Are distinguished from other types by their long tapered hub and gentle transition of thickness in the region of the butt weld joining them to the pipe. The long tapered hub provides an important reinforcement of the flange proper form the standpoint of strength and resistance to dishing. The smooth transition from flange thickness to pipe wall thickness effected by the taper is extremely beneficial under conditions of repeated bending, caused by line expansion or other variable forces, and produces an endurance strength of welding neck flanged assemblies equivalent to that of a butt welded pipe. Thus this type of flange is preferred for every severe service condition, resulting from high pressure or sub-zero/elevated temperatures, and whether loading conditions are substantially constant or fluctuates between wide limits:welding neck flanges are particularly recommended for handling high explosive, flammable or costly liquids, where loss of tightness or local failure may be accompanied by disastrous consequences.
