated according to the ratio of digital pressure detection instrumentation accounting for approximately 5% of the total process inspection and control instrumentation equipment. The total investment is about 445 million yuan. According to the replacement rate of 10% per year in the industry, the annual demand for digital pressure detection instruments and meters for the first phase of the project is about 45 million yuan.
The Demand for Digital Pressure Testing Instruments for the Second West-East Gas Pipeline Project. The West-East Gas Pipeline Second Line Pipeline west from Xinjiang Horgos, after Xi'an, Nanchang, south Guangzhou, east to Shanghai, through Xinjiang, Gansu, Ningxia, Shaanxi, Henan, Anhui, Hubei, Hunan, Jiangxi, Guangxi, Guangdong, Zhejiang and Shanghai 13 provinces, autonomous regions and municipalities. The total length of the trunk line is 4,859 kilometers, plus several branch lines, the total length of the pipeline is more than 7,000 kilometers. According to the demand for digital pressure testing instruments and meters for the first phase of the project, the annual demand for digital pressure detection instruments and meters for the second phase of the project is about 054 million yuan.
West-East Gas Pipeline Project's Demand for Digital Pressure Instrumentation. The trunk pipeline runs from the first station in Horgos, Xinjiang, to the east of Shaoguan, Guangdong Province. From the Horgos-Xi'an section, the second line along the West-East Gas Pipeline runs eastward, passing through 8 provinces and autonomous regions in Xinjiang, Gansu, Ningxia, Shaanxi, Henan, Hubei, Hunan, and Guangdong. The third-phase engineering design has annual gas transmission capacity of 30 billion cubic meters, and the construction period is mainly concentrated in 2010-2014. It is roughly estimated that the digital pressure detection instrumentation to be put into the annual transmission pipeline construction should be over 100 million yuan, taking into account the annual In response to demand changes, the number of digital pressure detection instruments and meters required for the West-East Gas Pipeline Project in the next few years will be between RMB 1-2 billion.
In summary, the demand for digital pressure detection instruments and meters for natural gas transmission is very impressive. In 2011, the market capacity of digital pressure detection instruments and meters was 212 million yuan, reaching 523 million yuan by 2015.
Chemical industry
At present, China has established a complete chemical industry system. The chemical industry includes basic chemical industry and plastics, synthetic fibers, rubber, pharmaceuticals, and dyes industries. Its internal classification is more complex. It mainly divides the chemical industry into two categories: inorganic chemistry and organic chemical industry. The former mainly includes acid, alkali, salt, hydrochloric acid, rare elements, and electrochemical industry; the latter mainly contains synthetic fibers. , plastics, synthetic rubber, fertilizers, pharmaceuticals and other industries.
China's chemical industry started from the beginning of the 19th century and developed rapidly in an industrial sector. The chemical industry is a knowledge- and capital-intensive industry. With the development of science and technology, it has gradually developed from a small number of inorganic products such as soda ash and sulfuric acid, and organic products mainly made from husks to dyes, which have gradually developed into a multi-industry, multi-variety production department. A large number of chemical companies that have comprehensively utilized resources and scaled up.
Below we briefly analyze the two major industries in the chemical industry, the ethylene industry and the fertilizer industry using pressure detection instruments.
Vinyl
As of the end of 2009, the national ethylene production capacity reached 12.5 million tons/year. In 2010, with the successive completion and production of Tianjin Petrochemical and Zhenhai Refining & Chemical million-ton ethylene plants, the annual ethylene production capacity in China has reached 14.5 million tons. In spite of this, China's ethylene production capacity still cannot meet domestic demand, and improving domestic supply capacity is still an important task for China's ethylene industry in the future.
During the “Twelfth Five-Year Plan†period, there will be several sets of ethylene plants to be constructed in China. The downstream are all supported by polyolefins, styrene, ethylene glycol, styrene-butadiene rubber, butadiene rubber, neoprene rubber, and paraxylene (PX). And other production devices. It is expected that during the “12th Five-Year Plan†period, the production capacity and output of major synthetic materials will continue to grow rapidly. In 2011, China will add 1.18 million tons of ethylene per year. Fushun Petrochemical’s 800,000-ton/year cracker will be put into operation in the first half of 2011. Sichuan Petrochemical’s 800,000-ton/year cracker will be put into operation by the end of 2011. Lanzhou Petrochemical will expand its cracker capacity from 710,000 tons/year in 2011. 920,000 tons/year. In 2013, China will add 2.4 million tons/year of ethylene production capacity, including Wuhan Petrochemical's 800,000 tons/year new cracker. Daqing Petrochemical will increase its ethylene production capacity from 600,000 tons/year to 1,200,000 tons/year. Stimulated by the strong economic growth in China, China's ethylene production capacity will increase by 44% in the next three years to 19.08 million tons per year. By 2013, there will be 5 sets of new ethylene plants in operation in succession. The newly added ethylene capacity will be 5.85 million tons per year.
