Product Data SheetApplication
Ring Joint gaskets are widely used between pipeline flanges, valves and pressure vessels in the Oil & Gas industry. High pressure up to 400 bar (pending on flange construction and rating) Style R gaskets are suitable for ASME B16.5 ring joint flanges up to 2500 lbs. In case API 6A type 6B flanges are used, pressure up to 5000 psi can be applied.
Chemical Compatiblity
Corrosion and chemical resistance depend on the selected RTJ gasket material. The pressure and temperature ranges can be found in the Technical Specifications, see table 1.
