Product Description
Ring Joint Gaskets:
Ring type gaskets are primarily used in the Oil, Gas and Petrochemical industries to seal flanged connections subject to high pressure and temperatures, and form a metal to metal seal with the flanges. The gaskets fully comply with the ASME B16.20 standard and the API spec 6A requirements (where applicable). All gaskets complying to API Standard 6A are marked with API Monogram Licence No as per API-6A (PSL4). The gaskets meet the rigid quality requirements for Ring Joint Gaskets set by the American Petroleum Institute (API).
Materials includes Soft Iron, Low Carbon Steel, F5 Alloy Steel, 410 Alloy Steel, SS304, SS304L, SS316, SS316L, SS347, SS321, Nickel Alloy 625 & 825, Duplex, Super Duplex, Monel & other materials available.
Rilson RTJ gaskets are manufactured in accordance with API-6A and ASME B16.20 specifications and come in four basic profiles:
R type (oval and octagonal) solid sections to fit standard ring joint flanges with trapezoidal grooves.
Types RX and BX with complex bevelled edge sections for wellhead pressures exceeding 700bar
These basic shapes are used in a variety of applications with pressures up to 20, 000 PSI. The dimensions are standardized and require specially grooved flanges by where a corresponding "R" or "BX" number is assigned for pipe size and pressure class for gasket identification.
