RF、FF、RTJ 法兰面和表面处理(中英文对照) - 百家号
2022年11月5日 · The flange face is the surface area that hosts the gasket. The 6 available types of flange face are flat (FF), raised (RF), ring joint (RTJ), lap joint, male and female (M&F), tongue and groove (T&G). Flanges with different faces require different gaskets and shall never be mated to prevent leakage of the joint.
Flange Faces - Raised Face (RF), Flat Face (FF), Ring-Type Joint (RTJ ...
An RTJ flange may have a raised face with a ring groove machined into it. This raised face does not serve as any part of the sealing means. For RTJ flanges that seal with ring gaskets, the raised faces of the connected and tightened flanges may contact each other.
RF Vs. RTJ Vs. Other Flange Faces: Key Differences
The main difference between RF and RTJ flanges and other flange face lies in their sealing mechanism, appearance, installation, requirement of maintenance and more. RF flanges typically used in systems with low or medium pressure and temperature areas.

Flange Faces Explained (Flat, Raised, etc) - saVRee
Ring-type joint (RTJ) flanges are a variation of the raised face flange design. RTJ flanges are typically used for more severe applications, particularly for high pressure systems, and/or high temperature systems (>750⁰C / 1,382⁰F). It is possible to use RTJ flanges across all pressure classes, but they are typically used for class 900 and above.
