STABILIZING FACE RING JOINT FLANGE AND ASSEMBLY THEREOF
In various embodiments, the stabilizing face ring joint flange and assemblies thereof can be adapted to include a ring joint gasket and resist leaks when a fluid flowing through a pipe at high temperatures and pressures. The stabilizing face ring joint flange assembly with the ring grooves in each flange can be situated in such a way that once full compression is achieved on the ring groove by the gasket, raised faces of the two flanges can meet to ensure that the rotation of the pump or any potential perpendicular loading do not provide a stress on the gasket that would cause the gasket to deform or cause a seal to be lost.
