SUNWELL's Ring Joint Gaskets are precision machined,metallic sealing ring suitable for high pressure and high temperature applications. RTJ gaskets are designed to seal by initial line contact or welding action between the mating flange and the gasket. By applying pressure on the sealing interface throngh bolt foce, the softer metal of the gasket flows into the micro-fine structure of the harder flange material,creating a very tight and efficient seal.

Application :

Standard:
Standard style R ring type joints are manufactured in accordance with both API 6A and ASME B16.20 size and ratings. Available in both oval and octagonal configurations, both types are interchangeable on the modern octagonal type grooved flanges.
As with all metal ring type joints including style R, it is recommended to replace the ring when flange connection is broken.
