Stainless steel integral flange belongs to a kind of butt welded steel pipe flange with neck. In various domestic standards, if is used to represent the integral flange. It is mostly used in pipelines with high pressure. The production process is generally casting. The pipe end of integral flange is thicker than that of butt welding flange, and the internal diameter of integral flange is the same as the nominal diameter except for PN1.6MPa and dn450.

Stainless steel integral flange is generally raised surface (RF). If it is used under flammable, explosive, high and extremely hazardous conditions, the sealing surface of convex concave surface (MFM) and tenon groove surface (TG) other than RF surface can be selected.
