High sealing performance UHV, pressurization, cryogenic, high temperatures, and cyclic conditions! Spring-energized metal seal
HELICOFLEX(R) seal is expected to provide high sealing performance under UHV required for accelerators, high pressure due to pressurization in high-performance engines, cryogenic such as launch vehicles(rockets) fuel systems, high temperatures for fusion energy applications, and even these cyclic conditions (depending on the customer application and leak rate requirements, other our option Delta Seals may be selected.) Our spring-energized C-ring HELICOFLEX(R) seal achieves excellent sealing performance even in severe design conditions through the plastically of the outer jacket combined with the elasticity of the helical spring. [Application Uses] *UHV: Accelerators, SEM, etc. *High pressure: Pressure vessels in nuclear power plants, high-performance engines, etc. *Cryogenic: Launch vehicles(rockets) fuel systems, liquid hydrogen, etc. *High temperature: Fusion energy, etc. *Cyclic conditions [Benefits of Implementation] *Reduction of accident risks *Improved safety *Improved overall performance
