RTJ Ring joint gaskets

Ring joint gaskets are purely metallic seals with high dimensional accuracy and surface quality and are used in operating environments with highest pressures and extreme temperatures. Their finely machined surfaces are free of scratches or other recesses and guarantee an extremely high sealing effect.

Ring joint gaskets in accordance with API and ASME standards are mainly used in the petrochemical industry and in refineries as a reliable gasket for production pipelines.

Type HST-RTJ-OV
 
Ring joint gasket with oval circular surface
  • circular sealing surface

  • sealing surface pressure increases to a lesser extent in response to the increase in the bold force

Type HST-RTJ-OC
 
Ring joint gasket with octagonal surface
  • gasket acts as a spherical gasket, thereby creating a larger contact or sealing surface

  • sealing surface pressure increases proportionally to the increase of the bolt force

Type HST-RTJ-BX
Ring joint gasket with flat sealing surface type BX 
  • pre-compressed gasket creates a high sealing value

  • sealing surface pressure increases proportionally to the increase of the bold load

Type HST-RTJ-RX
 
Ring joint gasket with flat sealing surface type RX
  • sealing effect increases with the increasing inner pressure of the medium

  • sealing surface pressure increases proportionally to the increase of the bold load
