F304 F304L F316 F316L 31803 32750 Stainless Flange

F304 F304L F316 F316L 31803 32750 Stainless Steel Weld Neck Flange

　　Weld Neck Flanges are easy to recognize at the long tapered hub, that goes gradually over to the wall thickness from a pipe or fitting.

　　The long tapered hub provides an important reinforcement for use in several applications involving high pressure, sub-zero and / or elevated temperatures. The smooth transition from weld neck flange thickness to pipe or fitting wall thickness effected by the taper is extremely beneficial, under conditions of repeated bending, caused by line expansion or other variable forces.

　　Weld Neck Flanges are bored to match the inside diameter of the mating pipe or fitting so there will be no restriction of product flow. This prevents turbulence at the joint and reduces erosion. They also provide excellent stress distribution through the tapered hub and are easily radiographed for flaw detection.

　　The flange type will be welded to a pipe or fitting with a single full penetration, V weld (Buttweld).
