Socket Weld Flanges – Carbon & Stainless Steel, ½” to 48”, PN & ANSI Classes

These Socket Weld Flanges are engineered for secure and leak-proof connections in high-pressure piping systems. Manufactured from carbon steel (A105, ASTM A234, SS400) and stainless steel (SS304/L, SS316/L), they are designed for pipe sizes ranging from ½” (15 NB) to 48” (1200 NB). Socket weld flanges are ideal for small-bore piping and critical applications where strong, durable welds are necessary. They are available in a full range of pressure classes including PN6 to PN40, and ANSI 150 to 1500 lbs, complying with international flange standards. These flanges are typically used in refineries, chemical plants, and high-pressure steam or gas lines.
