What is Ring Type Joint (RTJ) gasket?

R Ring Gasket are available in oval and octagonal designs. We manufacture B18c Type R Gasket, R-24 Ring Gasket, R-49 Ring Gasket in India, Check price list of Type R Valve Cover Gasket in MumbaiThe Ring Type Joint (RTJ) gasket could be a solid ring that matches into the machined groove of an RTJ flange.

The ring type joint gaskets are either octagonal or oval in cross-sectional. RTJ gaskets are typically used for high pressure and high-temperature applications. It is widely used in refinery, petrochemical and oil field drilling industries. The Ring type joints gaskets are factory-made as per ASME B16.20. They are dimensionally suitable for use with flanges manufactured as per standards ASME B 16.5, ASME B16.47, and API 6A. The axial compressive load (due to bolt tightening) act on the Ring type joint(RTJ) gasket inflicting them to deform and flow into irregularities of projection grooves. Because of this, a metal-to-metal contact is formed between gasket and flange that makes a seal.

The ring sort joints have a superb tightness and tolerance to temperature and pressure changes. While putting in a ring type joint gasket terribly close attention should be given to their bolting up for uniform load functioning on the gasket. Also, confirm the RTJ gasket and groove faces should be freed from imperfections and scrap.

Ring Joint Gaskets Types

Style R
  • Available in oval and octagonal cross-sections
  • Style R gaskets are interchangeable on modern octagonal flat bottom grooved flanges
  • Standard sizes of Style R gaskets are manufactured in accordance with ASME B16.20 and API 6A specifications
Style RX
  • The Style RX ring joint has a unique self-sealing action. The outside bevels of the ring make the initial contact providing a seal against the grooves outer surfaces. As the internal pressure increases, so does the gasket loading stress against the groove thus improving the gaskets sealing characteristics
  • Design features of the Style RX gasket make it more resistant to shock load, test pressure shock and drilling vibration
  • Style RX ring joints are completely interchangeable with standard Style R groove designs. Care should be taken when interchanging these styles as RX gaskets are taller and will add length to the finished assembly
Style BX
  • Style BX gaskets have a pitch diameter slightly larger than the groove pitch diameter. This allows for initial contact to be made on the outside of the ring, pre-loading the gasket which creates a pressure energized seal
  • All Style BX gaskets incorporate a pressure passage to enable trapped pressure to balance itself in the joint
  • Style BX ring joint gaskets can only be used with API BX flanges and are not interchangeable with style RX
