RING TYPE JOINTS

Kent & Yorkshire Gaskets supply only API monogram approved Ring Type Joints. For use in the oil, gas and petrochemical industries. Used for applications subject to high temperature and pressures. Manufactured in full compliance with International standards.

 

The carefully controlled hardness of the Ring Type Joint guarantees a very good seal without damaging the surface of the flanges. Available in 3 styles - Style R , Style RX & Style BX, and in a variety of materials. (Further information given below). In accordance with ASME B 16.20 and API 6A.

Style R Oval and Octagonal configurations are interchangeable on flat bottomed groove flanges. Oval section being a modified version providing better sealing performance.

 

Oval - The contact face is in oval shape. It provides a high reliabililty seal. Fits the round and flat bottom ring groove flange. These gaskets are manufactured in accordance to API 6A of ASME B16.20 to suit API613 and ASME/ANSI B16.5 Flanges. 

 

Octagonal - Dimensionally more accurate and with a better surface finish than the oval style because it consists of straight surfaces only. Fits only the modern flat bottom groove flange. A higher torque load is required to flow the gasket material into imperfections of the flange facings. These gaskets comply with API6A of ASME B-16.20. to suit API 6B and ASME/ANSI B16.5 Flanges

Style BX - used for very high pressures up to 20,000 psi. A pressure balance hole equalises any pressure which may be trapped in the grooves.

 

Typical high pressure and temperature applications where these gaskets are used include valve and pipe-work assemblies in oil field drilling and refining applications.  

 

When correctly fitted, the style BX gasket allows virtual face to face contact of the flange faces.

 

 

The RX type RTJ gasket is manufactured in accordance to API 6A and ASME B16.20 to suit API 6B and ASME/ANSI B16.5 flanges. The RX is a pressure energized version of the R octagonal gasket and fits the R type flat bottomed groove. The RX has an increased height and utilizes the internal system pressure to energize and improve the seal as internal pressure increases. Some RX sizes have a pressure relief hole to equalize pressure on both sides of the sealing faces.

 

The ‘RX’ style Octagonal RTJ is interchangeable with style ‘R’ Oval and Octagonal RTJ’s with the same ring size designation number and can be inserted into standard flanges with flat bottomed ring grooves. As the ‘RX’ style RTJ’s are much taller than standard style ‘R’ RTJ’s, the stand-off distance between the mating flanges will be greater
