DESCRIPTION

Atraseal Ring type joint flange gaskets (RTJ gaskets) are used in applications that involve extreme pressures and high temperatures. The gasket material ideally needs to be roughly 30 Brinell less than the flange Material to ensure sufficient deformation of the gasket without damaging the flange facing. All Atraseal ring type joint gaskets are manufactured in compliance with API-6A and ANSI B16.20 specifications. Whether you are looking for a standard ring type joint gasket or custom design assemblies, our team of application engineers have the product and application know-how to find the right solution for your specific application.


APPLICATION

Ring Joint gaskets are widely used between pipeline flanges, valves and pressure vessels in the Oil & Gas industry; Withstand high pressure situations up to 400 bar (pending on flange construction and rating); Style R gaskets are suitable for ASME B16.5 flanges up to 2500 lbs. API 6A type 6B flanges can withstand a pressure up to 5000 psi.


CHEMICAL COMPATIBLITY AND TEMPERATURE

Corrosion and chemical resistance depend on the selected RTJ gasket material. The temperature ranges can be found in the Technical Specifications, see table 1.


DELIVERY OPTIONS

Octagonal shaped RTJ gaskets are available in ring numbers R11 up to R105. Atraseal can produce custom made gaskets according to customer specifications.
