Steelage Alloys is one of the leading Raised Face SS Flange dealers in India, offering high-quality stainless steel flanges that meet global standards of performance, strength, and corrosion resistance. As a trusted supplier in the stainless steel industry, we provide a complete range of Raised Face (RF) flanges in various grades, sizes, pressure ratings, and face types to meet the diverse needs of our industrial clients.
Our RF flanges are manufactured using premium-grade stainless steel such as SS 304, SS 316, 316L, 321, and Duplex—ensuring durability in harsh operating conditions across oil & gas, chemical, petrochemical, water treatment, and power generation sectors.
A Raised Face (RF) flange is one of the most common types of flanges used in process piping systems. It features a slightly raised surface around the bore, where the gasket is placed. This raised surface helps to concentrate more pressure on a smaller gasket area, enhancing the sealing performance between two flanged connections.
Raised face flanges are ideal for high-pressure and high-temperature applications. They are compatible with various gasket types such as spiral wound, ring type, or full face.
