Cathodic Protection Inspections and Corrosion Surveys – Analysis & Troubleshooting

Protect Your Infrastructure from Corrosion

Our Houston Engineering Team Provides Corrosion Surveys and Cathodic Protection Inspections

Cathodic protection (CP) surveys and corrosion surveys can improve employee safety and protect the long-term health of your infrastructure. For many companies in the industrial or oil and gas sector, these surveys may be required quarterly in order to stay compliant.

Corrosion can inhibit your equipment from running correctly and cause a significant safety hazard. Dreiym Engineering conducts corrosion surveys and cathodic protection inspections on pipelines, docks, and other structures. We also conduct interference testing and mitigation. 

 The Dreiym Difference

When you contract with Dreiym to conduct your cathodic protection inspections and potential surveys, we take a direct and simple approach. You won’t find a young and overworked representative from a large company, who must report back to his management before any work can be done. You will receive the expertise of a certified NACE cathodic protection specialist and registered professional engineer, on site, the first time, for every CP survey.

This approach allows us to produce solutions more quickly. We also produce detailed solutions and lead any mitigation efforts. Dreiym service companies throughout Texas and the surrounding states.

Below are some of the cathodic protection surveys we can perform. Every survey is conducted by a licensed professional engineer and a cathodic protection specialist.

Our Cathodic Protection Surveys/Corrosion Surveys

  • Annual and regulatory – Follow the required annual and regulatory surveys for your industry.
  • Close Interval Surveys (CIS) – Find out the cathodic protection status for your entire structure.
  • Direct Current Voltage Gradient Survey (DCVG) – Efficiently detect any problems that may impact your pipeline coatings.
  • Alternating Current Voltage Gradient Survey (ACVG) – Evaluate your pipeline coatings by using a signal generator with alternating current.
  • On-Potential Surveys – Evaluate background information and past performance of your system for a broader context.
  • Interrupted Potential Surveys – Gain insight into the current effectiveness of your corrosion protection systems. These tests can be conducted multiple times per year.
  • Cathodic Protection Interference – Multiple tests to detect the presence of interference and provide engineering recommendations.
  • Direct Assessment – An evaluation dig into the pipeline infrastructure to diagnose the causes of a significant issue.
  • Native Potential Survey – Achieve a different acceptance criteria per NACE – 0169 with the results from a native potential survey. This is a survey that’s not practical in many situations.
  • Alternating Current – Current Attenuation (ACCA) – Measure the strength of the electromagnetic field surrounding your pipeline. This can be used to determine the strength of pipe coatings. 
  • Depth of Cover – Evaluate the depth of cover within your system for a better understanding of how long it will take for atmospheric carbon dioxide or chloride ions to reach your pipeline infrastructure.
  • Pipeline locating – Find the existing infrastructure on your property.
  • Pipeline current mapping – Locate pipelines and identify potential issues in your pipeline coatings.
