Accurate diagnostics - reliable protection: our company has mastered the DCVG method of inspection of insulation coating.
Our company has expanded the range of services in the field of diagnostics of underground structures (pipelines), successfully mastering and introducing into production practice the DCVG method (Direct Current Voltage Gradient - DC voltage gradient method). This is a modern technology for contactless inspection of the insulating coating of underground pipelines, which allows you to identify defects with high accuracy without opening the ground.
What is the essence of the method? A direct current signal is supplied to the pipeline, and an operator with highly sensitive electrodes moves along the route, recording changes in the voltage gradient on the ground surface. Current leakage points indicate insulation damage.
Key advantages of DCVG:
· High accuracy - the position of the defect is determined with an error of up to ± 15 cm, which dramatically reduces the amount of pitting and repair costs.
· Quantitative assessment - the method allows you to calculate the degree of severity of the defect (% IR) and divide them into requiring immediate elimination and insignificant.
· Determination of corrosivity - analysis of current direction makes it possible to understand whether the defect is an anode zone, that is, a place of active corrosion.
· Work without stopping pumping - inspection is performed on the existing pipeline, without disturbing the transportation mode.
· Compatibility with other methods - DCVG results are well complemented by cathodic measurements and ILI data.
The specialists of our company have already applied this method at a critical facility - the main oil pipeline of a large international consortium. During the work, sections of the route were inspected and the high efficiency of DCVG technology was confirmed.
We express our sincere gratitude to the Client's management for the trust and the opportunity to test the method at the oil export pipeline facilities. The experience gained was an important step in the development of our competencies and confirmed the readiness of the team to solve problems of any scale.
