Ring type joint gasket (RTJ Gasket) is a high integrity sealing gasket, high temperature and high pressure gasket for applications in petroleum industry, oilfield drilling, pressure vessels joints, pipes and valves etc from Goodrich Gasket Pvt. Ltd.
Goodrich Gasket manufactures ring joint gaskets (RTJ Gasket) according to API 6A and ASME B16.20 for numerous industrial applications based on the customer required specifications with corrosive protection using electroplated zinc or alternate material coating of up to 0.0003” thickness.
As a result of metal to metal sealing media they are made to be free of indentations, tool marks etc and have a surface finish of maximum,
- R, RX – 63 microinches Ra (1.6 micrometer Ra).
- BX – 32 microinches Ra (0.8 micrometer Ra).
The working of ring joint gaskets (RTJ Gasket) can be explained by the axial compressive load causing them to deform and flow to irregularities in the flange grooves that it seals. As load bearing area of ring joint gaskets (RTJ Gasket) are small high surface stresses are produced between the sealing face and the groove, making it poor in recovery characteristics and unfit for reuse.
Goodrich Gasket manufactures Type R, RX, BX ring joint gaskets (RTJ Gasket) in API 6A, ASME B16.20 gasket standards for API 6B, ASME B16.5 and API 6BX flanges respectively.
