RTJ Flanges, Ring Type Joint Flange
A metal ring is compressed into a hexagonal groove on the face of the flange to make the seal. This jointing method can be employed on Weld Neck, Slip-on and Blind Flange.
Ring Type Joint Flanges (RTJ) or Ring Joint Facing Flanges (R-JF):
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.
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 BX ring gaskets, the raised faces of the connected and tightened flanges may contact each other. In this case the compressed gasket will not bear additional load beyond the bolt tension, vibration and movement cannot further crush the gasket and lessen the connecting tension.
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.

RTJ steel flange 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.
Ring Type Joint gaskets
Ring Type Joint gaskets are metallic sealing rings, suitable for high-pressure and high-temperature applications. Pipe Fitting are always applied to special, accompanying flanges which ensure good, reliable sealing with the correct choice of profiles and material.
Specifications of Ring Type Joint Flange:
An RTJ steel 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 BX ring gaskets, the raised faces of the connected and tightened flanges may contact each other. 
In this case the already coined gasket will not bear additional load beyond the bolt tension, vibration and movement cannot further crush the gasket and lessen the connecting tension.
