Socket Weld / SWRF Flanges are designed with a shoulder inside the flange that guides the pipe into position before welding. This ensure proper alignment and a tight seal. The pipe is inserted into the socket and joined with a fillet weld around the top. These flanges are most often used in small-diameter, high-pressure piping systems. The raised face design improves the seal and flow, while the small gap between the pipe and flange reduces stress. Tesco Steel & Engineering is an SWRF Flanges manufacturer known for providing high-quality flange socket weld solutions. We provide durable pipe flanges to both domestic and global industries.
SWRF Flanges come in a wide range of sizes from 1/2″ (15 NB) to 48″ (1200 NB), with pressure classes including 150 to 2500 LBS. Common materials include carbon steel, stainless steel, alloy steel, duplex steel, nickel alloy, and copper. A socket weld flange is the type of connection—the pipe fits into a socket and is welded. A raised face flange refers to the small lip around the flange face that allows for better sealing.
These flanges are trusted across many sectors due to their strength, easy installation, and leak resistance. Industries like oil and gas, water treatment, chemical processing, and power generation use flange SWRF in critical applications. Their solid build and simple welding process make them suitable for high-pressure and corrosive environments. For pipelines, refineries and industrial plants, SWRF Flanges offer dependable performance under demanding conditions.
