Welded flange

　　Also known as high-neck flange welded flanges, welded flange it different is that from the flange and pipe flange welds to have a long and lean high neck, high neck wall thickness of this paragraph gradual transition to the height direction of wall thickness, improved stress discontinuity, thereby increasing the strength of the flange.

　　Welded flange relatively harsh conditions mainly for the occasion, such as a pipe thermal expansion or other load leaving the flange repeated occasions by stress or stress larger, pressure, temperature fluctuations pipe or high temperature, pressure and Freezing pipes.

　　We have adopted advanced production equipment and technologies to manufacture our socket flanges and threaded flanges,which can not only improve product quality, but also save raw materials. Our products have high strength, good toughness and resistance to corrosion

　　According to the type of welded flange sealing surface can be divided into: flat welded flange, welding flange raised face, convex face welding flange, tongue and groove face welding flange, welding flange ring joint face.
