We offers a range of Weld Neck Flanges, to which as the name suggest it’s a neck part of the flange that is being welded to the closing stages of the pipe system. Weld Neck Flanges are having an extensive tapered focal point and are frequently used for soaring pressure applications. It is in fact designed to move pressure to the pipe, in that way dipping high pressure concentration at the bottom of the flange.

Weld Neck Flanges are well-known from other kinds by their extensive pointed centre and moderate evolution of width in the butt weld area, by connecting them with the pipe. Meanwhile the extensive pointed centre offers a significant support of the proper flange, from the position of resistance and strength to dishing.

As a result, these types of flanges is picked for every service condition that is severe, whether this outcomes from elevated or sub-zero temperatures, or from high pressures, and whether loading circumstances are considerably fluctuate or constant between the wide limits.
