Precision Ring Type Joint Gaskets
This type of gasket is designed to be used in RTJ groove flanges and are produced under license to dimensions as per API-6A and ASME B16.20.
Technical Details:
- Ring Type Joints concentrate the bolt load over a small area producing high sealing stresses.
- As the Ring Type Joint Material should always be softer than the mating flanges, the high seating stress causes ”plasticflow” of the ring joint in the flange faces creating the seal.
- RTJ Gaskets can be produced from a variety of material’s to suit the process application and flange grade.
- Used on high pressure lines up to 20,000 PSI, RTJ’s are an extremely reliable and robust sealing mechanism.
- BX, SBX & RX type available for Sub Sea application.
- IX Seal Rings used in Norsok Compact flange assemblies.
- Standard R type available R11 (1/2”) to R105 (36”) in Oval or Octagonal Section.
