Product Summary

Welded neck flange has high hub,which is designed to relieve the high pressure at base of flange, and is butt-welding flange which is best designed.WELDING NECK FLANGES 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 from 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 joint between pipes, which, in practice, is the same as that of unwelded pipe. Thus this type of flange is preferred for every severe service condition, whether this results from high pressure or from sub-zero or elevated temperature, and whether loading conditions are substantially constant or fluctuate between wide limits. Besides,the main materials of it are carbon steel,stainless steel,alloy steel,nickel alloys and duplex stainless steel etc.Weld Neck Flanges are drilled(machined) with the wall thickness of the flange having the same dimensions of the matching pipe, the lighter the pipe is, the larger the bore, conversely, the heavier the pipe, the small the bore, they are normally used for highpressure, cold or hot temperature.This flange is circumferentially welded into the system at its neck which means that the integrity of the butt welded area can be easily examined by radiography. The bores of both pipe and flange match, which reduces turbulence and erosion inside the pipeline. The weld neck is therefore favoured in critical applications. In addition,the Weld Neck Flanges are widely applied to many lines such as oil and gas industry, chemical plant, electric power, smelting, water c
