Live Gas Service Inspection


Live Gas Service Line Inspections

ULC Technologies works with some of the largest gas networks to conduct live gas service line inspection services; delivering detailed reporting and real-time video.

Our inspection services support pinpointing issues for repairs or replacement programs, mapping out features along the service and identifying material changes. The information obtained from our live gas service line inspection services eliminates costly guesswork, eliminates unnecessary excavations and prioritizes maintenance activities.

Comprehensive Pipeline Integrity and Visual Inspection Data

Verify PE Pipe Work


Our crews can verify PE pipe work across multiple colors. We can identify and locate fusions in support of contractor QA/QC programs.

Identify Copper

New Copper
Our trained field crews are easily able to identify characteristics in copper material to assist in replacement efforts.

Locate Couplings & Fittings


Able to pinpoint couplings and fittings, our inspections support of integrity management and mapping efforts.

Identify Steel

New Steel Roll Mark
Inability to differentiate copper and steel services can lead to unnecessary, disruptive excavations. Our inspections enable easy identification of steel characteristics.

Map Out Gaslight Tee Installations

Our inspections help easily identify and pinpoint old gas light tees to support integrity management and mapping.

Visible & Audible Ferrous Detection

What We Provide

Enhanced Video Quality

The high definition camera delivers in-pipe intelligence up to 160ft out from the riser valve and can easily traverse through common valves and fittings. Data delivered by our teams’ inspection services enable the identification of different pipe materials such as PE, Copper and Steel, in addition to supporting mapping efforts and verifying features such as fusions, fittings and gas light tees.

No-Blow Entry Method

Our service line inspection systems enter services up to 60psi using a custom no-blow launch tube. Our launch methods adapt to your services using a variety of industry standard fitting and valve combinations. ULC’s highly trained and operator qualified technicians install the no-blow launch tube directly to the riser valve at the meter set.

Experienced Field Crews

Our field crews bring years of experience and expertise in live gas distribution inspections including over 35 operator qualifications for inspection work alone. This background enables our teams to deliver high-quality assessments, feature identification, accurate reporting and detailed mapping. 

Detailed Reporting & Data

In addition to viewing the inspection in real-time, inspections can be recorded and saved as digital media to keep on record and share. Crews can also provide written reports, breaking down the inspection in detail, including any features or anomalies in the pipe as well as their location.
