The use of Stop System allows to operate repair and maintenance interventions on pressured piping in service. The intervention area is in fact by-passed, so that there is no poor service and the operators can work in quite safe conditions.
An innovative technology for stopping flows pressured up to 1 Bar. Introbag System works by introducing kevlar ball-plugs into the pipelines without leakages in the air.
- Check of pressures of second stage upstream and downstream the intervention;
- Check of consumption for a correct sizing of by-pass;
- Search with specific equipment of underground pipelines;
- Check of gas-leakages after the execution of the intervention with Metrex equipment;
- Check of manoeuvrability of underground valves;
- Search of derivation points on pipeline buried by asphalting;
- Execution of cleaning and reinstatement of the supply service to usage temporarily interrupted for the intervention executing.
- Inspections management, papers for the authorization for the execution of work, traffic signs;
- Excavation;
- Assistance with crane to the shift of the worked parts;
- Filling up of hollow amounts following the instructions of the commission;
- Road reinstatement.
