Product details

API Ring Joint Gaskets are machined from variety types forged solid metal such as Soft Rron,ANSI304,ANSI316,Low carbon and alloy metals(including alloy825,alloy625,Duplex,Monel etc). they are designed for high pressure and temperature applications by selecting the suitable shape and material. Ring joint gaskets assemblies 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 gaskets and grooves are covered in ASME B16.20 and API 6A, API 17D and ASME B16.5/B16.20.

 

Ring joint gasket main including the following kinds:


BKG102A R type Oval Ring Joint Gasket  

Ring joint gasket with oval cross section is initially developed for high temperature and pressure applications.It is still used in the old type round bottom groove today.

 

BKG102B R type Octagonal Ring Joint Gasket  

Ring joint gasket with Octagonal cross section is prefered by morden grooved flanges and has a higher sealing efficiency than oval types.

 

BKG102C RX Ring Joint Gasket 

RX is used at pressures up to 15,000 psi (103 MPa). it is adhered to API 6A and interchangeable with standard Octagonal rings, it can take advantage of container fluid pressure well to effect a seal

 

BKG102D BX Ring Joint Gasket 

All BX gaskets incorporate a pressure balance hole to ensure equalization of pressure which may be trapped in the grooves,it is only used in API 6BX flanges.

BX is used at pressures up to 15,000 psi .

 

Ring joint gasket Specification:

  • 1)To API 6A& ASME B16.20  standard.
  • 2)R Series, RX,BX,IX,AX types are available
  • 3)To fit ASME, BS and DIN flanges.
