Forged fittings are manufactured by forging steel, which increases strength and reliability. They are available in:
Threaded (Screwed) Ends
Threads conform to NPT (National Pipe Thread) standards. No welding is required—simply screwed into place.
Socket Weld Ends
Pipes are inserted into a recessed area and welded around the joint—ideal for high-leakage integrity.
Alloy Steel
ASTM A182 F1/F5/F9/F11/F22/F91 etc.
