Slip-On Raised Face (SORF) flanges are widely used in piping systems to connect pipes for efficient flow and pressure control. These flanges are known for their easy design, which makes it simple to install using bolting or welding without the need for complicated equipment or procedures. A SORF flange includes two raised faces, a hub bore, and bolts or studs to secure the joint, ensuring strong alignment and connection. Tesco Steel & Engineering is a leading SORF Flanges Manufacturer offering a wide range of Flat Face (FF), Raised Face (RF) and Ring Type Joint (RTJ) designs. They come in pressure classes like as 150 LBS, 300 LBS and 600 LBS, and sizes range from 1/2′′ (15 NB) to 48′′ (1200 NB). As SORF flanges are available in a range of sizes and ratings, they can be used in a variety of industries.
The difference between SORF and SWRF flanges lies mainly in the welding method. Although they are both slip-on varieties, Socket Weld Raised Face (SWRF) flanges, use a socket weld connection, whereas SORF flanges are welded using a fillet weld on both sides. This makes SWRF more suitable for high-pressure applications. SORF is better for low to moderate pressure systems where quick installation and cost savings matter more.
SORF flanges are known for their easy setup, leak-proof connection, and cost-effectiveness. They resist corrosion and work well in low to mid-pressure setups. These flanges are often used in oil and gas pipelines, where pressure and safety are critical. In chemical plants, SORF flanges help seal joints against toxic leaks. In water industries, they’re ideal for transporting saltwater and fuel oil due to their rust-resistant properties. They are used in the food industry to keep sealed, hygienic systems. Due to their strong connections and ease of maintenance SORF flanges are also advantageous for HVAC and plumbing systems.
