FAQ's
Ring Type Joint (RTJ) Flanges are high-pressure flanges
designed with a machined annular groove that accommodates a metallic
ring gasket. The ring gasket creates a metal-to-metal seal and provides
reliable performance in high-pressure and high-temperature piping systems.
Common RTJ flange configurations include:
- RTJ Weld Neck Flanges
- RTJ Blind Flanges
- RTJ Slip On Flanges
- RTJ Orifice Flanges
- RTJ Long Weld Neck Flanges
- RTJ Spectacle Blind Flanges
RTJ Flanges are commonly used in high-pressure and
high-temperature applications, including oil and gas,
petrochemical, refineries, power generation, pressure vessels,
and critical process piping systems where reliable sealing is required.
RTJ Flanges are manufactured in a range of materials depending on
pressure, temperature, corrosion resistance, and service requirements.
Common materials include:
- Carbon Steel
- Stainless Steel
- Alloy Steel
- Duplex Stainless Steel
- Nickel Alloys
RTJ Flanges provide a reliable metal-to-metal sealing
arrangement using a metallic ring gasket seated in a
precision-machined groove. This design offers excellent sealing
performance and is well suited for critical piping systems exposed
to high pressure, high temperature, and demanding operating conditions.
