Štandardne riešime opravy chýb aj s únikom média pod tlakom za prevádzky:
- pipeline corrosion defect repair,
- welding joint defect repair,
- cracks repair,
- pipeline wall lamination repair,
- third-party damage and other manufacturing and construction defects.
We use a number of methods to repair these defects under pressure without shutdown. The choice of which repair method we use depends mainly on the operating parameters (pipeline diameter, chemical composition of the product in the pipeline and its possible chemical effects, temperature and pressure), type and size of the damage, and space available at the repair site, for example:
- zvárané delené oceľové objímky vyplnené kompozitnou výplňou (tlakové a beztlakové),
- kompozitná bandáž pre opravy dlhých a členitých úsekov potrubia,
- výrez a výmena poškodenej časti za prevádzky,
- any minor repair of scratches, welds and similar minor defects which can be fixed technologically by welding, are repaired using an approved WPQR welding procedures in accordance with the ASME PCC-2 (Repair of Pressure Equipment and Piping) standard.
If any leak occurs at the defect's site, we use leak repair methods.
