ESI spring-energized metal C-Ring for internal pressure face sealing applications
Applications:
•Similar to ECI, but higher loads for use with rougher mating surfaces
•Excellent for pressure vessel closures; manways, hand-holes; steam generators, gasoline/diesel engine fire rings, exhaust joints, flanges with a rougher surface finish
•Best choice for non-flat mating surfaces
•For internally pressurized joints
•For externally pressurized joints to avoid passage of working fluid into the seal cavity (reduced working pressure rating)
Features:
•Lowest leak rate
•Internal spring provides high pressure capabilities of 38,000 psi and above depending on application
•All plating options available
•Excellent footprint with good plastic flow of plating material.
•Available in wide range of diameters
•Wide range of eight standard free heights from 1/16" to 1/2"
•Multiple material choices for high temperature strength, good spring-back, corrosion and fatigue resistance
•Uses jacket forces, spring forces and hydrostatic forces additively to increase sealing forces at higher pressures
•Circular, race-track and other custom shapes available
•Tri-lobed or elliptical spring-energized C-Rings available for snap-in/snap-out convenience
