Credibility ,Style RX RTJ gaskets are a pressure-energized adaptation of the standard Style R gasket. The RX is designed to fit the same groove design as a standard Style R, making the joints interchangeable. The modified design uses a pressure-energized effect that improves the efficiency of the seal as the internal pressure of the system increases.
Tolerances:(Inches)
Width of Ring ........................................+0.008,-0.000
Height of Ring .......................................+0.008,-0.000
(A plus tolerance of 0.008 inches for width and height is permitted, provided the variation in width or height does not exceed 0.004 inches throughout its entire circumference)
OD of Ring ............................................±0.020,-0.000
Angle of 23°…………................................±1/2°
Note: Only Rings RX82 through RX91 have a pressure passage hole through the cross section. Center line of hole is located on the mid-point of the width flat.
Hole diameter shall be as follows:
RX82 through RX85...............................0.06”
RX86 and RX87......................................0.09”
Rings RX88 through RX91......................0.12”
Style BX ring joint pressure energized 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 gasket allows virtual surface-to-surface contact of the flange faces, which means that the gasket is fully trapped on both the inner and outer diameters.
All BX gaskets 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.
