Flange Threaded Raised Face (THRF)

A Threaded Raised Face (THRF) flange is a type of flange with internal threads that allow it to be screwed onto a pipe or fitting. It features a raised face around the bore, which enhances the sealing performance by compressing the gasket more effectively when the flange is tightened. THRF flanges are typically used in applications where welding is not feasible or where ease of disassembly is important. They are commonly used in low to medium pressure applications and are suitable for various industries, including water treatment, chemical processing, and HVAC systems.
