1. Sealing Principle:
RTJ Gasket: Creates a tight, metal-to-metal seal by being compressed into a precision-machined groove in the flange.
Other Gaskets (e.g., Spiral Wound, Sheet): Create a seal through bolt compression, which deforms the gasket material to fill the flange face imperfections.
2. Design & Installation:
RTJ Gasket: A solid, heavy metal ring (often oval or octagonal) that sits in a groove, requiring specially designed RTJ flanges.
Other Gaskets: Typically flat sheets or rings placed directly between flat or raised-face flanges.
3. Pressure & Temperature:
RTJ Gasket: The superior choice for extreme service—very high pressure, high temperature, and high mechanical load.
Other Gaskets: Generally suited for low to medium pressure and temperature applications.
4. Seal Tightness:
RTJ Gasket: Provides a leak-proof, pressure-energized seal that becomes tighter as system pressure increases.
Other Gaskets: More prone to creep relaxation and potential leakage under severe cyclic conditions.
In summary: Choose RTJ gaskets for critical, high-performance applications like oil & gas, and refinery systems. For standard industrial uses, other gasket types are often sufficient.
There are many types of RTJ gaskets, including R Gasket,RX Gasket,BX Gasket, SBX Gasket,IX Gasket,and various customized products.We will do more sharing about ring joint gasket.
