Overview
The ASTM B564 UNS N06600 alloy is used in a variety of corrosion resisting applications. The high nickel content of Alloy 600 provides a level of resistance to reducing environments, while the chromium content of the material provides resistance to weaker oxidizing environments, the material provides exceptional resistance to chloride-ion stress-corrosion cracking.
Welding 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 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.
These 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.
