Our Mission

 Objective:
Enbridge Gas Distribution, in collaboration with Braithwaite Drilling Services, used the X-TRX pulling machine to extract outdated and damaged ¾ and 1-inch Schedule 40 steel gas pipes in Etobicoke, Ontario. The objective was to replace the old pipes without disturbing existing utilities and to address issues like past useful life, damage, or leaks.

Key Challenges:

• Trenchless Technology: The goal was to use trenchless technology, avoiding damage to surrounding utilities, which can be difficult when working with older service pipes.
• Utility Coordination: Ensuring no interference with existing sewer services or other utilities that were in place before trenchless methods became common.

Technology Used:

• X-TRX Pulling Machine: This tool does not require cutting, minimizing the risk of damaging surrounding utilities. It also reduces excavation and disruption of the area.

Findings:

• Sewer Service Considerations: Enbridge determined that the installation dates of the existing services meant the sewer service didn't need to be located. Any potential interference with the sewer would have already caused issues, which had not occurred, leading to cost savings.
• Efficiency: The extraction and replacement of each pipe took about 45 minutes from setup to completion, with the pulling rate averaging 6 to 10 feet per minute. During this case study there was 100% success rate for extracting old pipe and installing new.
• Team Efficiency: One gas crew could replace three services per day without rushing or compromising quality, thanks to careful planning (e.g., exposing the service pipe at the gas main a day before removal).

Outcome:

• The use of the X-TRX tool allowed for efficient and cost-effective pipe replacement, minimizing disruptions and safely navigating the complexities of existing underground utilities.
• During the pipe extraction there was no need for entry into the pit as well no mechanical actions occurring within the allowable limit of work to be done at a live gas main
