Operations on the system
B.3.7 Repair interventions on fittings and pipes
If gas leaks occur from the pipe or fittings, replace the pipe assembly. The pipe is not provided with the fittings and these must
be obtained separately.
•
Remove the pipe to be replaced together with its end fittings.
•
Check the condition of the new pipe that is pre-formed into the same configuration as the pipe to be replaced and fit new fittings
and o-rings at its ends.
•
Fit the pipe by fitting its ends into the seats of the components to be connected and ensure that they are fitted fully home.
•
Check the pipe end centre line is aligned with the centre line of the fitting to which it is to be connected to prevent pretensioning.
•
Pre-tighten the fitting nuts by and then tighten to the specified torque. For EMER fittings, follow the procedure described in the
relevant chapter.
•
Apply the fastening brackets checking that the tube is not subjected to excessive tension.
•
Restore system operation by carrying out a hydraulic seal test following the procedure described in the warnings at the beginning
of the chapter.
