Table Of Content


A weld neck flange (also known as a high-hub flange and tapered hub flange) is a type of flange. There are two designs. The regular type is used with pipes.

These pipe flanges attach by welding the pipe to the neck of the flange. This transfers stress from the flange to the pipe instead. It also reduces the stress concentration from the base of the hub. Weld neck flanges are often used for applications where high pressure is a factor. The inside diameter of the flange is designed to match the pipe's inside diameter. Weld Neck Pipe flanges with a hub have published specifications that range from 1/2" thru 96". Our company provides these in all material grades, specifications and sizes. Weld neck pipe flanges are typically provided with a raised face, flat face, or RTJ facing. When a raised face is necessary for weld neck pipe flanges, the standard height is 1/16" for weld neck pipe flanges under 400#. For weld neck pipe flanges of 400# and up, the standard weld neck pipe flange raised face height is 1/4".

DM Special Steel Ltd manufactures weld neck pipe flanges in all steel material grades, including carbon weld neck pipe flanges, stainless steel weld neck pipe flanges and alloy weld neck pipe flanges. DM Special Steel Ltd also has many different weld neck pipe flanges in stock and ready to ship. Weld neck pipe flanges in stock include ANSI B16.5 weld neck pipe flanges, ASME B16.47 Series "A" weld neck pipe flanges, ASME B16.47 Series "B" weld neck pipe flanges, Pressure Vessel weld neck pipe flanges. DM Special Steel Ltd also manufactures custom weld neck pipe flanges per customer requirements.

Weld neck pipe flanges are connected to the pipe by welding the pipe to the neck of the pipe flange, which helps to pass on the stress from the weld neck to the pipe itself. This also reduces high stress concentration at the base of the hub of the weld neck pipe flanges. Weld neck pipe flanges are generally used in high pressure applications, where hot or cold temperatures exist. The inside diameter of a weld neck pipe flange is machined to match the inside diameter of the pipe.
