It is made of solid metal forgings. Suitable for high pressure and high temperature working conditions. The seal of the ring joint gasket uses a very high unit load to create a metal-to-metal wire seal between the ring and the flange sealing surface.
The material of the ring joint gasket shall be softer than the flange sealing surface to avoid the damage of the gasket to the
flange sealing surface. The design of the gasket or the section shall be selected with the structure of the flange sealing surface and the maximum design system pressure value. In order to achieve and maintain an effective seal, the accuracy of the gasket and flange sealing surface, the dimensional accuracy and the hardness of the gasket must be carefully controlled.
Ring Joint Gasket (RTJ) information:
· All gaskets have permanent low stress steel marks, identification type, ring number, materials and standards
· All gaskets are in full compliance with ASME B16.20, API 6A specifications or other applicable standards
· All gasket raw materials are fully traceable and relevant documentation is available
· Precise control of the ring joint gasket material hardness to ensure the sealing performance, while avoiding damage to the flange sealing surface
·With the correct selection of the gasket material, the ring joint gasket can seal harsh chemical media and high temperature conditions of 1,000°C (1,832°F)
Gasket Type
Type DH-RJ- R | 1,R type, The ring cross-section can be oval and octagonal 2,Standard sizes can be manufactured per ASME B16.20, API 6A specification or other applicable standards |
|
Type DH- RJ-RX | 1,The RX type RTJ has its unique self-sealing properties. The inclined plane on the outside of the ring contacts the outer ring surface of the RTJ flange groove to form a seal. When the internal pressure increases, the gasket load increases the stress generated by the flange grooves correspondingly, which further enhances the sealing effect 2,The design features of RX type RTJ make it more suitable for impact load, test pressure impact and drilling vibration conditions |
|
Type DH- RJ-BX | 1,The joint diameter of the BX RTJ is slightly greater than that of the RTJ flange groove. This design allows the ring pad to make contact with the outer ring surface of the groove. Preloaded spacers produce self-tight seals |

GENERAL NOTES:
(a) All dimensions are in millimeters.
(b) Radius, R, shall be 8% to 12% of the gasket height, H.
(c) Tolerances:
A = width of ring, +0.20, −0.00
Variation in width throughout the entire circumference of any ring shall not exceed 0.10 within these tolerances.
C = width of flat, +0.15, −0.00
D = hole size, ±0.5
H = height of ring, +0.20, −0.00
Variation in height throughout the entire circumference of any ring shall not exceed 0.10 within these tolerances.
OD = outside diameter of ring, +0.00, −0.15 ODT = outside diameter of flat, ±0.05
R = radius of ring [see General Note (b)] 23 deg p angle, ±0 deg 15 min.
NOTE:
(1) One pressure passage hole is required per gasket as illustrated. The centerline of the hole shall be located at the midpoint of dimension C.
