ANSI B16.5 WELD NECK FLANGE

A weld neck flange is a type of steel flange designed to transfer stresses to the pipe to reduce high stress concentrations at the base of the flange.Compared with other types,weld neck flanges are know for their tapered hub and gentle transition from flange thickness to pipe wall thickness.They are deformation-resistant,and are normally used for high pressure,high or low temperature conditions.
