Size/Pressure Class:

½" to 24" " 150 to 2500 ASME B16.20

26" to 36" : 300 to 900 ASME B16.47 Series A

1 ½" to 20" : API 6A

Applications:

• Used for high pressure applications.

Typical Properties:

• High integrity seal at high pressures

• The octagonal cross section has a higher sealing efficiency than the oval and would be the preferred gasket

• Suitable for flat bottom groove flanges

Size/Pressure Class:

1 ½" to 20" : 720 to 5000 API 6A

Applications:

• Used for high pressure applications.

• The Style RX is designed to fit the same groove design as a standard style R making joints interchangeable

• The Style RX has an increased height and utilizes the internal system pressure to energize and improve the seal as internal pressure increase

• Suitable for flat bottom groove flanges

Size/Pressure Class:

1 11/16" to 30" : 2000 to 20000 API 6A

Applications:

• The Style BX energised ring type joint is manufactured in accordance with API 6A for use in high pressures.

• Style BX ring type joints incorporate a pressure passage hole to allow for pressure equalization each side of the sealing faces.

• Style BX is not interchangeable with any other style, and is only suited for API 6BX flanges .
