Small VGC (12″-18″)

Robotic Internal Inspection Device for Gas Mains

The ULC Robotics Variable Geometry Crawler (VGC) provides gas companies with live, high-resolution video inspection of gas mains. Using the VGC, gas companies can assess the conditions of their mains as well as locate cracks, damaged pipe, unknown branches, service tees, valves, fittings and water intrusion or debris. This inspection is performed while the main remains live without any interruptions in service.

No-Blow Conditions

Developed specifically for the inspection of live gas mains, the VGC enters the main under no blow conditions. The VGC is designed to operate in pressures up to 100 psi.

Flexibility

The VGC is very flexible in its usage. The crawler can operate in pipe with diameters ranging from 12- to 16- inches.
