BX ring type joint gasket refers to the metal gasket of BX-shaped
section by processing metal materials. It is of pressure energized seal in
radial direction, one special kind of octagonal metal ring gaskets. It has good
sealing as the contact between gasket and the ring joint faces, especially the
outside face, and is pressed tightly to keep good sealing performance.











BX ring type joint
gasket is installed inside the ring
joint groove of flange face. When the connecting bolt is fastened, it is
compressed in axis direction and is pressed close to the upper and lower ring
joint grooves, which result in the plastic deformation to create the seal.
After pressure is raised, the ring gasket expands in radial direction under the
force of media pressure. The gasket sticks more tightly to the bevel face of
ring joint groove to form self-tightening. However, the rise of media pressure
will deform the flange and connecting bolt, it will cause the relative
separation between the sealing surfaces, and the sealing ratio of gaskets is
reduced accordingly. BX ring type joint gasket is one kind of pressure
energized ring gaskets.


Some sizes of BX ring type joint gaskets should
have the pressure hole through the ring cross section.
