ASTM A182 F5 Flanges chemical composition and mechanical properties. The ASTM A182 F5 Flange is constructed of chromium molybdenum steel. It is lightweight and has a high rupture resistance. It is also resistant to hydrogen attack and cracking caused by sulfide corrosion. The material Alloy Steel ASTM A182 F5 Flanges is widely used in the petrochemical and power generation industries. These flanges are widely used in a variety of industries such as power generation, gas processing, oil drilling, pharmaceuticals, and seawater equipment.
Blind flange is mainly used to seal the end of pipelines, to isolate, seal or temporarily seal pipeline systems. During maintenance or repair, it can also conveniently remove debris from pipelines. It has a similar sealing effect as the head and pipe cap, but the blind flange can be disassembled for further modification or assembly of the pipeline.
Wuxi Changrun manufactures forged flanges and various forgings for various boilers and pressure vessels according to international and national standards (ASME, ASNI, DIN, GB, JB/T, SH, HG, DG, etc.) with various materials (carbon steel, alloy steel including steel used for high-temperature and low-temperature, stainless steel including duplex steel and etc.). The products are widely used in petroleum & chemical industry, electric industry (nuclear power, wind electricity, thermal power), light manufacturing, machinery, metallurgy, ship craft and etc.
