A tool the size of a fire extinguisher rides inside the pipe with the gas and reads the wall from the inside.
Switching off a pipeline to inspect it means a factory stops. So we use a smart pig, a tool pushed along the line by the gas itself.
What it measures
The tool carries magnetic and ultrasonic sensors. Every centimetre of the pipe wall is scanned: thickness, corrosion, hairline cracks, even dents from shifting ground.
Why it matters
- Customer supply is never interrupted
- Problems are found years before they could become leaks
- Repairs are planned at the exact spot, not along the whole line
The scan reaches the control room within hours, with a map of every point to watch.
