Hello Every one,
could you please give me information about the ring joints gaskets:
- why and when is suggested their utilization;
- which are the referential standards;
- general theory about their construction, different styles ...;
- applications.
Thanks in advance

RE: Ring Joint Gaskets
Ring Joint Gaskets are produced from different solid metal types. They are used to stand high pressure and temperatures and they are employed where corrosive agents are present. These gaskets are obtained by mechanical working from forged or laminated metals in one single piece.
Ring Joint Gaskets are strictly manufactured to API-6A/ASME B16.2 specifications.
Ring Joint Gaskets shall be either octagonal or oval in cross section and identify by R, RX or BX number that relates to flange size (NPS), pressure class and appropriate flange standards.

Our extensive vaporized oil heating system is all RTJ flanges even though it is only 70# @ 700F.
RE: Ring Joint Gaskets
Which are the differences with the RX style ?
Thanks
RE: Ring Joint Gaskets
As a side note, the R type rings are metal seals directly on the flanks of the donut. BX type glands completely enclose the ring and butt up to the raised face of the flange. The difference is in make-up forces creating the seal due to stud/nut torsion at the flange.
R type glands are typical of the valve industry, BX is more wellhead application.
