Ferrobend manufactures and supplies premium quality Raised Face Threaded Flanges (RF) designed for reliable, secure, and leak-resistant connections in industrial piping systems. Featuring a raised gasket seating surface and precision-machined internal threads, RF Threaded Flanges enable convenient connection to externally threaded pipes without welding, making them suitable for oil & gas, petrochemical, chemical processing, water treatment, and general process piping applications where welding may be restricted or undesirable.
A Raised Face Threaded Flange (RF Threaded Flange) is a weld-free pipe flange featuring precision-machined internal threads that allow it to be directly screwed onto a threaded pipe. It is commonly used in piping systems where welding is impractical, undesirable, or restricted, subject to the applicable piping code, pressure, temperature, and service requirements.
The raised face (RF) provides a defined gasket seating surface for reliable sealing when properly assembled. With its weld-free connection and easy installation, Raised Face Threaded Flanges are suitable for utility piping, air lines, water services, and other industrial piping applications requiring convenient installation and maintenance.
Provides a practical weld-free connection where hot work is restricted.
Threaded design simplifies assembly, maintenance, and replacement.
The raised face (RF) provides a defined gasket seating surface.
Commonly used in utility lines, instrumentation, air, and water services.
Avoids direct pipe welding and can simplify fabrication for suitable applications.
Raised Face Threaded Flanges are preferred where welding is impractical, restricted, or undesirable, particularly in smaller-diameter and non-critical piping systems. Their weld-free threaded connection allows convenient installation and removal, while the raised face gasket seating surface supports reliable sealing when properly assembled.
The Raised Face Threaded Flange (RF Threaded Flange) is designed for weld-free pipe connections, easy installation, and reliable mechanical performance. It features precision-machined internal threads that engage directly with a threaded pipe, eliminating the need for a welded connection.
The raised face (RF) is precision machined to provide a defined gasket seating surface for reliable sealing when properly assembled. Manufactured using controlled forging processes where specified, the flange provides excellent mechanical strength and durability. CNC machining ensures accurate threading, bolt hole positioning, dimensions, and surface finish.
This precision construction provides:
