Weld neck flange
A weld neck flange (also known as a high-hub flange[1] and tapered hub flange[2]) is a type of flange. There are two designs. The regular type is used with pipes. The long type is unsuitable for pipes and is used in process plant.[3] A weld neck flange consists of a circular fitting with a protruding rim around the circumference. Generally machined from a forging, these flanges are typically butt welded to a pipe. The rim has a series of drilled holes that permit the flange to be affixed to another flange with bolts.[4]
Such flanges are suitable for use in hostile environments that have extremes of temperature, pressure or other sources of stress.psi.[2]
