Gasket designed for cryogenic sealing of liquified gasses
Gaskets in cryogenic applications face extremely challenging conditions as the environment is very cold, materials become brittle, expansion / contraction rates of the joint differ and cryogenic gasses are atomically small and therefore difficult to seal. Our line of Revoseal semi-metallic croygenic gaskets are designed to have lowest leak rate possible even for the most challenging liquified gasses.
Gaskets for Cryogenic Liquified Gasses
- Liquid Argon Gaskets (Ar)
- Liquid Carbon Dioxide Gaskets (CO2)
- Liquid Hydrogen Gaskets (H)
- Liquid Helium Gaskets (He)
- Liquid NitrogenGaskets (N)
- Liquid Oxygen Gaskets(O)
- Liquified Natural Gas Gaskets(LNG)
Gasket Challenges of Cryogenic Temperatures
- Low ductility (plastic deformability before fracture)
- Increased embrittlement of the material
- Thermal shrinkage
Specialty Material Gaskets
All of the Revoseal gaskets can operate at cryogenic temperatures and are constructed from a stainless steel with a PTFE or graphite soft seal design. Specialty alloys like nickel alloys can be utilized in our JG / JP gaskets for improved ductility.
When thermal expansion or contraction is a problem as a process thermally cycles, the Revolution gasket is ideal as it acts like spring and dynamically responds to expanding or contracting joints.
All the Revoseal cryogenic gaskets require a very low sealing force when compared to graphite or spiral wound gaskets and will not over-compress like PTFE or graphite, due to the metal-to-metal seal in combination with a PTFE / graphite soft seal. This metalic seal protect the PTFE & graphite from being over-compressed and becoming brittle.
