Metallic Ring Joints

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

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 facng.

A number of ring joint styles are available designed for specific flange types, these are:
