LIVE GAS MAIN I N S P E C T I O N S E R V I C E S

From the build-up of calcification to debris and water intrusion, our crews quickly identify the cause of poor pressure in gas distributions mains to resolve issues quickly.

Our crews identify unmapped features and possible stub services so excavation crews can avoid third party damages during large scale pipeline replacement projects.

Using our proprietary camera systems, our crews can locate PE and vintage Aldyl-A pipe to provide highly accurate and detailed mapping of the gas main and its features.

From within the gas main, our camera and crawler systems can deliver a detailed visual assessment of PE pipe work to identify imperfections that may not be visible from outside the pipe.

Live gas main inspection delivers critical project planning data ahead of pipeline rehabilitation projects to improve project efficiency and avoid delays.

ULC’s camera technicians aid in leak investigation, identify corrosion, inspect welds, locate debris, identify damage and verify proper valve functionality.

INDUSTRY APPLICATIONS

Our live gas main inspection services provide gas distribution companies and gas network operators with the comprehensive visual data needed to assess 2″ to 48″ pipelines for damage and signs of corrosion, as well as resolve poor pressure issues caused by water infiltration and blockages. The information obtained from our live gas main inspection services eliminate costly guesswork, minimize excavation and prioritize maintenance activities.

ULC’s Camera and Crawler Inspection Systems enter the main using a no-blow launch tube which adapt to your mains using a variety of industry standard fitting and valve combinations including ALH Systems, weld fittings, electrofusion fittings and bond and bolt style fittings. Ahead of your project, our operations team will discuss and identify the optimal entry method for your project.

ULC Robotics’ advanced camera and crawler systems enter live gas mains through small tap holes to completely avoid the need for pipeline cut outs.

ULC ROBOTICS: EXPERTS IN LIVE GAS MAIN INSPECTIONOur highly trained field technicians operate a wide range of proprietary and patented live gas main crawler and camera inspection systems. These cameras are deployed by some of the largest gas distribution utilities throughout the U.S. and overseas markets to provide high quality, safe and reliable inspection of cast iron, steel and plastic gas distribution mains.

In addition to viewing the inspection in real-time, inspections can be recorded to DVD or digital media to keep on record. Crews have the ability to detail the inspection through written reports that detail features and anomalies in the pipe as well as their location.
