Briefing

Ring joint gasket, a high-pressure gasket is largely used in offshore petrochemical and natural gas industry applications

Detailed

Ring Joint Gasket are heavy duty, high-pressure gaskets largely used in offshore petrochemical and natural gas industry 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 - API Std 6A BS EN 12560-5
 
Materials:
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.
The principa types of material are:
