Forged Weld Neck Fittings And Flanges Carbon Steel / Stainless Steel / Cu Ni Flange
Forged Weld Neck Flange fittings and flanges Carbon Steel / Stainless Steel / Cu Ni flange
Pipe flanges are protruding rims, edges, ribs, or collars used to make a connection between two pipes or between apipeand any type of fitting or equipment component. Pipe flanges are used for dismantling piping systems, temporary or mobile installations, transitions between dissimilar materials, and connections in environments not conducive to solvent cementingA.
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 piping system, high or low temperature conditions.
