MIRAGE – servis & monitoring Ltd. company is active on the slovakian and czech market in the field of anti-corrosion protection of buried oil, gas and water (metal) lines since 1998. Our workers are certified in accordance with european norms (EN) and comply to highest required standards in the oil, gas and water anti-corrosion protection applications.
We have experienced diagnostics and projection specialists complying to the european norm (EN) 15257, Levels 1,2,3. Our reach knowledges and practical experiences with protection of oil, gas and water (metal) lines against false DC (direct current) currents as well as AC (alternate current) corrosion influences (induced currents from high voltage power networks and stations on oil, gas and water lines) make us a perfect partner for any oil, gas and water utility company facing corrosion problems on their buried lines.
In carrying out a survey, the surveyor walks the pipeline route testing at regular intervals with the probes in a position of one in front of the other, separated by one to two metres, parallel and preferably above the pipeline, (though not essential provided you can pick up the voltage gradient from faults in the pipeline route). As a fault is approached, the surveyor will see the milli-volt meter start to respond to the ON/OFF pulsed current, which is either a coating fault or interference from another structure. When the fault is passed, the needle deflection completely reverses and slowly decreases as the surveyor moves away from the fault. By retracing, the position of the probes can be found where the needle shows no deflection, ie: a null. The fault (defect) is then sited midway between the two copper/copper sulphate half cells.
More than 3000 km of inspected lines brought us on the top of anti-corrosion protection service providers in Slovakia and Czech republic.
