Blowout Preventer Gasket
Cixi Jayu Sealing Materials Co.,Ltd is one of the leading China blowout preventer gasket manufacturers, welcome to wholesale cheap blowout preventer gasket, bop ring gasket from our professional factory. BX ring type joint gasket refers to the metal gasket of BX-shaped
section by processing metal materials. It is of pressure energized seal in
radial direction, one special kind of octagonal metal ring gaskets. It has good
sealing as the contact between gasket and the ring joint faces, especially the
outside face, and is pressed tightly to keep good sealing performance. BX ring type joint
gasket is installed inside the ring
joint groove of flange face. When the connecting bolt is fastened, it is
compressed in axis direction and is pressed close to the upper and lower ring
joint grooves, which result in the plastic deformation to create the seal.
After pressure is raised, the ring gasket expands in radial direction under the
force of media pressure. The gasket sticks more tightly to the bevel face of
ring joint groove to form self-tightening. However, the rise of media pressure
will deform the flange and connecting bolt, it will cause the relative
separation between the sealing surfaces, and the sealing ratio of gaskets is
reduced accordingly. BX ring type joint gasket is one kind of pressure
energized ring gaskets. Some sizes of BX ring type joint gaskets should
have the pressure hole through the ring cross section. Cutaway View of 'BX' Steel Ring and Flange
as follows One pressure passage hole required per ring on
center line *A plus tolerance of 0.2 mm for width 'A' and height 'H' is permitted, provided the
variation in width or height does not exceed 0.1 mm throughout its entire
circumference Features 1.BX ring type joint gasket can only be used in 6 BX
flanges ; 2.BX ring type joint
gasket t is pressure
energized, that
is to say the higher the pressure is, the better the seal
performance is;3.BX ring type joint
gasket is used
in 6 BX flanges, it has the line seal with good seal performance,
but it should have high accuracy; 4.BX ring type joint gasket can not be used interchangeably with other
styles of gaskets��5.BX ring type joint gasket can only be used for one time; 6.The hardness of BX ring type joint gasket
must be15~20HB lower than the mating flange face hardness; 7.The seal faces of 'BX' metal ring gasket,
including the circle and chamfer, shouldn't have the scratches, knock marks,
cracks and defects. Its surface roughness shouldn't be larger than Ra0.8. Performance Parameters gasket

gaskets are primarily used in the oil, gas, petrochemical and offshore
industries. They are also commonly used on valves, pipe-work assemblies and
vessel joints and are used to seal flanged connections subject to high
pressures and temperatures. Technical
Standards It can
provide any standard and non-standard sizes, including the standards of API 6A,
API 17D, ASME B16.20, DIN 2693-67, JPI-7S-23-72 and other standards. More informations, please click the "PDF" download or contact with us. Click here to download the Jayu Bx Ring Type Joint Gaskets product guide pdf.
