Analysis of LED product prices is expected to drop by 20% this year

LED products will be cut by 20 this year. The whole industry is optimistic about production and sales in the context of weak macroeconomic growth. Manufacturers are still competing to expand, and the relevant standards are also highly competitive. Dai Xin, vice president of Maoshuo Power, said: This year is generally considered to be a turning point in the development of the semiconductor lighting industry. The LED industry has recovered, and many companies have reported a significant increase in performance at the beginning of the year. In the past two or three years, it will be a period of rapid development of the industry. The market that will be launched in September of the previous year has been launched in May and June. At present, the company's sales have doubled compared with the same period. Osram Zhang said: The price of LEDs will drop by 20. The most profitable part of the lighting industry is semiconductor lighting and automotive lighting. Tang Guoqing, general manager of Samsung LED China, believes that the current price of LED lamps has dropped to the level equivalent to traditional lighting, LED will be the protagonist of lighting in the next decade. However, there are standards missing in its industry. The marketization of LED lighting components has also begun, and the lighting components are moving toward national standards. At the LED Standard Testing Forum held yesterday, the standard optical components competed with the international standard ZHAGA. Different standards of the camp are vying for members to join.

DIN 2631 Welding Neck flange

Welding neck flange are distinguished from other types by their long tapered hub and gentle transition of thickness in the region of the butt weld joining them to the pipe. The long tapered hub provides an important reinforcement of the flange proper from the standpoint of strength and resistance to dishing.
The welding neck flanges are normally referred to as the high hub flange. It is designed to transfer stresses to the pipe, thereby reducing high stress concentrations at the base of the flange. The welding neck flange is the best designed butt-welded flange of those currently avaliable because of its inherent structural value. It is expensive because of the design.
