Socket Weld Flanges / SWRF Flanges, ASTM A182 Socket Weld Pipe Flanges, Carbon Steel A105 Socket Weld Flanges,  Manufacturers in India

Unifit Metalloys Inc. is a prominent producer, supplier, distributor, and exporter of various sizes, materials, and grades of Socket Weld Flanges. Welding Sockets Flanges were mass-produced for use on small-diameter high-pressure pipework. Our supplied range is known for its dimensional correctness and durable construction, and it is available in a variety of specifications. It has a longer fatigue life due to the constant internal pressure as opposed to sliding on the flange.

Socket Weld Flanges are made from high-quality materials. It’s recommended for industries where interior welding is very challenging. This sock welded structure avoids internal pockets while avoiding welding heat surface roughness and weld spatter damage to the flange face.

Socket Weld Flanges are stronger and have superior fatigue resistance than slip-on flanges because they have an inside weld. Also, the corrosive or radioactive environment will not be compatible with the socket weld flange, as the solid buildup at the joint can cause operational and maintenance issues.
