Socket Weld Flange

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

India's SK Tube Corporation is a specialized producer of industrial socket welding flanges that meet ASME, ANSI, and DIN standards for quality. For common size carbon steel and stainless steel socket weld flanges, we provide fast delivery options. Just-in-time procedures can be used to supply socket welding flanges made in certain stainless steel grades, nickel alloy, and alloy steel that are kept in stock.

The form of a socket weld flange is similar to that of a slip-on flange, but it has a counter-bored opening to accommodate pipe. Smaller high pressure pipe diameters are usually fitted with socket welding pipe flanges. A lot of high pressure systems, such steam lines and hydraulic machinery, use socket weld flanges. Fillet weld is applied around the flange hub after the pipe is inserted into the socket end to attach socket weld pipe flanges. This makes it possible for the fluid or gas inside the pipe to flow more smoothly and efficiently. Application of an optional internal weld is possible in high stress scenarios.

We provide organizations in a variety of industries, such as shipbuilding, power generation, petrochemical plants, oil refineries, waste water treatment plants, paper mills, pharmaceutical facilities, and turnkey projects, with socket welding flanges made at our factory.



The US, Europe, Russia, Turkey, Malaysia, the UAE, Saudi Arabia, Iran, Brazil, Chile, Mexico, South Africa, Jordan, Tunisia, Vietnam, Indonesia, Thailand, Singapore, Colombia, and Sri Lanka are just a few of the nations and territories to which our items are frequently transported.
