Material and spring design considerations for spring-energized sealing systems.
Metal energizers preload polymer sealing lips under motion, corrosion, thermal variation and limited assembly space.
Phynox (UNS R30003) combines strong corrosion and fatigue resistance with high elasticity. Cold rolling and subsequent aging enable higher strength for spring-energized seals. We supply precision slit strip for cantilever, V-type and helical seal energizers.
International seal manufacturers identify UNS R30003 cobalt-based alloys as spring-material options for energized seals in demanding service.
OmniSeal spring-energized seals use metallic springs to maintain sealing loads. Its subsea sealing technical literature lists UNS R30003 as a spring-material option for corrosion-resistant valve and manifold sealing applications.
Turcon Variseal supports several energizer geometries. Its published spring-material guide identifies UNS R30003 as an available option (material code E) for demanding service including crude oil and sour media.
We provide R30003 precision slit strip with controlled widths, edge quality, burr limits and suitable coil packaging.
For R30003 strip below 1.00 mm thickness and slit widths below 125 mm, standard width tolerance is +0.20/−0.00 mm; a precision option of ±0.10 mm is available. Narrow slitting, slit-edge quality and burr control are supported; other dimensions follow the agreed order specification.
Precision slitting with tight width-tolerance and edge/burr control; final width tolerances are specified for thickness and slit width.
Delivery specifications cover temper, dimensional tolerance, slit-edge quality and strip surface condition. Thickness-width combinations follow the applicable product specifications.
