Specifications

2-according to ASME B16.20 and API 6A

RTJ Ring Type Joints

Metallic ring type joint gaskets are heavy duty, high-pressure gaskets largely used in offshore and onshore petrochemical applications. They are precision-engineered components designed to be used in conjunction with precision-machined flanges. All our Ring Joints are manufactured according to ASME B16.20 and API 6A.

 

The gasket material is selected on a number of grounds primarily; chemical compatibility with the media and the hardness of the flange. The gasket material ideally needs to be roughly 30 Brinell less than the flange material to ensure sufficient deformation of the gasket without damaging the flange facing.

 

Worn, pitted or corroded flange sealing surfaces can impede the sealing ability of RTJ gaskets. In such instances, a serrated octagonal RTJ gasket, covered with flexible graphite, can provide a temporary or emergency solution until the flange can be repaired or replaced.

 

The sealing surfaces on the ring joint grooves must be smoothly finished to 63 Microinches and be free of objectionable ridges, tool or chatter marks.

 

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 .
