Specifications
316L Octagonal Ring Type Joint (RTJ) Gaskets 
 
Octagonal Ring Joint Gasket:
 
The ring type joint was initially developed for high pressure and temperature
applications found in the petroleum industry and is primarily used in the oil field
on drilling and completion equipments. However, today this product range can
also be found on valves and pipework assemblies, along with some high integrity pressure vessel joints.

Octagonal Ring Joint Gasket Standard
Standard style R ring type joints are manufactured in accordance with both
API 6A and ASME B16.20 size and ratings. Available in both oval and octagonal
configurations, both types are interchangeable on the modern octagonal type grooved flanges.
 
 
A number of ring joint styles are available designed for specific flange types, these are:

Style R
Style R Oval	Style R Octagonal
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 ? Suitable for flat and round bottom groove flanges. Interchangeable on modern octagonal type grooved flanges.	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

 

Style RX

Style BX

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 .
