The style Flexpro™ faced Ring Type Joints are suitable for use in high pressure applications where API or ASME ring groove style flanges are to be sealed.
The Ring Type Joint metallurgy is generally specified by the customer to match the flange material and to be suitable for the application media. The relevant 23° angled sealing faces of the Ring Type Joint are machined with concentric serrations to provide a low stress sealing face to which a soft sealing material is applied. This low stress sealing capability avoids the need to deform the metal of the Ring Type Joint. Standard Ring Type Joints can only be used once, however, after careful removal of the used soft facing material and inspection confirming the integrity and quality of the metal Ring Type Joint, the facing material is replaced and the Flexpro™ faced Ring Type Joint re-used.
