Guidedwave's pigging technology utilizes circumferential guided waves to detect corrosion, cracking, and coating disbondment in pipes.
Guidedwave's pigging technology utilizes pairs of non-contact EMAT transducers.
The series of circumferential guided wave scans shown here illustrate the capability of Guidedwave's pigging technology to detect cracking and coating disbondments in pipes.
Example of guided wave pigging technology signals in a clean pipe versus a pitted section of pipe.
