Long Neck Weld Flange

Weld neck flange (WN flange) has a neck and it is designed to transfer stresses to the pipe, thereby reducing high stress concentrations at the base of the flange. 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.