Fertilizer industry
The “Twelfth Five-Year Plan†of the chemical fertilizer industry issued by the China Petroleum and Chemical Industry Federation in 2011 pointed out that it is the top priority to control the total amount of fertilizer production. At the same time, it also proposed to promote industrial technological progress, increase the intensity of mergers and acquisitions of enterprises, extend the industrial chain of the industry, and lay out upstream industries to improve the economic efficiency of the industry.
At the end of the “Twelfth Five-year Plan†period, China needs 43.3 million tons of nitrogen fertilizer production, which requires a production capacity of 48 million tons; in 2015, the production capacity of phosphate fertilizer will exceed 21.5 million tons, and the output will reach 16 million tons. The industry plan mentioned that the contradiction between market supply and demand caused by overcapacity during the “12th Five-Year Plan†period and the cost-benefit contradictions caused by raw material prices were more prominent. In 2015, the proportion of urea production capacity was maintained at 64.5%, ammonium bicarbonate production capacity fell by half, and the proportion decreased to 6%; ammonium nitrate production increased significantly with the growth of nitro compound fertilizer, the proportion increased to 7.3%, and ammonium chloride continued to increase. With the development of Lianhua, the production capacity slightly increased, accounting for 7.7% of the total nitrogen fertilizer production capacity. The proportion of ammonium sulfate increased by 4.4% due to environmental protection and comprehensive utilization. The overcapacity of phosphate fertilizers has also been highlighted. In the past two years, the rapid development of the industry has caused the local supply of sulfur (pyrite), phosphate rock, synthetic ammonia, etc., and the excessive dependence on imports of sulfur and potassium resources has caused the industry to face severe challenges. Domestic consumption growth is slow, and export restrictions will persist for a long time. It is expected that by the end of the “Twelfth Five-Year Planâ€, China’s phosphate fertilizer production capacity will exceed 21.5 million tons, and its output will reach 16 million tons, which is fully able to meet domestic agricultural demand. By the end of 2015, the output of the top ten companies in the industry accounted for 60% of the total output, and the number of enterprises with phosphoric acid had been reduced from about 90 at present to about 50. The 12th Five-Year Plan for Phosphorus and Compound Fertilizer Industry proposes that no new construction and expansion projects will be completed within 3-5 years. Within three years, the existing pyrite-based sulphuric acid plant adopts a water-washing purification process, and 100,000 tons of pyrite-iron sulphuric acid plant and 200,000 tons of sulphur-based sulphuric acid plant are gradually withdrawn from the market; the utilization rate of phosphogypsum is less than 15%. Enterprises exit the market.
market capacity
Chemical companies usually have a measuring and testing center and several second-level testing centers. Each testing center is equipped with a set of pressure inspection tables, which are responsible for the verification of the on-site pressure gauges. The replacement period is five to eight years depending on the specific conditions. .
The pressure gauges used by chemical companies in the field mainly include general industrial tables and precision pressure gauges. The general industrial watch is mainly used for the measurement of the fluid pressure in the pipeline, and the precision pressure gauge is used for pressure monitoring with precise requirements. The replacement cycle is three to five years.
Ethylene and fertilizer industry are the two areas where the digital pressure testing instruments in the chemical industry are used in large quantities. The market capacity of digital pressure detection instrumentation in these two fields is about 265 million yuan in 2010, which is controlled by the state's total amount of chemical fertilizer industry. Affected, in the next few years, the demand for digital pressure detection instrumentation in China's chemical industry is mainly reflected in the replacement of inventory instruments. It is estimated that the market capacity of digital pressure detection instruments in China's chemical industry will be approximately 272 million yuan in 2011 and 294 million in 2015. Around Yuan, it maintained a slight increase, with a compound growth rate of approximately 2.1%.
Power generation and power supply
In the next five years, the development trend of coal-fired thermal power units in China will focus on the construction of power plant groups mainly around coal bases. According to national plans, during the “12th Five-Year Plan†period, China will focus on the development of Shanxi, North Shaanxi, Ningdong, Zhungeer, Ordos, Ximeng, Humeng, Huolinhe, Baoqing, Hami, Zhundong, Yili, Huainan. , Bin Chang, Jidong, Guizhou and other large coal power bases. During the 12th Five-Year Plan period, the planned size of coal-fired thermal power units across the country is estimated to be 300 million kilowatts, and thermal power installed capacity in 2015 will reach 933 million kilowatts.
