Heat networks are used by cities and communities for heating purposes. Pipeline diagnosis aims to detect defects and anticipate leaks to ensure safety and greater continuity of service for the Group’s customers. The
Pipeline diagnosis: An essential safety measure
With time, water seepage, natural ground movements and surface or underground construction work, the buried pipes of the heat networks can deteriorate (corrosion, erosion, etc.), resulting in leaks.
What is the purpose of remote diagnosis?
The Group’s R&D team along with Ecole Centrale de Lyon has devised a new remote inspection method, through guided waves. Simulations showed that it should be possible to detect and locate defects on a pipeline from a distance of nearly
How does it work?
A wave signal is emitted on either side of an accessible point on the pipeline and the reflected signals are collected and analyzed. In the event of a defect in the pipeline, the reflected signals emit an identifiable distortion, capable of indicating the potential presence of a defect (thinner area, cracks etc.), its nature and its location.
