Ring Joint Gasket Advantages And Disadvantages
Advantages
- Ring type joints are utilised for high pressure sealing up to 20,000 psi.
- To meet the process application and flange grade, RTJ Gaskets can be manufactured from a range of materials.
- RTJs are exceptionally dependable and durable seals.
Disadvantages
- Because of the plastic flow of the ring joint in the flange faces to create the seal, ring-type gaskets are unsuitable for reuse.
- When compared to other types of gaskets, it is highly pricey.
- Skilled labour is necessary for successful installation.
Can Ring Joint Gaskets Be Reused
Ring joint gaskets are made with a limited amount of positive interference to guarantee that the ring type joint seats appropriately into the groove when compressed. Their re-use is not advised for two reasons:
- The gasket's initial seating will be hampered.
- Work hardening of the exterior metal surface happens when the gasket is plastically deformed. This could cause lasting damage to the groove.

How To Install Ring Joint Gasket
The axial compressive load (from bolt tightening) acts on the Ring type joint (RTJ) gasket, causing it to distort and flow into flange groove imperfections. As a result, metal-to-metal contact has established between the gasket and the flange, forming a seal.
The ring-type joints are extremely tight and resistant to temperature and pressure changes. When installing a ring-type joint gasket, pay particular attention to the bolting up to ensure uniform load operating on the gasket. Also, ensure that the RTJ gasket and groove faces are free of flaws and debris.
