Welding neck flange have two forms (shapes), one with reducing neck as we called reducing weld neck flange; One with a even diameter of typical long neck named as long neck weld flange.
Weld neck flange (WN flange) has a neck that can relocated stress of the pipe, so to reduce the pressure that gathered in the flange bottom. It is compatible to the pipelines that works in high or low temperature and bear high pressure. Specially for the pipe or the valves when PN is larger than 2.5 Mpa.
Applications and Features
Weld neck flange mainly used in medium, high pressure pipes connecting, most butt weld flange with neck also called nipple flange.
Therefore, the installation cost of the welding flange, labor costs and auxiliary materials costs are higher, because there is more than one process.
