Eliminate Gas Pipeline Third Party Damage: In-Pipe Locating

In-Pipe Locating: Eliminate Pipeline Third Party Damages

Using our specialized equipment, ULC Pipeline Robotics works with utilities to pinpoint the exact location of gas mains along with all pipeline features—even those not traceable by traditional locating methods.

In-Pipe Locating: Key Benefits

01. Eliminate Pipeline Third Party Damage

In-Pipe Locating produces the most accurate and complete mark out that contractors need to avoid damages while excavating alongside or around gas mains.

02. No Need to Rely on Outdated Mapping

Negate the need to rely on outdated and inaccurate gas utility maps that are often the cause of damages to mains.

03. Confident and Efficient Excavation

ULC Robotics’ operator qualified crews provide contractors with the information they need for reliable and efficient excavation near gas mains.

04. Stub Service Locating

In-Pipe Locating pinpoints the location of connections to the gas main, including stub services, tees, crosses and service taps whether or not they are on the map.

05. Effective with all Types of Gas Mains

Our proprietary equipment and software allows In-Pipe Locating to be extremely effective on all types of metallic and plastic gas distribution mains including Aldyl-A and double thick walled steel mains.

06. Highly Accurate GPS Integration

ULC Robotics developed a means of providing precise GPS coordinates of the gas main and its features. GPS coordinates can be used to update utility maps or accurately recall the location of a feature.

How it Works


ULC crews utilize proprietary live gas main inspection equipment to visually inspect the main and identify features inside that excavation contractors will need to avoid.

Gas utility third party damage

In the main, the camera is positioned under a specific feature such as a tap hole or tee, and then a second technician will pinpoint the location of the camera from above ground. Unique radio frequencies from the camera can be detected through PE, cast iron and steel pipe material.

Once the position of the main or feature is pinpointed, the highly accurate location is marked out and measurements from the curb are noted in the field reporting. Sub-centimeter GPS locations of these features can also be obtained for integration into GIS.

In-Pipe Locating Applications: Eliminate Gas Pipeline Third Party Damage

Eliminate Third Party Damage During Mains Replacement Programs: In-Pipe Locating can provide excavation contractors with the accurate and complete mark out information they need to avoid damaging mains and pipeline features during replacement.

Unlocatable Aldyl-A and Plastic Mains: Our locating service is an ideal solution for locating buried plastic gas mains, including Aldyl-A, where there is no tracer wire or the tracing wire is broken.

Remapping Gas Mains: In-Pipe Locating can be utilized to update utility mapping that is known to be outdated, incomplete or missing to ensure data is accurate.

Identifying and Locating Features: ULC Robotics is contracted to perform In-Pipe Locating in newly installed mains to pinpoint the location of couplings and verify the installation of service tees.
