For RTJ flanges that seal with ring gaskets, the raised faces of the connected and tightened flanges may contact each other. The newer flat bottom groove design will accept either the oval or the octagonal cross section. Threaded flanges are threaded in the bore which match an external thread on the pipe.

Further, the RTJ flange will be damage the gasket, especially if a spiral wound or metal jacketed gasket is applied.

One flange face has a raised ring Tongue machined onto the flange face while the mating flange has a matching depression Groove machined into it’s face.

The 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.
