The Style BX energized Ring Type Joints,manufactured in accordance with ASME B16.20, API 6A and API 17D, are designed for use on API 6BX flanges on pressure systems rated up to 20,000 psi.
When correctly fitted, the style BX gasket allows virtual face to face contact of the flange faces which means that the gasket is fully confined on both the inner and outer diameters.
All BX gaskets incorporate a pressure balance hole to ensure equalization of pressure which may be generated in the grooves.
Designs are also available for subsea applications.
Maximum surface finish of the Style BX Ring Type Joint sealing faces (23° angled faces) shall not be greater than 0.8 μm Ra / 32 μin RMS.
