Threaded Flanges

Threaded flanges connect to pipes via NPT or BSP threads, eliminating the need for welding. They are used in small-bore, low-to-moderate pressure applications and in situations where welding is not feasible (e.g., explosive atmospheres or existing lines). Shree Raj Steels supplies threaded flanges from 1/2" to 4" in Class 150 through 2500.
