What is the difference between flat welded flange and welding socket flange?

　　In HG, the standard of flat welding flange and welding socket flange is different. In addition, the flat flange is a concave with a slightly larger diameter than the outer diameter of the pipe, and the pipe is welded in it.

　　Features of various flanges:

　　Socket flange suitable for small diameter, high pressure, high temperature pipe connection,especially ASME B16.5 Carbon Steel Welding Socket Flange.

　　Flat welding is like butt welding with a convex platform with a groove on it, and then the pipe is stuck in it.

　　The socket flange is without a convex platform, and a groove is opened directly on the flange body, like a hole in the blind flange, and then a groove is opened.

　　The welding performance of flat flange is better than that of socket flange.
