What is RTJ in flanges and its advantages?

RTJ (Ring Type Joint) flanges are a type of flange designed for high-pressure and high-temperature applications. The RTJ face features a precision-machined groove where a metal ring gasket is placed. When the flange is bolted together, the gasket deforms to create a tight, metal-to-metal seal, ensuring excellent leak prevention.

Advantages of RTJ Flanges

1.Superior Sealing – The metal-to-metal contact ensures a reliable, leak-proof seal, even under extreme conditions.

2.High-Pressure Resistance – RTJ flanges are ideal for applications involving high pressure, making them common in the oil, gas, and petrochemical industries.

3.Temperature Endurance – The robust seal remains effective in both high and low temperatures, enhancing safety and performance.

4.Reduced Risk of Gasket Blowout – Unlike soft gaskets, metal ring gaskets in RTJ flanges are more resistant to blowouts, ensuring long-term reliability.
