A Ring Type Joint Flange is a sort of flange that uses a metal ring that sits during a hexagonal groove as a gasket to seal the flange pair. The flanges seal when the bolts are tightened and therefore, the gasket is compressed into the groove making a metal to metal seal. An RTJ flange usually features a raised face with the groove machined into the face of the flange. The raised face doesn’t function how to contain the pressure.
An RTJ flange is a raised face with a ring groove machined into it. This raised face doesn’t function any a part of the sealing means. For RTJ flanges that seal with BX ring gaskets, the raised faces of the connected and tightened flanges may contact one another.
RTJ joints are used for top pressures (Class 600 or over) and/or high temperatures (above 427 °C (882 °F)). They feature machined grooves during which a metallic ring joint is fitted. When the bolts are tightened, the metal joint is compressed between the 2 flanges and is deformed so on create a metal-to-metal contact. But this face doesn’t play any role within the sealing capacity of the unit.

Designs of RTJ flanges
There are two differing types of RTJ flange designs, oval and octagonal cross sections. both types having a identical pitch diameters, octagonal cross sections are more widely used because of higher sealing efficiency with pressures up to 10,000 PSI.
There are other ranges of RTJ flanges that are adapted to deal with both a better pressure (up to 15,000 PSI) and a lower pressure (up to 5,000 PSI). These are called RX and BX styles respectively. The standardized designs of those sometimes includes a pressure passage hole which is made to equalize the pressure on the sealing faces. Sometimes, the internal pressure of flanges and gaskets means no hole is required because the seal pressure balance is maintained internally within the pipeline already.
Benefit of RTJ flanges
The advantage of RTJ flange’s is that the gasket is confined during a groove and has two sealing surfaces. It also tends to be self-actuating,, the sealing pressure, a minimum of on one side, tends to extend with increased service pressure.
Characteristics of RTJ Flanges
The effect of getting used first within the petrochemicals industry means the flanges offer an outstanding metal-to-metal seal under high pressures and high temperatures too. The RTJ flanges typical characteristics include matching groove cuts on the face, and when the bolts are tightened, the gaskets compress into each other providing a strong and robust connection — which is additionally very easy to assemble and disassemble.
Advantages of Ring Type Joint Flanges
Ring Type Joints used for sealing high up to 20,000 psi. RTJ Gaskets are often produced from a spread of material to suit the method application and flange grade. RTJ’s are a particularly reliable and robust sealing.
Disadvantages of Ring Type Joint Flanges
The potential for crack formation at the intersection of the edges and bottom of the groove in RTJ flanges. These cracks can propagate into the bottom metal. They will be prevented by properly contouring the groove intersections, but avoiding the “problem” geometry all at once was preferred.
Ring type joint grooves can also accumulate dirt, moisture, etc when the flange is open, i.e., they’re harder to stay clean. A small amount of injury (including corrosion) on the narrow sealing surface(s) may cause a leak. Also, because the use of RTJ’s declined, warehousing (and finding) the right gasket(s) became a more important concern. Another factor is the grooves and gasket must align properly to assemble the flange and acquire a seal. They need to stay aligned throughout the operating cycle. The latter point becomes a problem when mating flanges is made from different materials, and not providing different hardness materials for flange and ring, and also thermal expansion is a concern. The primary point is a problem at the initial assembly but are often more of a priority at reassembly after service.
In those cases where dissimilar joint materials are in touch and where the piping is 10” nominal size or larger the use of RTJ Flange is strongly not recommended. Thanks to various natures of the 2 materials, ring joint flanges would experience local stresses thanks to differential expansion that potentially could lead on to ring groove cracking. There are known cases of ring type joint flange failures that have led to loss of reactor containment.
