There are tens of thousands of valves spanning TC Energy’s 95,800 oil and natural gas pipeline network across North America. These valves are carefully maintained and inspected to keep our pipelines working safely and smoothly.

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.
