Stainless steel threaded flange will be developed rapidly

　　The overall level of the Chinese flange industry has been greatly improved, but the quality is still not stable, such as running, running, dropping, leakage phenomenon in the domestic 150lb ASME B16.5 A182 F321 Threaded Flange often appear. In addition, there is still a certain gap between China's flange matching capacity and developed countries. With the fierce competition in the flanges market, the market of some low-end threaded flange products has become saturated and the supply of supply exceeds demand, which makes the development of small and medium-sized enterprises more and more difficult.

　　Even those with relatively high technology content compete fiercely in the international market. At present, China is in the flange market, but still depends on the import in the field of high end valves, which is also the field in which China's valves need to make a breakthrough in the future in order to truly promote the development of China's valve industry.

　　But since last year, the localization of high-end valves has become a difficult road. At present, the basic parts have become a short board to restrict the development of domestic manufacturing industry to high-end. In 12th Five-Year, China's efforts on the localization of high-end equipment components will be further strengthened. The feasibility of valve import substitution in China's sub sectors is quite different, and high-end valves need more policy guidance and scientific research support.

　　Stainless steel threaded flange have excellent properties for many kinds of other metals. It is a kind of material with excellent durability and recycling. In the future, the stainless steel flat welding flanges will be widely used in various fields for the change of the times.
