01 What are the advantages of RTJ flanges?

RTJ flanges provide excellent sealing capability under extreme conditions, such as high pressures and temperatures. They are also resistant to vibration and movement, making them suitable for critical applications in industries like oil and gas.
The seal in an RTJ flange is achieved by compressing a metal ring gasket into the flange groove. When the flanges are bolted together, the ring gasket deforms and fills the imperfections on the flange faces, ensuring a tight and reliable seal.
RTJ flanges are manufactured according to standards such as ASME B16.5, ASME B16.47 Series A and Series B (MSS SP-44), API 6A (for wellhead equipment), and other international standards. These standards specify dimensions, pressure ratings, materials, and testing requirements.
