The real-time intellegence delivered by live gas main camera and crawler inspections helps gas distribution utilities and pipeline operators reduce risks, improve efficiency, lower costs and resolve a wide range of operational challenges. Below are some of the ways we help deliver value through our services:

Verify Plastic Tee Installations: ULC performed internal inspection of live 2″ plastic mains to verify if a tee’s cutter was fully protruded into the main to identify faulty installations. Our technicians inspected 286 tees from eight small excavations.

Water Intrusion: Locating water in a gas main and identifying the source of infiltration can be a worrisome task for gas utilities to accomplish. With the water-tight design of the PRX250 Camera Head, our team has helped numerous utilities avoid costly guesswork and quickly resolve water blockages .

Verification of Plastic Pipe Work: Our camera and crawler systems have been used to inspect plastic pipe fusions and coupling installations by looking for gaps and dripping plastic that indicate improper PE pipe work.

Internal Valve Inspection: Our crews utilize our PRX250 Cameras and VGC  Systems to perform highly detailed assessments of valves and verify their location, type and position. In addition, camera operators can ensure the path of the valve is not blocked by debris and ensure proper functionality.

Pre-Insertion Inspection: Visual inspection is used to identify features such as offsets, drip pots, valves and protruding services that might block the PE pipe from reaching its desired location or damage the material while it is being inserted. Issues identified by our crews can be marked for removal or remediation prior to insertion.

Leak Investigation: Live gas main inspection can aid in leak detection by performing a high resolution and detailed inspection of the pipe wall. Evidence of leaks can be found in the form of cracks in the pipe wall, visual evidence of corrosion or areas of active or past water intrusion locations.

Locate Features/Damage Prevention: Prior to trenching alongside the gas main for replacement projects, our crews can identify unmapped features, unknown connections to the main and possible stub services so excavation contractors can safely carry out their work with less risk for third party damages.

Unlocatable PE and Aldyl-A Pipe: ULC Robotics works with gas utilities to visually inspect unlocatable PE and Aldyl-A mains while simultaneously pinpointing the location of the main and its features. This can be recorded my marking out the street surface or by recording highly accurate GPS coordinates in our reporting.
