Corrosion on insulated and buried pipeline could be difficult to detect and locate. With the assistance of the technology of Transient Electromagnetic Method (TEM), utility owner and management team now can easily assess pipe wall thickness without direct contact of the detected objects.
• Average pipe wall thickness assessment on underground buried and exposed pipeline
• Pipe wall loss estimation on Insulated pipeline without damage of the existing insulation
Transient Electromagnetic Method (TEM)
By receiving signal from the secondary field (Eddy Currents), defects on material disturbed the eddy current flow and hence such disturbance provides defect location and depth.
