KLINGER RING TYPE JOINT TYPE R OVAL

Information:

Ring Type Joint are designed to be used in high pressure applications and can be manufactured from a number of materials to suit the process media and the flange materials.

Ring Type Joint are precision machined metallic rings which are designed to be used with API 6B, ASME B16.5 and API 6BX (dependent on the gasket style) flanges. RTJs are often used in offshore applications and certain styles can be adapted for subsea installation.

Klinger hold a large range of RTJs in stock in a number of profiles and materials.

Can be used for high pressures.
Wide range of materials available.

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 or a Maxiflex CR-RJ, 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.
