Process Standard and Quality Control of Socket Flange

　　Socket flanges is mainly used for butt welding of flange and pipe.Socket flanges are structure is reasonable, strength and stiffness are large, and  Socket flanges can withstand high temperature, high pressure, repeated bending and temperature fluctuation.

　　Knowledge of Galvanized Weld Screwed Stainless Steel Socket Flanges.Socket flanges is a kind of flange with neck and pipe transition and  Socket flanges with pipe, which is a kind of pipe fittings. The advantages of  socket flanges are anti-corrosion, acid and alkali resistance, long service life, and reasonable price calculation, smooth surface, acid and alkali resistance and high temperature resistance. Socket flanges has the characteristics of not easy deformation and good sealing.Socket flanges  can be used on pipelines with large fluctuation of pressure or temperature, or on pipelines with high temperature, high pressure and low temperature, or on pipelines with expensive, flammable and explosive media.

　　Process standard and quality control of socket flanges : feeding - physicochemical - cutting - hot forging - heat treatment - Inspection - gold processing - finished product inspection - marking - finished product inspection - marking - packaging typing - shipment. Welding installation of socket flanges  requires double-sided welding of flange. The socket flanges  are not all need internal and external double-sided welding, there is no special requirement is generally only external welding, did not see 1/2 "of the flat welding is better welding, because the pipe and flange are good for vertical, the pipe will not oblique.
