As required
Depending on the type of Metal Seal, the solution can be used for static and semi-dynamic face or axial sealing in extreme temperature, pressure, vacuum, and radiation environments.
Applications include:
- Low to moderate load with high spring back (C-Seal, V-Seal, E-Seal)
- Medium to high load with increased spring back and wider sealing surface (Spring-Energized C-Seal)
- Ultra-high vacuum and cryogenic sealing (Aluminium Spring-Energized Seal, O-Ring)
- Shaft and bore sealing in semi-dynamic, rotary, and reciprocating applications (Axial C-Seal, Lip Seal, Comma Seal)
- Non-circular and shaped geometries (Shaped Seal, Machined Seal)
- High spring back for large flange movement or thermal cycling (V-Seal, E-Seal)
- High seating stress for rough surface finishes or soft flange materials (Spring-Energized C-Seal, Aluminium Spring-Energized Seal)
- Long-term static sealing under radiation exposure (C-Seal, Spring-Energized C-Seal)
- Standard fitting interfaces (Boss Seal for AS5202, E-Seal for AS1895)

天然ガスによる発電用ガスタービン
A natural gas turbine is a type of internal combustion (IC) engine, converting the heat produced by natural gases into mechanical energy. This energy is then supplied to power generators that produce electricity for residential and industrial use. Gas turbines are used to power aircraft, trains, ships, electrical generators, pumps, gas compressors, and tanks. There are three significant manufacturers: General Electric of the US, Siemens of Germany and Mitsubishi Hitachi Power Systems of Japan.
