Steel Pipe Welding Neck Flange
The neck butt welding flange refers to a flange with a tapered neck and butt welding with the cylinder or pipe. It is an integral flange. Due to the excessive structure of the taper neck and the butt welding connection, the strength and rigidity of the flange are enhanced, the butt welding flange is not easy to deform, has good sealing, and is widely used. The sealing surface forms are: raised surface (RF), concave surface (FM), convex surface (M), tenon surface (T), groove surface (G), full flat surface (FF), ring joint surface (RJ).
