Stainless Steel Socket Weld Fittings are a type of forged fittings designed for use in piping systems where high-pressure and corrosive conditions are present. These fittings are specifically crafted from the stainless steel grades 304, 304L, or 304H, each serving a particular purpose.
Stainless Steel Threaded Fittings are a type of forged fittings designed for use in piping systems where threaded connections are preferred. These fittings are crafted from the stainless steel grades 304, 304L, or 304H, each offering specific properties for different applications.
Strength, leak resistance, and durability are key advantages. They are suitable for high-pressure systems.
Threaded fittings can be assembled without welding, making installation quicker and easier. They are suitable for low-pressure applications.
Choose 304 for general corrosion resistance, 304L for welding without post-weld annealing, and 304H for high-temperature applications.
Socket weld fittings require welding during installation. Threaded fittings, on the other hand, do not require welding.
