RTJ Flange

1.what is RTJ Flange？

A Ring Type Joint Flange, abbreviated as RTJF, is a type of flange that uses a metal ring that sits in a hexagonal groove as a gasket to seal the flange pair. The flanges seal when the bolts are tightened and the gasket is compressed into the groove making a metal to metal seal. An RTJ flange usually has a raised face with the groove machined into the face of the flange. The raised face doesn't serve as a way to contain the pressure.

Ring Type Joint Flanges are used for high-pressure applications up to pressures as high as 15,000 psi (103 MPa). It is only furnished only on steel or alloy valve bodies and usually needs to specify when ordering. The flanges usually come in blind, slip-on, threaded, and weld neck.

The most common RTJ gasket is the R style with an octagonal section, as it ensures a very strong seal (the oval section is an older type). A “flat groove” design, however, accepts both RTJ gaskets having an octagonal or oval section.

The benefits of using an RTJ flange and ring is that the gasket is confined to a groove and has two sealing surfaces. The groove assures that the ring centers itself when the bolts are tightened. It also is self-actuating meaning that the sealing pressure increases when the process pressure increases.

The ring joint flanges (RTJ) is used when a metal-to-metal seal between the mating flanges is required (which is a condition for high-pressure and high-temperature applications, i.e. above 700/800 C°). A ring joint flange features a circular groove to accommodate a ring joint gasket (oval, or rectangular).

RTJ flanges dimensions are covered in ASME B16.5 – which covers Pipe Flanges and Flanged Fittings for size NPS ½” to 24”. Class 150, class 300, class 600... .
