Ring Type Joint Gaskets

“RTJ” (Ring Type Joint) gaskets are manufactured in accordance with API-6A, API-17D and ASME B16.20  specifications. RTJ’s have “R, RX and BX” numbers assigned to them for pipe size and pressure class identification. Stock materials include Soft Iron, Low Carbon Steel, F5, F11, F9, 304, 304L, 316, 316L, 321, 347, DUPLEX, Monel, NICKEL, 410, Inconel and Incoloy. RING JOINT GASKETS are precision machined metallic sealing rings, suitable for high temperature and high pressure applications. By applying pressure to the seal interface through bolt force, the softer metal of the gasket flows into the micro-fine structure of the harder flange material, creating a very tight and efficient seal. They are available in several common profiles to suit a variety of industry standard flanges. Reliable rubber coated ring joint gaskets are made from precision machined carbon steel rings to API specifications and utilize a special metal-to-rubber bonding process of oil resistant nitrile rubber. Ideal for hydraulic testing of BOP’s (Blowout Preventers), Christmas Trees, Chokes & Kill Manifolds and available in most of the commonly utilize sizes of R and BX series rings. Rubber Coated Ring Gaskets are used to minimize the risk of fl ange damage during testing and should be removed and replaced with specified gasket for actual application. Ring type joints are primarily used by the oil, gas and petrochemical and offshore industries. They are also commonly used on valve/pipework assemblies and high integrity vessel joints.

Ring Type Joints are used to seal flanged connections subject to high pressures and temperatures. These precision made solid metal gaskets form a metal-to-metal seal with the flanges. Precision Machine Tools manufactures large range ring gaskets in accordance with API-6A/ASME 16.20. We manufacture four basic types of ring gaskets; octagonal shape, oval shape, type RX and type BX. These basic shapes are used in pressures up to 20,000 psi. The dimensions are standardized and require specially grooved flanges. The octagonal cross section has a higher sealing efficiency than the oval and would be the preferred gasket. Stock materials include soft iron, low carbon steel, 4-6 chrome (F5), 304, 316,   Inconel and Incoloy. 

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.They are widely used in the Oil/Gas and Petrochemical industry, in valves and pipe-work. Choice of material may be determined to suit higher temperatures and aggressive media. They comply with ASME B16.20 standards and API spec 6A (where applicable).
