Socket Weld Flanges are forged fittings designed for small-diameter, high-pressure pipelines. These flanges offer a static connection between the pipe and flange using a socket-type weld joint. At Turnon Alloys, we produce precision-engineered flanges that meet demanding specifications across industries such as petrochemical, power generation, and oil and gas. The design allows for smooth fluid flow and minimizes turbulence, making it a preferred solution for compact piping layouts.

A Socket Weld Flanges Stockists provides flanges with a recessed shoulder where the pipe sits before being fillet welded around the hub. This socket-type weld ensures a secure connection suitable for applications requiring high integrity and tight tolerances. Turnon Alloys ensures all flanges meet ASTM A182 and ASME B16.5 standards, maintaining quality and performance. These flanges are commonly used in systems that don’t require frequent disassembly, supporting both fluid and gas transfers under pressure.
One of the biggest advantages of Socket Weld Flanges is their ability to handle high-pressure services while reducing the risk of leakage. Because of the internal socket, pipe alignment is easier, improving weld quality and reducing welding time. As trusted Socket Weld Flanges Suppliers, Turnon Alloys offers corrosion-resistant grades like ASTM A182 F304, F316, and F321, suitable for both aggressive and standard environments. These grades ensure long service life and structural integrity under various operational conditions.
In international markets, Socket Weld Flanges go by different terminology but maintain the same functionality. In Germany, they are often called “Socketanschlussflansche”; in Japan, they’re known as “Soketto uerudo furanji”; in France, “Brides à emboîtement”; in the Middle East, they are referred to as “Socket Weld Type Flanges.” Turnon Alloys supplies globally, making us your trusted Socket Weld Flanges Stockists with full traceability and MTCs provided as per EN 10204 3.1.
Turnon Alloys adheres to global piping standards. Here's how socket weld flanges correspond to international piping codes: ASTM A182 / ASME B16.5 – United States, EN 1092-1 – European Union, JIS B2220 – Japan, GOST 12820-80 – Russia, BS 4504 – United Kingdom, DIN 2573 / 2576 – Germany We provide custom marking and stamping for compliance across these standards.
