BX Ring Type Joints (also known as BX gaskets or API BX
ring gaskets) supplied by AMG Sealing are precision-engineered metallic
RTJ seals designed for ultra-high-pressure flange connections. These
specialised sealing rings are used exclusively with
API BX flanges and BX groove designs, where extreme
pressure containment and absolute sealing integrity are required.
Designed for demanding service conditions, BX Ring Type Joints are
suitable for pressures up to 20,000 psi, making them one
of the highest-rated metal-to-metal sealing solutions used in modern oil
& gas and subsea applications.
The BX gasket features a
square cross-section with bevelled corners, engineered to
create controlled deformation under load. The average diameter of the ring
is slightly larger than the BX flange groove, meaning that when installed,
it is forced into the groove and becomes pre-compressed. This generates
extremely high seating stress, resulting in a highly reliable,
pressure-energised seal ideal for critical service applications.
Applications of BX Ring Type Joints
BX Ring Type Joints are used in high-risk, high-pressure systems where
sealing failure is not acceptable. Typical applications include subsea
wellheads, blowout preventers (BOPs), drilling equipment, high-pressure
valves, pressure vessels, and offshore oil & gas installations
operating under extreme conditions.
