Product details


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.
