RX Ring Gasket
Cixi Jayu Sealing Materials Co.,Ltd is one of the leading China rx ring gasket manufacturers, welcome to wholesale cheap rx ring gasket, rx ring type joint gasket from our professional factory.RX Ring
Joint Gasket refers to the metal gasket of RX-shaped section by processing
metal materials. It is of pressure energized seal in radial direction, and the
pressure is up to 700bar. When the gasket is used, the outside seal face is
contacted with the flange firstly, and the high system pressure will produce
the high base stress. RX Ring Joint Gasket is developed
and improved in the basis of "R" series metal ring gasket and is 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. RX Ring 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. RX Ring
Joint Gasket is one kind of pressure energized ring gaskets. Some sizes of RX Ring Joint
Gaskets should have the pressure hole through the ring cross section. Cutaway View of RX Ring Joint
Gasket and Flange as follows *A plus
tolerance of 0.008 inches 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.RX Ring Joint Gasket is pressure energized, that is to say the higher the pressure is, the better
the seal performance is; 2.RX Ring Joint
Gasket is used in 6B flanges, it has the line seal with good seal performance, but it should
have high accuracy; 3.RX Ring Joint Gasket is of self-sealing. It
can increase the self-seal effect and prevent the gasket failure due to the
well pressure change and the shock in pressure test; 4.RX Ring
Joint Gasketcan be used interchangeably with 'R' metal ring gasket; 5.RX Ring
Joint Gasket can be reused in the field in the case of the appearance with no damage; 6.The hardness of RX
Ring Joint Gasket must be15~20HB lower than the mating flange face hardness; 7.The seal faces of
RX Ring Joint Gasket, including the bevel faces, shouldn't have the scratches,
knock marks, cracks and defects. Its surface roughness shouldn't be larger than
Ra1.6. Performance

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

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.
