Stainless Steel Welding Neck Pipe Flanges
As a professional Carbon steel and Stainless Steel Welding Neck Pipe Flanges manufacturer and supplier, Metleader' R&D dept. are concentrating on upgrading process level continuously. Stainless Steel Weld Neck Pipe Flanges do not produce corrosion, pitting, rust or wear, because stainless steel is one of the highest strength materials in building materials, and welding neck flange are commonly referred to as "high hubs", whose purpose is to transfer pressure to the pipe, thereby reducing the high stress concentration in the flange.
The Welding Neck flange has a the complex neck looks like a mouthwash, which suitable for the pipelines that undergo large range of fluctuations in pressure or temperature, or high temperature, high pressure and low temperature. Generally used for PN greater than 2.5MPa piping and valves are also used for transporting expensive, flammable and explosive media.
