A weld neck flange, one of the most common types of flanges, features a long inching hub that can be welded with a pipe. This flange type is used, typically, in high-pressure and high/ low temperatures applications that want an unrestricted inflow of the fluid conveyed by the pipeline. The absence of pressure drops prevents negative things like turbulence and corrosion/ erosion of the raw material in the proximity of the flange joints. The tapered base allows a smooth distribution of the mechanical stress between the pipe and the weld neck flange and facilitates the prosecution of radiographic examinations to detect possible leakages and welding scars.

Weld Neck Flange Catalogue

The dimension of the Industrial Flange (schedule & NPS) shall match the dimensions of the connecting pipes. Thus, when ordering Steel welding neck flanges, the Customers shall inform the suppliers about the nominal sizes and wall density of the connecting pipes. A Industrial welding neck flanges are connected to a pipe by a single full penetration V-shaped butt weld.
