Ring Joint Gaskets for Pipe  are machined from variety types forged solid metal like soft iron,SS316,
,Low carbon and alloy metals such as Nickel base alloys, Cobalt base alloys (Stellite), super duplx SS etc,
and we are competitive in alloy metals materials.
Ring Joint Gaskets  are designed for high pressure and temperature applications by selecting suitable shape and material. Ring joint gaskets assemblie seal by an initial line contact or an
edging action as the compressive forces are applied. The hardness of the ring should always be 20-30HB 
less than the flanges hardness to prevent flange deformation. Dimensions for standard ring joint gasket
and grooves are covered in ASME B16.20 and API 6A, API 17D and ASME B16.5/B16.20.
Metal Ring joint gasket main including the following kinds:
R type Oval Ring Joint Gakset
Ring joint gasket with oval cross section was initially developed for high temperature and pressure application
and still used in the old type round bottom groove today.
 R type Octagonal Ring Joint Gakset
Ring joint gasket with Octagonal cross section is prefered by morden grooved flanges and has a higher sealing
efficiency than oval types.

Both R ring type joints are designed to seal pressure up to 6,250 psi in accordance with ASME B16.5 pressure
ratings and up to 5,000 psi in accordance with API 6A pressure ratings.
RX Ring Joint Gakset 
RX is used at pressures up to 15,000 psi (103 MPa). it is made to API 6A and interchangeable with standard
Octagonal rings, it can take advantage of container fluid pressure well to effect a seal.
BX Ring Joint Gakset 
All BX gaskets incorporate a pressure balance hole to ensure equalization of pressure which may be trapped in
the grooves,it is only be used in API 6BX flanges. BX is used at pressures up to 15,000 psi.
IX and AX special types are also available in special applications.
