A socket weld flange is a type of flange designed for use with high-pressure, small-diameter piping systems. It features a recessed area (or socket) into which the pipe is inserted before being welded around the outer edge, creating a strong and leak-proof connection. This design provides excellent structural integrity and is particularly suitable for applications involving high pressure and temperature. Socket weld flanges are commonly made from materials such as stainless steel, carbon steel, and alloy steel to meet the demands of various industrial environments. These flanges are ideal for systems where high leakage integrity and strength are critical, such as in chemical processing, oil and gas, power generation, and high-pressure steam lines.
