- Design phase
- Prototype manufacturing and testing
Life Cycle Testing for four load cases in the presence of the customer. Tests have been carried out under temperature and 1 bar g overpressure between the plies.
– Two different helium leak tests after the cycle test in the presence of the customer
– After having successfully passed all tightness tests the expansion joint has been sent to a laboratory to carry out sections of the welding seams (Metallographic examination) - Series production
Design code: EJMA
Temperature: -10 °C to +240 °C
Design pressure: -1 bar g to 1 bar g
Test pressure: 2.1 bar g
UHV application: Feedthroughs for In-Vessel Coils: Ultra high vacuum (UHV) Upper Ports Feedthroughs and the Lower Ports Feedthroughs are used to facilitate the transfer of electrical power and cooling water across the separation boundary.
