Direct Current Voltage Gradient Surveys
Protect the Integrity of Your Pipelines
When the protective coating over a pipeline is scratched and the metal starts to corrode, it can damage the whole system – and be detrimental to both the business and the environment. Direct current voltage gradient (DCVG) surveys from Dreiym Engineering are an effective way to identify corrosion within your system, so that it can be addressed.
Your pipelines need a protective coating to keep safe from corrosion over time. A DCVG survey from Dreiym can help identify problem areas.
DCVG Surveys are Ideal for:
- Oil and gas companies
- Pipeline constructors
Pipelines are regulated by the Pipeline and Hazardous Materials Safety Administration, a division of the US Department of Transportation. DCVG surveys are an important step in advancing the safe transportation of oil, energy, and other potentially hazardous materials.
Detection of Pipeline Coating Holidays
When the epoxy wears from your pipe, there is a holiday. There is no protection, and corrosion becomes a likelier occurrence. Holidays can form through normal wear and tear. They can also form in the process of moving pipes into place. The DCVG survey checks the condition of the pipe so that you can remain aware of any potential vulnerabilities.
A standard three-man crew typically covers between 1.5 and 3 miles of pipeline per day, depending on the condition of your fields. When our team of cathodic engineers identifies a holiday, we tag it with a high accuracy GPS meter, and put a stake in the ground.
