Style BX pressure energized Ring Joint Gaskets are manufactured in accordance with API 6A and are designed for use on pressurized systems up to 20,000 PSI.
When correctly fitted, the style BX Ring Joint Gasket allows virtual surface-to-surface contact of the flange faces, which means that the Ring Joint Gasket is fully trapped on both the inner and outer diameters.
All BX Ring Joint Gasket incorporate a pressure balance hole to ensure equalization of pressure that may be trapped in the grooves.
Tolerances: ( Inches)
Width of Ring …………………………………+0.008,-0.000
Hole Size ……………………………………….±0.02
Height of Ring ………………………………..+0.080,-0.000
OD of Ring ……………………………………..+0.000,-0.006
Angle of 23° …………………………………..±1/4°
One pressure passage hole required per ring on centerline. A plus tolerance of 0.008 inches for width of ring and height of ring is permitted, provided the variation in width or height does not exceed 0.004 inches throughout its entire circumference.
NOTE: Radius of the ring shall be 8% to12% of the ring height.
