The new method is designed to detect pitting corrosion of a pipeline wall by ultrasonic transducers used in ultrasonic thickness measurement.
The upgraded instrument has new MFL and TFI measuring systems equipped with new-generation five-component sensors.
Both upgraded tools passed acceptance testing at the test ground, as well as at sections of the existing oil pipelines.
36" tool has expanded the range of combined magnetic inspection tools with speed control that can be operated in explosive areas.
The inspection was carried out using in-line tools developed and manufactured by Transneft Diascan: multichannel geometry tools, magnetic inspection tools employing the MFL and TFI technologies, as well as combined ultrasonic (WM + CD) tools.
The diagnostics were performed as part of Transneft’s annual integrated programme of diagnostic examination of pipelines and PS (oil pumping stations) facilities for 2017.
According to the diagnostics’ results, the condition of the examined facilities was declared satisfactory. The defects detected in the inspection process will be eliminated during scheduled repairs.
Volunteers of Transneft Diascan have conducted the Tree of Wishes voluntary campaign for boarders of the Lukhovitsy social rehabilitation centre for minors (Lukhovitsy, Moscow Region).
It is intended for in-line inspection of pipelines with diametres of 1020/1067/1220 mm (40/42/48") and allows to detect slit-shaped defects at early stages, which improves oil and petroleum products pipelines safe operation.
The new power supply system of inspection tools reduces the cost of conducting in-line inspections and increases the reliability of operation of in-line devices.
