This morning we have carried out the leak test of the recently added SDB1-SQB1 minilink.
A large leak ( >E-4 mbar.l/s ) is present in one of the parts of the SDB1-DQB1 minilink = the top access flange DN200. The defect is likely due to a misplaced gasket.
Other joints have been found to be leak-tight (LR<1E-8 mbar.l/s)
- SQB1 viewport joint
- DN250CF flanges, DN100CF flanges, special metal sealed flange
- Tower bottom flange
*** We started venting the DET tower in order to perform the repair intevention as soon as possible, planned for the late evening (11PM to 1AM) ***
