Weld neck flange is a type of steel flange designed to transfer stresses to the pipe to reduce high stress concentrations at the base of the flange.
A weld neck flange (WN flange) means a flange has a neck for weld with the pipe, it is easily to recognized by their long tapered neck on the flange (The neck is also called hub in the weld neck flange). The tapered neck can supply a high strength reinforcement to support flange and pipe. It means the weld neck flange is suitable to used in high pressure and extremely temperature situation.
Our weld neck flanges feature high strength,good toughness,and high reistance to corrosion,high pressure and temperature.The raw materials of them come into carbon steel,stainless steel,alloy steel,low temperature steel and high performance steel.Also,we can provide customized flanges according to customers'requirements.