After the separation of power generation and power supply companies, the state established two large power grid companies, namely State Grid Corporation of China and China Southern Power Grid Corporation. The power grid company has established power supply companies in various provinces, regions, and counties in China. Electric power scientific research institutes and multiple power construction companies have been established in each province. All thermal power installations are under construction by power construction companies. At present, China’s power construction companies have undertaken a large number of projects abroad. In 2010, the main business income of the State Grid Corporation of China was 1,542.7 billion yuan, and the company’s electricity sales amounted to 2,689,100 million kwh, with total assets of 2.1,192 billion yuan.
According to the standards for pressure test instrumentation in the thermal laboratory of a power plant, a rough estimate is made of the scale of digital pressure detection instrumentation required for power generation, and the demand of power supply system companies is estimated. Digital pressure detection instrumentation for power generation enterprises and power supply systems companies 2011 The market capacity for the year was 233 million yuan, a slight decrease in 2012 and a steady increase in the following years, reaching 349 million yuan in 2015. The market capacity of digital pressure detection instrumentation in China's power industry reached 448 million yuan in 2015, maintaining steady growth.
Metrology institutes and independent calibration agencies
According to the "Law of the People's Republic of China on Measurement", "the metrological administrative department of the local people's government at or above the county level shall, in accordance with the needs of the region, establish social public measurement standard instruments and be used after being qualified by the measurement administrative department of the higher people's government." The hospital plays a very important role in China's metrology system. Its legal liability research establishes measurement standards, conducts value transfer, enforces mandatory verification and other verification, inspection, and testing tasks stipulated by law, undertakes the drafting of metrological verification procedures, measurement technical specifications, and provides technical assurance for the implementation of measurement supervision.
According to different administrative levels, the accuracy level of digital pressure detection instruments and meters configured in China's metrology institutes also differs. The digital pressure detection instruments and meters of the National Institute of Metrology belong to the base, with an accuracy of more than 0.002%; the digital pressure detection instruments and meters of provincial and municipal level metrology institutes belong to the standard level, with an accuracy of 0.05%-0.4%. The accuracy of digital pressure detection instrumentation in provincial and municipal measurement institutes is 0.05%-0.01%, and the commonly used accuracy levels include 0.01%, 0.02%, and 0.05%; the accuracy of digital pressure detection instrumentation in county-level metrology institutes Degrees range from 0.1% to 0.4%. Commonly used accuracy levels include 0.1%, 0.2%, and 0.4%.
The accuracy of the digital pressure detection instruments and meters that this report focuses on is in the range of 0.1%-0.05%, including the pressure gauges of the provincial-level metrology institutes, the pressure gauges of some metrology institutes in the county-level cities, and the pressure of some metrology institutes at the county level. meter. In addition, with the opening of China's calibration market, a large number of independent calibration agencies exist. Based on a rough estimate, the market capacity of digital pressure detection instruments and meters for measurement institutes and independent calibration agencies in China in 2011 was approximately 180 million yuan.
mechanical
Digital pressure detection instruments are mainly used in the production workshops and laboratories of machinery manufacturers. The parts of the production site where the pressure gauges need to be configured are mainly pipes and equipment, and 1-2 sets of pressure gauges need to be configured at each pressure measuring point. With the increasing precision of the process parameters of the mechanical industry, more and more manufacturers are required. The use of high-precision pressure gauges has made this trend particularly evident in the past five years; currently, the accuracy of pressure gauges used in production sites is mostly below 1%. In the future, replacement of pressure gauges will gradually replace pressure gauges with an accuracy of 0.1% or more. Currently using the table, the market price of each table is about 1000-2000 yuan.
In addition, in order to cooperate with the inspection of production pressure gauges, general machinery manufacturers are equipped with laboratories of different sizes. The main function of laboratory pressure gauges is inspection. Each laboratory is equipped with at least 1-2 sets of pressure gauges. Each set of pressure gauges includes 30-40 gauges with different ranges and different accuracies. The accuracy is tens of thousands. It is roughly estimated that the market capacity of digital pressure testing instruments and meters for mechanical production units in 2011 will be approximately 170 million yuan, which will continue to grow steadily in the next few years due to the downstream oil and electric power industries. The market capacity in 2015 is expected to be around 210 million yuan.
