Ring Type Joint Flanges Manufacturer & Supplier
Sawariya Metal Industries manufactures, supplies, stocks and exports Ring Type Joint Flanges (RTJ) for demanding industrial piping and process applications. RTJ Flanges are designed with a precision-machined annular groove that accommodates a metallic ring gasket to create a high-integrity sealing arrangement.
Ring Type Joint Flanges are commonly selected for applications where pressure, temperature and sealing requirements demand a robust flange connection. The controlled groove geometry and corresponding RTJ gasket provide a metal-to-metal sealing arrangement when correctly installed according to the applicable specification.
Our RTJ Flanges are available in different materials, sizes, pressure classes and dimensions according to project requirements. Applications include oil & gas, petrochemical, refinery, chemical processing, power generation, marine, nuclear, defence and industrial fabrication.
