Reconstruction of a gaz pipeline, Senneville/Sainte-Anne-de-Bellevue

Reconstruction of a gaz pipeline, Senneville/Sainte-Anne-de-Bellevue

  • Construction Management

Gaz Métro had planned maintenance and renovation works on a section of its distribution network, located in the municipalities of Sainte-Anne-de-Bellevue and Senneville. This gas pipeline had been built in 1957, with state of the art technique for the time, and was still considered in an acceptable condition. However, Gaz Métro had to replace the gas pipeline coating, no longer in a condition good enough to protect the underneath steel against corrosion.

The project included the rebuilding, on approximately four kilometers, of a main natural gas pipeline: first, the removal of the actual coal tar coating, a material no longer used as it tends to dry and become fragile, and then, the installation of a new coating. This project was in two parts:

  • The 3,845 m gas pipeline between the transfer station and Chemin Sainte-Marie Road in Sainte-Anne-de-Bellevue;
  • The underground gas pipelines at the transfer station itself.
