Tutte le valvole con prolunga fino

Tutte le valvole con prolunga fino al DN 80 devono essere sottoposte al collaudo funzionale e di tenuta, atto a verificare il corretto posizionamento

Hasil (Inggris) 1:

All valves with extension up to DN 80 must be subjected to functional testing and sealing, to check the correct position The signature and the date of the Inspector of Negri Fratelli mounting cycle indicate that it was consented to the test, that thethe same had a favourable outcome and that it meets the requirements of this procedure.Must use appropriate measuring instruments (pressure gauges) and calibrated. The calibration should be done by means of pressure gauge

Hasil (Inggris) 2:

All valves with extension up to DN 80 are to be subjected to functional testing and sealing, designed to verify the correct positioning
The signature and the date of the inspector of the Negri brothers on the assembly cycle show that was given consent to the test, that the
same has had a favorable outcome and that it meets the requirements of this procedure. They must use appropriate measuring instruments (gauges) and calibrated. Calibration should be performed on the pressure gauge
