Intero - The Sniffers offers a series of dedicated inspection services addressing the specific challenges of a turnaround.

Some inspection activities are executed before shutdown to identify the components that need further maintenance. To speed up the installation activities, some inspections are done during turnaround. Leak detection is also done after startup of production to minimize leaks and incidents.

Turnaround inspections techniques

Depending on the specifics of the production installation and the objectives of the turnaround, we apply the following techniques:

  • Ultrasonic inspection of steam lines and flare or vent lines, pressure relief valves or internal passing valves
  • Ultrasonic leak detection of all opened equipment resulting in a fast and accurate detection that replaces time-consuming and inaccurate soap tests or expensive helium tests
  • Wall thickness measurements of pipes or walls
  • Thermographic surveys of furnaces, cooling equipment, process components, electrical installations, under insulation components, underground pipelines, etc…
  • Leak detection with gas camera or PID/FID leak detection equipment
  • Ultrasonic leak detection on N2, compressed air, or vacuum lines

These techniques and services enable the maintenance team to focus their efforts on the key critical components. Effective inspection services guarantee fast and safe production startups.

ENV - LDAR campaign 2

We are pleased with the professionalism of the team during the startup of our plant. We were able to quickly repair several small leaks found with ultrasound measurements. When pressurizing the site, your team was present at the right location at the right time. You were able to locate a leak that remained small (within the norms) but that was invisible for us due to the insulation. Our Turnaround team wants to thank you for your pleasant and flexible work attitude. The aftercare is equally impressive. We look forward to continue using your services in the future!
