 Ring Type Joint FlangesRing Type Joint Flanges 

Ring-Type Joint (RTJ) The Ring Type Joint flanges are typically used in high pressure (Class 600 and higher rating) and/or high temperature services above 800°F (427°C). They have grooves cut into their faces which steel ring gaskets. … An RTJ flange may have a raised face with a ringgroove machined into it.RF flanges seal with a flat gasket, formerly made of asbestos but now made of more environmentally friendly material, designed for installation between the raised faces of two mating flanges (both with raised faces). The raised faces have a prescribed texture to increase their gripping and retaining force on this flat gasket.

RTJ flanges have grooves cut into their faces which accept steel Ring Gaskets. RTJ flanges seal when tightened bolts compress the gasket between the flanges into the grooves, deforming (or “Coining”) the gasket to make Intimate Contact inside the grooves, creating a metal to metal seal.

NOTES:

(1) The height of the raised portion is equal to the depth of the groove dimension, E, but is not subjected to the tolerances for E. Former full-face contour may be used.

(2) For ring joints with lapped flanges in Classes 300 and 600, ring and groove number R30 is used instead of R31.
