Ferrobend manufactures and supplies premium quality Raised Face Blind Flanges (RF) designed for reliable, secure, and leak-resistant closure of industrial piping systems. Featuring a raised gasket seating surface and solid blind construction, RF Blind Flanges provide reliable sealing, dimensional accuracy, and long-term performance across oil & gas, petrochemical, chemical processing, water treatment, and process piping applications.
The raised face (RF) provides a defined gasket seating surface that concentrates bolt load over the gasket area to support reliable pressure sealing when properly assembled. Raised Face Blind Flanges are widely used in high-pressure, high-temperature, and critical industrial piping systems, including oil & gas, petrochemical, chemical processing, and power generation applications.
Securely closes piping openings for maintenance, testing, and system modification.
The raised face provides a defined gasket seating surface for a reliable pressure-tight connection.
Forged construction provides excellent durability and structural integrity.
Can be removed when access to the pipeline or equipment opening is required.
Raised Face Blind Flanges are preferred for reliable pipeline isolation and closure of piping, valve, and pressure vessel openings. Their solid construction and bolted connection provide a robust pressure boundary, while the raised face gasket seating surface supports dependable sealing when properly assembled. Available in various pressure classes and material grades, they are suitable for demanding industrial piping systems where safe isolation, maintenance access, and long-term reliability are important.
The Raised Face Blind Flange (RF Blind Flange) is engineered to provide reliable pressure containment, sealing, and structural strength in demanding industrial piping systems. Its solid forged construction provides high mechanical strength, while the absence of a bore allows the flange to securely close and isolate a piping or equipment opening.
The precision-machined raised face provides a defined gasket seating surface for reliable sealing when properly assembled. After forging, CNC machining ensures accurate bolt hole alignment, dimensional tolerances, bore-free face geometry, and the required sealing surface finish. Where specified, heat treatment helps achieve the required mechanical properties for the selected material grade.
This robust construction makes Raised Face Blind Flanges suitable for high-pressure and high-temperature piping applications, including oil & gas, petrochemical, chemical processing, and power generation systems.
