> Although similar in style to the octagonal ring joint > BX series can only be used with 6BX flanges > BX rings for higher pressure rating starting at 5,000 lbs, and ending with 20,000 lbs. > BX Ring Joint Gasket can not be re-used.
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 gasketis installed inside the ring joint groove of flange face. When the connecting bolt is fastened, it is compressed
in axis direction andispressed close to the upper and lower ring joint grooves, which result in the plastic deformation to create the seal.
After pressure is raised, ring gasket expandsin radial direction under the force of media pressure. The gasket sticks more tightly to the
bevel face of ring joint groove to formself-tightening. However, therise of media pressure will deform the flange and connecting bolt, it
will cause the relative separation between the sealingsurfaces, and the sealing ratio ofgaskets is reduced accordingly. BX ring type
joint gasket is one kind of pressure energized ring gaskets.
Note: When octagonal type is chosen, the material hardness of the pad should be 15~20HB lower than that of the flange face. It is
recommended the pad is not recycled.
