Hydrogen, LNG, and nuclear-related equipment demand sealing conditions unlike conventional industries: cryogenic temperatures, high pressure, hydrogen permeation and rapid gas decompression, and radiation exposure. POLY STAR reviews the applicability of Spring-Energized Seals, PEEK components, and special seals based on the actual temperature, pressure, fluid, and installation structure.
We review suitable compounds and seal geometries considering the risk of swelling, blistering, and cracking from high-pressure hydrogen permeation and repeated pressurization/decompression cycles.
General elastomers struggle to retain elasticity and recovery at LNG's roughly -162°C cryogenic temperatures, so PTFE-based spring-energized seals, PCTFE, or metal seals are reviewed based on the installation structure and leakage requirements.
Stable sealing performance under high-pressure operating conditions.
We confirm the availability of materials suited to radiation exposure environments based on the required dose endurance, temperature/pressure, contact fluid, and quality/traceability documentation.
