This section provides correct recommendations and procedures to be followed during the disassembly of pipes and relevant connections.
– Keep all internal and external threads clean.
– Remove the plugs just before connecting the pipes and plug at once all open connections.
– Do not use or reuse semi flanges out of shape more than 0.6 mm in the Centre (see figure).
– Make sure that the seats of O-Rings are undamaged.
– Lubricate all O-Rings.
– Make sure that O-Rings are in place in the relevant seat.
– Tighten regularly so as to avoid distortions or damages to O-Rings.
– Install pipes and support bands letting the latter slightly loosen (tighten the band only after tightening the connections).
