Long Neck Weld Flange ASME B16.5

Long Neck Weld Flange is an indispensable part in pipeline construction. It is formed by high-temperature and high-pressure forging of raw material metal round bar or plate. Through heat treatment and tempering, it has higher performance of corrosion resistance, high-pressure resistance, high-temperature resistance and low-temperature impact resistance.

Carbon steel, low temperature pipeline steel, stainless steel, dual phase steel, nickel base alloy – Long Neck Weld Flange

Cangzhou Enfei Pipe Equipment Co., Ltd. is an excellent Long Neck Weld Flange manufacturer in China,The Long Neck Weld Flange is a product formed by high-temperature and high-pressure forging of the raw material metal round bar or steel plate. Therefore, the Long Neck Weld Flanges has high requirements for raw materials.
