Advanced ultrasonic NDT solutions for precise structural integrity verification.
Sonomatic Inspection Services
SCT (Stress Concentration Tomography) is the only inspection technique in the world capable of mapping the lateral position and depth of cover of pipes while providing comprehensive defect detection.
Developed by Speir Hunter Ltd., this technology utilizes the physical relationship between stress and magnetization. Local stress changes in the pipe wall—due to corrosion, ground movement, or mechanical defects—create predictable changes in the natural magnetic field. SCT reads these signals from a distance to determine the location and magnitude of the problem.
High Accuracy with UNISCAN™
Advanced ultrasonic NDT solutions for precise structural integrity verification.
Sonomatic Inspection Services
- Sensitive Magnetometer Array: Collects natural magnetic field data from pipes remotely (above ground).
- Precision GNSS System: Marks magnetic data with real-time location coordinates for mapping accuracy.
- Advanced Firmware: Records data into the system for further analysis using specialized algorithms.
A Flexible and Diverse Tool
SCT™ has been designed as a cost-saving addition to existing methods of inspection and it can be used in a variety of ways. Weighing less than 8kg and requiring only a 2-man team to operate in the field, UNISCAN™ is rapidly mobilised and can be deployed in many different environmental conditions.
