Steel Weld Neck Flange - China

A weld neck flange is a type of industrial 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 known 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.
