Duplex steel flanges have excellent resistance to stress corrosion cracking

Duplex steel flange with dual-phase steel, ingot or sheet for the production of raw materials such as the flange is called dual-phase steel flange, flange, also known as the flange or flange. Is the pipe and pipe interconnecting parts. Connect to tube end. There are holes in the flange, you can wear bolts, so that the two flanges closely linked. Flange sealed with gasket.(welding overlay,flange,pipe spooling)


Flange connection by a pair of flanges, a gasket and a number of bolt nut composition. Gasket on the flange between the two flanges, tighten the nut, the gasket surface than the pressure reaches a certain value after deformation, and fill the sealing surface uneven, so that the connection tight leakage. Some fittings and equipment have their own flange, also belong to the flange connection. Flange connection is an important connection for pipeline construction.(welding overlay,flange,pipe spooling)


Duplex steel flanges have a yield strength that is more than double that of stainless steel flanges compared to stainless steel flanges Duplex steel flanges have excellent resistance to stress corrosion cracking, especially in chloride environments Super Duplex Very good acid resistance of steel. Anti-wear capacity is much higher than the stainless steel flange. If conventional stainless steel flange can be used for one year, then the dual-phase steel flange can be used for at least six years.(welding overlay,flange,pipe spooling)
