How does a RTJ flange work?
RTJ flanges can be sealed by RTJ gaskets of different styles and profiles. The general RTJ gasket is the R style with an octagonal section, as it places a very strong seal (the oval section is an older type). A “flat groove” design, however, accepts both RTJ gaskets having an octagonal or oval section. The seal of an RTJ gasket occurs under the force of closing the bolt and hardware after mating one flange to another. Typically, the gaskets are made of softer material than the metal of the flanges they are sealing. The most common of these materials is a soft iron. Slow and steady pressure on the hardware of the flange” crushes” the gasket within the ring joint surface. This helps to prevent any type of leakage during operation of the flange assembly.

Application: In refineries and petrochemical plants, ring-type joint (RTJ) flanges have been applied to high-pressure processes or sensitive areas that are susceptible to leaks. In an RTJ flange, the bolt tightening load should be calculated and applied carefully to achieve good sealing performance and to avoid flange deformation with over-tightening.
