External Pipeline Integrity Assessments
Oil & Gas Pipelines and Facility Piping
Integrity Assessment - Providing visibility, maximizing efficiencies and ensuring integrity
As pipelines age, the threat to integrity rises and without a high level of understanding of the pipeline’s condition, the risk of failure is high. Corrosion Service recognizes that this level of risk is intolerable and provides a suite of services designed to ensure that the exact condition of the pipeline is known. With decades of External Corrosion Direct Assessment (ECDA), Close Interval Potential Survey (CIPS), Direct Current Voltage Gradient (DCVG), AC Current Attenuation (ACCA), Alternating Current Voltage Gradient (ACVG) and External Corrosion Engineering Assessment (ECEA) experience backed with a comprehensive research and development program Corrosion service can provide a level of confidence not available in the market.
Our External Corrosion Engineering Assessment (ECEA) service was born out of the (ECDA) program with the need to analyze higher risk pipelines and station facilities. Using conventional survey techniques, its risk-based approach provides a level of visibility not previously available to pipeline operators and allows them to allocate rehabilitation resources in a cost effective and targeted manner.
Our team and services that we offer
All pipeline systems are different, and whether the line is new build, 10 or 50 years old, our talented team of industry professionals is empowered to understand the unique characteristics of every enquiry. This is important because as an organization, Corrosion Service strives to provide the extremely high level of support and partnership to provide the customized solutions that our clients require on a daily basis.
Branch offices are strategically located throughout North America and are the primary line of contact for Integrity Assessment clients. Each branch office is designed to provide front line engineering expertise, project management support and field services in collaboration with our engineering hubs that provides high-level analysis and reporting services. Team members are highly trained, with all engineering staff certified at various levels by the National Association of Corrosion Engineers International.
Our survey services are not like others. We routinely compensate our data, based on decades of research, for more accurate defect identification. This avoids missing or mischaracterizing anomalies that could cause a threat to pipeline integrity.
Our data analysis can account for:
- Spatial Alignment
- DC/AC Interference
- Pipeline Depth
- Telluric Effects
- Dynamic Stray Currents from Transit Systems
- Post survey analysis, to avoiding operator error
- Stray Current Fluctuations
Our Integrity Assessment field services include:
- Alternating Current Voltage Gradient (ACVG) Surveys
- AC Current Attenuation (ACCA) Surveys
- Close Interval Potential (CIS/CIPS) Surveys
- Direct Current Voltage Gradient (DCVG) Surveys
- External Corrosion Direct Assessment (ECDA)
- Prioritization of In-Line Inspection (ILI) results using ECDA methodology
- External Corrosion Engineering Assessment (ECEA) Surveys
- Stress Corrosion Cracking (SCC) Surveys
- Surveys within Stations using ECDA methodology

The Corrosion Service Technical Library that Documents our Past and Defines our Future
Corrosion Service has and remains a leader in the corrosion control industry, supporting the various industries in North America and around the World, ensuring asset integrity by providing responsible engineering services. As part of our continued commitment we would like to welcome you to our electronic Library as the place to view our External Corrosion Direct Assessment (ECDA), Close Interval Potential Survey (CIPS), Direct Current Voltage Gradien (DCVG) and External Corrosion Engineering Assessment (ECEA) technical papers written and presented over the past 69+ years that have supported the corrosion industry advancement.
We also converted a prime corner office into a Library at our Head Office and dedicated the room to Sorin Segall because of his commitment to Corrosion Service, the numerous papers presented, the engineering mentoring within Corrosion Service and to our industry. We would be pleased for you to come and view this comprehensive library that includes various text books, relevant publications, all NACE Materials Performance magazines presented since first publication, technical bulletins and various other related corrosion related print material.
Since our founding in 1950, we have built an extensive portfolio of specialist products for the corrosion prevention industry.
Our materials supply team has access to a full-range of Cathodic Protection materials both manufactured in-house and sourced from partner suppliers. Our dedicated supply chain team is based in Toronto alongside our material distribution hub, which is capable of delivering materials throughout the world on short notice.
