"We do in-line inspections periodically and it gives us an overall health of the pipeline,” John Sadler, Manager of In-line Inspection Canada at TC Energy.

All aspects of the life cycle of a pipeline – from design and construction to operation and retirement – are guided by our comprehensive Operational Management System and strictly overseen by regulatory agencies and government departments. That's why every TC Energy pipeline is rigorously and precisely built with high-quality materials and the latest proven technology, and monitored by expert staff, every step of the way. Take the journey with us, and learn about the life cycle of a pipeline from planning to monitoring and beyond.
