1. Socket weld flanges. JIS B2220 SOH FLANGE manufacturers tell you that a socket welding flange is a flange that is welded to a steel pipe at one end and bolted at the other end. JIS B2220 SOH FLANGE manufacturers tell you that its sealing surface forms are raised surface (RF), concave-convex surface (MFM), tongue and groove surface (TG), and ring joint surface (RJ).

JIS B2220 SOH FLANGE manufacturers tell you that its application range is boiler pressure vessel, petroleum, chemical industry, shipbuilding, pharmaceutical, metallurgy, machinery, stamping elbow food, and other industries. It is often used in pipelines with PN≤10.0MPa and DN≤40.
2. Threaded flange. JIS B2220 SOH FLANGE manufacturers tell you that the threaded flange is a non-welding flange that processes the inner hole of the flange into pipe threads and matches with the threaded pipe to realize the connection.
The above information is the JIS B2220 SOH FLANGE manufacturer's introduction and analysis of the integral flange, hope it helps you.
