Stainless steel flange manufacturers Analysis: Regional will become the biggest obstacle to the development of the flange
China is a world power with the third largest land area in the world. Different regions have different cultural differences. Because of this, there are also great differences in the use of flanges, especially in Northeast China, North China, Northwest China, and South China. This forces flange manufacturers to produce different flanges according to different regions when producing valves, which undoubtedly increases the burden on enterprises.
However, from the market survey in our country, the general-purpose flanges in our country are generally unqualified, which greatly restricts the development of general-purpose flanges, and also magnifies the restriction of regionality in the development of flanges. Industry insiders believe that the reasons for the high failure rate of general-purpose flanges in my country are mainly due to the backward technology of production enterprises, lagging implementation of technical standards, incomplete evaluation rules, and deteriorating market environment.
From the perspective of foreign markets, at present, the products of some world-famous flange brands have developed into general-purpose flanges, such as Fisher, Masoneilan, etc. This has also prompted the rise of some professional flange companies, and at the same time, some large companies will develop general-purpose flanges by setting up subsidiaries. In the production line of enterprises, in view of the differences in the flange market, many enterprises have been continuously integrating product lines, developing marketable products, and making the product series as versatile and diversified as possible.
The flange industry should accelerate the establishment of a new technology development system with independent development and innovation capabilities based on aspects such as optimizing industrial structure, energy conservation and environmental protection, independent innovation, reform and opening up, and people-oriented. In terms of localization of products in the flange industry, 95-100% of large-scale ethylene special flanges should be covered. Coal chemical special flanges are mainly the key to high-temperature hydrogenation. The material sealing pair should be solved, and some control and driving devices should also be achieved. More than 90%; in terms of ultra-supercritical thermal power station technology, etc., the localization ratio of flanges should reach 85%-100%.
By digesting and absorbing imported technology and conducting independent research and development, especially after the domestication of ultra-supercritical thermal power flanges during the "Twelfth Five-Year Plan" period, the manufacturing level and product quality of thermal power flanges in my country have been greatly improved. Supercritical and ultra-supercritical thermal power plants provide a large number of critical flanges.
All in all, as an important factor restricting the development of flanges in our country, if we do not make breakthroughs, the regionality will cause huge losses to the flange industry in our country.
