From design and construction to operations and maintenance, safety is always the highest priority at TransCanada.
Here are some of the industry-leading safety measures we use during construction:
- Only high-strength steel and top quality welding and inspection techniques are used for our pipelines
- Use of corrosion-resistant protective pipeline coating
- Subsoil is carefully screened to remove any rocks or sharp objects that might scratch the epoxy coating on pipes
- Thicker-walled pipes and other safety precautions are taken when the pipeline crosses roads or railway tracks, or is near waterways and communities
- X-rays or an ultrasonic process is used to test welds for even the most minuscule defects
- A record is kept of each weld
- After passing inspection, each weld is coated with epoxy resin
- Completed sections of pipeline are pressure-tested by pressurizing them to a level far greater than they will experience during normal operation. If a leak occurs during testing, we repair or replace the affected section of pipe
