Weld Neck Flange

Weld Neck Flange
Weld Neck Flange

A weld-neck flange has a neck and a round tube transition. It is attached to a pipe, so it is also called high neck flange or long neck flange.

Long neck form gives it extra strength and stability, and it can be used in many industrial settings.

It is a type of flange that is made to work in places with high temperatures and pressure. It can be used for oil transportation pipelines, ship pipeline systems, and the transport of raw materials in chemical plants, among other things.

Because it has a high structural strength, good sealing performance, resistance to corrosion, and the ability to withstand high temperature and pressure.

Usually weld neck flange can be divided into neck butt welding flange and neck flat welding flange according to the welding process. You can view various weld neck flanges we have produced through the gallery below.
