Applications
Seals in nuclear power plants require high levels of design competence and quality control, and a willingness by the supplier to respond quickly to immediate needs.
Our nuclear seals typically consist of:
- Molded, fabric reinforced construction (rather than extruded) for close cross section tolerances, no after-cure splice joints, and maximum structural integrity.
- Certified materials that have met the necessary radiation resistance testing.
- All steps in engineering, manufacture, inspection and test are closely controlled by our nuclear quality-assurance program based on ANSI N45.2 and 10CFR50 Appendix B.
Our experts are equipped to handle your needs.
Inflatable Pool Gate Seals for Nuclear Power Plants
Nuclear pool gates are generally supplied with redundant-style fully molded inflatable seals. Fabric reinforcing is incorporated for structural integrity and increased resistance to rupture and tear.
When required, flexible “J” seals can be supplied in lieu of inflatable seals. The gates can be supplied as a hinged or lift-out design.
Airlock Inflatable Seals
Nuclear plants throughout the world use components that we manufacture, including inflatable seals, “O” ring gaskets and custom compression seals for personnel airlock doors. Seal redundancy is built into the design to ensure high sealing reliability.
Fabric Reinforced Valve Seats
Using our unique long press capabilities, we manufacture an 8″ (203 mm) wide, fully molded fabric-reinforced natural rubber expansion joints in continuous lengths, used for large pipe assemblies in power plants. Diameters approaching 8-10 feet (2438 – 3048 mm) are not uncommon. Depending on the requirements, this part can either be molded and spliced endless, or can be step-cured into a complete gasket.
