What is a Threaded Screw Flange?

A threaded screw flange is a type of flange that connects to pipes via internal threads, eliminating the need for welding. This makes it ideal for:

Corrosive environments where welding could cause damage

Temporary or adjustable piping systems

Low to medium-pressure applications

RF (Raised Face) or FM (Flat Face) designs ensure proper gasket sealing and leak-free connections.
