“GROUND PIPELINE DRONE”TRECOIL SINGLE&MULTI CHANNEL CALIPER PIG

C

L’impresa Costruzioni Impianti Industriali Guatelli S.p.A. svolge attività di manutenzione e costruzione condotte (metanodotti, oleodotti e acquedotti), manutenzione di depositi petroliferi e servizio di pronto intervento 24 ore al giorno per il ripristino della funzionalità degli impianti.Le ultime attività specialistiche inserite nel pacchetto di servizio al Cliente riguardano:- Attività di risoluzione interferenze con altri servizi (linee ferroviarie strade ed urbanizzazioni) dallo studio di fattibilità alla consegna dei lavori comprese le pratiche amministrative di servitù e collaudo.- Attività di Directional Drilling per la posa di condotte con la minimizzazione dell’impatto ambientale.

The GROUND PIPELINE DRONE measures diameter reductions in pipelines such as dents and ovalities. Even diameter variations like girth-welds, wall thickness changings, T-pieces, valves and other installations are detected.

The GROUND PIPELINE DRONE continuously measures the inside diameter of the pipeline through an array of sensing fingers (spider) that are spring loaded to hold them in contact with the pipe wall. A large number of sensing fingers provide optimum coverage of the inside circumference. Wheels at the end of each sensing-finger are in direct contact with the pipe wall.

The spider is separate from the cup to eliminate effects from cup wear. As GROUND PIPELINE DRONE moves through the pipeline, all radial sensor movements are detected and recorded. ID-reductions of 0.4% will be detected.

Odometer wheels generate the distance data which in addition to the measuring data from the spider is continuously collected and stored together with the correlative diameter values.

To locate the GROUND PIPELINE DRONE in the launcher, receiver or during survey, a locator unit is used. The locator unit transmits electromagnetic signals which will be detected by an external inspection tool locator. A pushing flange is used to push the GROUND PIPELINE DRONE into the launcher and to protect the spider against mechanical damage. The data-recorder contains all power, processing and recording circuits in a sealed module within the central body of the GROUND PIPELINE DRONE.

Before the survey the GROUND PIPELINE DRONE is calibrated by using a calibration ring and simulating dents and ovalities with small blocks of specified thickness.

These calibration results are used to draw the calibration curve which forms the basis to determine the diameter reduction which corresponds to the deflection on the chart.

The calibration will be done in 2,5 or 5 mm steps. Each survey chart shows a dent-calibration and a ovality - calibration at its beginning.

During the survey the GROUND PIPELINE DRONE data are gathered in the solid state memory inside the recorder.

After the run a laptop computer is connected to the GROUND PIPELINE DRONE for downloading the data. The interpretation of the complete survey data will be done directly on screen. All interesting details are marked in the chart and a printout is added to the report. Before interpretation begins a minimum acceptable diameter reduction is agreed with the customer.

The interpreter scans the chart for deflections which exceed the agreed value and compiles a features list. All indications exceeding the agreed value and also pipeline features like valves, T-pieces, wall thickness-changes, girthwelds, bends and other installations are listed. The following examples show typical pipeline features:
