Pipeline Integrity

Learn more about pipeline integrity through these short videos.

Pipeline Pigs

Our member companies deploy sophisticated “in-line” inspection tools (pigs) that inspect pipelines from the inside to identify changes such as dents or wall thinning that could threaten the integrity of the pipeline. In this video we are shown how a pig is launched. Courtesy of Rosen Inspection

Pipeline Coating Defects

The pipeline industry has been using increasingly more sophisticated tools to detect potential damages to pipelines. This video shows how such tool using a sensor is able to detect a crack in the pipeline. Courtesy of Rosen Inspection

Pipeline Integrity

The operations of a pipeline is a complex system that involves numerous steps and use of technology. In this video, we are shown a pipeline inspection tool traveling through a pipeline, the information it collects and how this information is fed and analyzed by a computer program that will allow a pipeline operator to “diagnose” the integrity of its pipeline.

Pipeline integrity means that the pipeline and all its related components are running properly.

When pipelines are not operating properly, it poses a risk to public safety as well as pipeline company employees and other workers. Because pipeline safety is the top priority of CEPA member companies, pipeline integrity is critical to the pipeline business.

Pipelines move large quantities of natural gas, crude oil and petroleum products. And as with any physical infrastructure, pipelines can develop leaks or even rupture — these qualify as failures in pipeline integrity and are of grave concern to CEPA member companies. Loss of pipeline integrity can result in leaks of crude oil or natural gas, which can negatively impact the public and the natural environment.

Ensuring pipeline integrity is the core business of CEPA member companies. Pipeline integrity is maintained through proper design and construction, monitoring and inspections and maintenance protocols.

Design and construction

  • Ensuring pipeline integrity starts with proper pipeline design and construction with safeguards and protective equipment.
  • Routes are chosen to minimize potential impacts and above-ground warning signs clearly mark pipeline rights of way to avoid human interaction with the pipeline
  • Pipelines are coated with specially designed materials to protect against corrosion and environmental damage.


  • Our members monitor their pipelines twenty four hours a day, seven days a week from remote control centres across the country.
  • These control centres are equipped with computerized sensing and control systems, including automatic leak detection alarms and shut-off devices in case of emergency.
  • Control centre personnel undergo rigorous emergency training procedures, and are always ready to respond to any potential incident.

Inspections and Maintenance

  • Every day workers are on the ground, inspecting equipment and making sure everything is functioning as it should.
  • Maintenance and inspection staff repair pipelines, pumps, valves, and other equipment and are continuously checking against safety requirements and calibrating instruments.

Safety & the environment

“The safety and environmental practices we employ are among the most rigorous in the world and we continue to advance key technologies to get even better.” — Brenda Kenny CEPA President & CEO
