ANSI 304 304L 316 316L Stainless Steel Forged BS4504 RF Carbon Steel Threaded Pipe Flange
There are two types of threaded flanges. One is to seal the two pipe ends with a certain sealing surface and a lens pad. This type of flange is mostly used for ammonia production. But it has been used less recently, and the lens pad has been replaced by a metal ring.
The other type is the same as a normal flange, sealed with two flange sealing faces.
There are two facing types for threaded flange, raised face flange and ring joint flange.
