Ferrobend manufactures and supplies premium quality Raised Face Slip-On Flanges (RF) designed for reliable and secure connections in industrial piping systems. Featuring a raised gasket seating surface and a slip-on design for easy pipe installation, RF Slip-On Flanges provide reliable sealing, dimensional accuracy, and long-term performance across general industrial, water treatment, oil & gas, and process piping applications.
A Raised Face Slip-On Flange (RF SO Flange) is a widely used pipe flange designed for applications where easy installation and reliable bolted connections are required. It has a slightly larger bore than the pipe, allowing the flange to slide over the pipe before being secured with internal and external fillet welds.
The raised face (RF) provides a defined gasket seating surface for reliable pressure sealing when properly assembled. With its simple construction and easy pipe alignment, the Raised Face Slip-On Flange offers a practical and economical solution for industrial piping systems, including water treatment, chemical processing, petrochemical, and general process services.
Slides over the pipe for convenient positioning and alignment.
The raised face provides a defined gasket seating surface for a dependable connection.
Offers economical fabrication and installation for many industrial piping applications.
Internal and external fillet welds secure the flange to the pipe.
Suitable for water treatment, chemical, petrochemical, and general process piping systems.
Raised Face Slip-On Flanges offer a practical combination of easy installation, reliable bolted connections, and cost-effective fabrication. Their simple design makes them widely used in industrial piping systems where moderate pressure and temperature conditions allow a Slip-On Flange connection.
The Raised Face Slip-On Flange (RF SO Flange) features a slightly oversized bore that allows the flange to slide over the pipe for convenient positioning and alignment before welding. Its precision-machined raised face provides a defined gasket seating surface, while internal and external fillet welds secure the flange to the pipe.
Manufactured from high-quality forged materials, the flange is precision machined to achieve accurate bore dimensions, bolt hole positioning, and face finish. Heat treatment, when specified, helps achieve the required mechanical properties and durability, providing a practical balance of strength, cost efficiency, and reliable performance for industrial piping applications.

Shaped by heating a solid billet and compressing it under high pressure, aligning the grain flow for superior strength and pressure resistance.
Billet progressively shaped by rotating rollers, giving a uniform grain structure and high fatigue resistance.
Machined directly from a flat metal plate without forging — a cost-effective option for low-pressure or non-critical applications.
Our products are tested and certified as per international quality standards with complete traceability and documentation.
