Forged Steel Pipe Fittings

Forged steel pipe fittings are made of A105 (carbon steel), stainless steel or nickel alloy. Forging steel is a process that creates very durable fittings. These fittings are used for connecting pipes, pumps, valves & other equipments in the pipeline system. They are thicker, heavier and are intended for heavy industrial use. Forged Fittings are available in 2000#, 3000#, and 6000# pressure class. These fittings are more common in 3000# and 6000# (90% of the time).
