Metal C-Rings
Sealing Concept
The sealing concept of C-FLEX™ metal C-rings is based on the elastic deformation of a metal “C” substrate which, during the compression cycle, gives a contact point on each sealing surface.
The substrate characteristics determine the compressive load of the seal. This load combined with an accurate compression rate results in a specific pressure which is directly related to the sealing level obtained. A certain specific pressure is necessary to make the seal flow into the flange imperfections. In service, the system pressure supplements this load. A softer surface treatment is available to increase the plasticity of the seal and reduce the specific pressure necessary to reach the desired sealing level.
INQUIRIES
C-FLEX™ Types
The opening of the C-FLEX™ seal is typically oriented toward the system pressure. In service, the system pressure “energizes” the seal providing supplemental load. This energizing effect increases in direct proportion to increases in differential system pressure. Below are typical seal orientations:
-
Internal Pressure
-
External Pressure
-
Axial Pressure
