Socket Weld Flanges are manufactured, exported, and supplied by Katariya Steel Distributors, a prominent and leading manufacturer, exporter, and supplier. We use the highest-quality raw materials available on the market to create our products. We sell Socket Weld Flanges at a competitive price range as one of India's most reputable suppliers.

Socket Weld Flange is also known as SW Flanges. They have a recessed area in the flange bore, this shoulder serves as a guide to set the depth of the pipe that is inserted into the flange. These Socket weld flanges are suitable for high-pressure small diameters piping systems. Socket weld flange has RF type and RTJ type.

RF socket weld flange has a small portion surrounding the flange bore that protrudes from the face. Gasket seats will be placed in this raised area. RTJ socket weld flange has raised face surface that has a groove RTJ type, which you can place a gasket ring to get better sealing performances. Socket weld flanges can minimize the risk of leakage.

These socket weld flanges don’t need to be bevelled before welding. Another advantage of having these socket weld flanges is that welding work outside of the pipe will not penetrate the pipe bore. Socket weld flange static strength is equal to slip-on flange but its fatigue strength is 50% higher than the double welded slip-on flange. These socket weld flanges are suitable for applications where internal welding operations are particularly difficult.

We make sure that all our products are tested several times to ensure the product quality, safety and durability. We verify our products before supplying them to our esteemed customers. These socket weld flanges are widely used in steel plants, sugar mills and distilleries, pumps and petrochemicals, the cement industry and many other popular industries due to their amazing properties.
