Alloy Steel Flange

Alloy steel flange is different from the common 20#, Q235 carbon steel flange, mainly used for special characteristics of pipelines and pipelines, more used for high temperature and high pressure position.Its common materials are 12Cr1MoV, 15CrMo, P91, P22, 10CrMo910 and so on.Alloy steel flanges can be divided into national standards (ministry of chemical industry standards, petroleum standards, power standards), American standards, German standards, Japanese standards, Russian standards and so on.Alloy steel flange of main resources and main application parameters are as follows: alloy steel flange of the reference standard, alloy welding neck flange manufacturing method choice, chemical composition analysis, mechanical performance, corrosion performance of detection, the main method of heat treatment, the tensile and hardness tests, alloy for the welding process in the process of installation. Alloy steel flange is one of the most widely used parts in petrochemical industry and is an important pipeline equipment in petrochemical industry.Butt welded flanges are used in pressure vessels and cryogenic vessels because of their excellent compressive stress and low temperature resistance.Alloy flanges have been used in chemical pipelines because of their corrosion resistance and oxidation resistance.In addition, by changing the content of chromium in alloy steel flanges and adding other alloying elements, it can also be used in ships, offshore oil exploration, aviation lights.
