Description

The sealing design 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. FEATURES & BENEFITS Properties: Pressure energized Cross-section and wall thickness designed to control loading Available for internal, external and axial pressure Range of materials (Alloy X750, 718, Waspaloy and other exotic metals) Platings and coatings: silver, gold, PTFE (others available) Leak range: Approximately ≤ 25 cc/min @ 50 psig Nitrogen per inch of diameter to ≤ 1 x 10-4 std.cc/sec Air. The actual leak rate will depend on seal load, surface finish, and surface treatment. Optional Features: Tribological wear-resistant coatings available Custom shapes and sizes available PRODUCT APPLICATIONS Oil & gas: downhole drilling/MWD Industrial turbines: fuel systems/nozzles Valves: body/bonnet, back seat sealing Aerospace/space: turbopump, fuel systems, nozzles/injectors, cryogenics Automotive: turbochargers, exhaust
