Metallic Ring Joint Gaskets

Metallic ring joint gaskets are heavy duty, high-pressure gaskets largely used in offshore petrochemical applications. These ring type joints are precision-engineered components designed to be used in conjunction with precision-machined flanges. All our ring type 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.
