Long Weld Neck Flange Suppliers

We as Metalfed Engineering are a prominent exporter and supplier of Long Weld Neck Flanges, which offers easy cleaning and high strength with low weight. Rasied Face Long Weld Neck Flange is used for forgings where its strength, toughness, and corrosion resistance make its use appropriate. Long Weld Neck RTJ Flanges is a slightly higher carbon version and is more resistant to corrosion due to the higher nickel content. ASME B16.5 Long Weld Neck Flange resists corrosion and maintains its strength at high temperatures and is easy to care for. Stainless Steel Long Weld Neck Flanges become increasingly magnetic when cold worked. With slightly lower chromium content than its counterpart, it is composed of carbon, chromium, nickel, manganese, silicon, sulfur, and phosphorus.
Susceptibility to carbide precipitation during welding limits the use of these 300# Long Weld Neck Flanges in some applications. It also offers good weldability and better wear resistance and fatigue resistance. They are formed by rolling the plate and welding the seam. Again and again, Carbon Steel Long Weld Neck Flanges have tighter dimensional tolerances than seamless and can be cheaper when made in the same quantities.
