Carbon Steel/CS WNRF/Weld Neck Flange

WNRF OR Weld Neck Flanges are easy to recognize at the long tapered hub, a transition from Integral flange thickness to pipe or fitting thickness effected by the taper is beneficial, The Weld Neck Flange caused by line expansion or other variable forces. These flanges are bored to match the inside diameter of the mating pipe or fitting end so there will be no restriction of product flow. This prevents turbulence at the joint and reduces erosion from the transition. They also provide excellent stress distribution through the Long hub and are easily radiographed for flaw detection. The Long Weld Neck flange type will be welded to a pipe or fitting with a single full penetration, V weld (Buttweld).
