Specifications

ASME B16.20 SS316L Octagonal Ring Joint Gasket Type R57 12 Inch 900LB

Size: 12" (DN300)

Pressure: 900LB (Class900)

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.

China Gasket Manufacturer Yaang supplies ASME B16.20 SS316L Octagonal Ring Joint Gasket Type R57, 12 Inch, 900LB.

Octagonal-Ring-Type-Joints-RTJ-Gaskets

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 .

Application

Sealing of flange connection in pipelines, valves, pressure containers, 

condensers, heat exchangers, towers, manholes, handholes and so on 

in such industries as petroleum, chemical engineering, metallurgy, electricity, shipping and machinery.
