Kisaan Steels Threaded Flanges

Threaded (Screw) Flanges

The Threaded Flange is similar to the slip-on flange, but the bore is threaded. Its chief merit is that it can be assembled without welding, explaining its use in low pressure services at ordinary atmospheric temperatures and in highly explosive areas where welding create a hazard.

These flanges are used in special requirements to work under high temperature and pressure, making sure no welding joint is made at the assembly.
