Ring Type Joint Gasket (RTJ) is a sealing element specifically designed for high-pressure and high-temperature applications. It is typically manufactured from stainless steel, carbon steel, or alloy steel, precision-machined into ring shapes, and polished to achieve a smooth surface finish that ensures a tight fit with flange grooves.

Performance

  • Provides stable sealing under extreme pressure, temperature, and corrosive conditions
  • High resistance to crushing, ideal for high-pressure flange connections
  • Polished surface treatment to reduce leakage risk

Advantages

  • Excellent sealing reliability with extremely low leakage rate
  • Widely used in oil, gas, petrochemical, and power industries
  • Fully compliant with international standards such as API and ASME

Materials

Soft Iron, Carbon Steel, F5, ss304, ss304L, ss316L, s31803, Monel400, Inconel625, Inconel825, C276, Titanium

Specification

  • Hardness
    Softer than the mating flanges to ensure it can't not damage the groove
