Socket Weld Flanges

ASME/ANSI B16.5 SOCKET WELDING FLANGES MANUFACTURER IN INDIA MANUFACTURER/EXPORTER OF HIGH QUALITY SOCKET WELDING FLANGES CARBON, ALLOY, STAINLESS STEEL SOCKET WELD FLANGES

Socket weld flange is similar to the slip-on flange in outline, but the bore is counter-bored to accept pipe. Socket welding pipe flanges are typically used on smaller sizes of high pressure pipes. Socket weld flanges are widely used in high pressure systems such as hydraulic equipment and steam lines. Socket weld pipe flanges are attached by inserting the pipe into the socket end and then applying fillet weld around the hub of the flange. This allows for a smooth bore and better flow of the fluid or gas inside of the pipe. An optional internal weld may be applied in high stress applications.

We offer socket welding flanges manufactured at our facility to companies in various industries including shipbuilding, power generation, petrochemical plants, oil refineries, waste water treatment plants, paper mills, pharmaceutical plants and turnkey projects among others.

Marking & Packing

Products are packaged to ensure that there is no damage during transit. In case of exports, standard export packaging is done in wooden cases. All flanges are marked with Grade, Lot No, Size, Degree and our trade mark. On special requests we can also, make custom marking on our products.

Quality Assurance

At Vandan Alloys, all fittings and flanges are subject to strict inspection at each stage of the production process, from starting material purchasing to product dispatch. They are visually examined for conformity to ASTM, ASME, MSS, DIN, EN, and JIS codes and standards. Upon request, official certified Inspection Agencies can be called in to witness the material reports, dimensions and quality conformity of products.
