Rtj flange

What is a RTJ gasket for? RTJ flanges dimensions are covered in ASME B16. Pipe Flanges and Flanged Fittings for size NPS ½” to 24” for above NPS 26” to 60” it should be as per ASME B16.

During dimensional inspection of flange, you should check for. A metal ring is compressed into a hexagonal groove on the face of the flange to make the seal. A Ring-type Joint ( RTJ ) can also have a raised gasket face with the difference being the ring groove machined in this face.

This groove will accommodate a steel ring gasket for flange mating. The Flat Face, FF, flange has a gasket surface that is in the same plane as the bolting circle face. The flanges seal when the bolts are tightened and the gasket is compressed into the groove making a metal to metal seal.

This raised face does not serve as any part of the sealing means. The groove assures that the ring centers itself when the bolts are tightened. A ring joint flange features a circular groove to accommodate a ring joint gasket (oval, or rectangular). Well the difference is that in RTJ type the Ring (Sometimes referred as gasket) and the flanges are THREE DIFFERENT PARTS.

Flange (Groove) From the above list, we have Three Separate parts.

The ring type joint gaskets are either octagonal or oval in cross-section. RTJ gaskets are generally used for high pressure and high-temperature applications. It is widely used in refinery, petrochemical and oil field drilling industries.

Table with dimensions of Stud Bolts used with Raised Face and Ring Type Joint Flange connections, Pressure Class 15 ASME B16. Stud Bolts Dimensions for Raised Face and Ring Type Joint Flanges - ASME B16. Diameter of Hub at Weld H. Ring Joint Gaskets are used with Ring Type Joint ( RTJ ) flanges. A high surface stress is developed between an RTJ gasket and the flange groove when RTJ gasket is bolted to a flange.

This leads to plastic deformation of this gasket. Thus, the hardness of the gasket is kept less than the hardness of the flange groove. A ring type joint flange may have a raised face with a ring groove machined into it.

RF or RTJ ), and rating, for effective joint connections. Manufacturer of Rtj - Class 6Flanges As Per ANSI B 16. A One Engineers, Mumbai, Maharashtra. Length dimensional tolerances for all Stud Bolts: length to inch tolerance = ± 1. The length of the Stud Bolt does not include the height of the chamfers (points).

Texas Flange has served the petrochemical, process, and waterworks industries for over decades.
