The Style RX is an adaptation of the standard Styler which is energized when the assembly is pressurized. The RX is designed to fit the same groove design as a standard Style R, making the joints inter changeable, however consideration should be given to the difference in finished make up distance. The geometry of this modified design induces a pressure energizing effect when the assembly is pressurized, improving the efficiency of the seal. Designs are also available for subsea applications on existing assets, however, current API17D does not support use of SRX ring type Joints.
