Style RX type RTJ gaskets are manufactured in accordance with both API 6A and ASME B16.20 to suit API 6B and ASME/ANSI B16.5 flanges.
Style RX is 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 pressureenergized effect that improves the efficiency of the seal as the internal pressure of the system increases.
Pressure: 5,000-20,000 PSI
| TOLERANCES:(mm)A*(width of ring) +0.20,-0.000 A*(hole size) ±0.5 H*(height of ring) +0.20,-0.000 OD(od of ring) +0.000,-0.150 23*(angle) ±1/4° |
NOTE 1: Radius of the ring shall be 8%to12% of the ring height ‘H’.
One pressure passage hole required per ring on centre line *A plus tolerance of 0.008inches for width *A* and height *H* is permitted. provided the variation in width or height does not exceed 0.004 inches throughout its entire circumference
Designs are also available for Subsea applications.
