Inspection Range

The most difficult question to answer concerning guided wave testing is the inspection range. How far can your system inspect? The answer depends strongly on the capability of guided wave system (how strongly generates torsional or longitudinal mode and how much reduces the generation of flexural modes), defect size, and attenuation (operating frequency, geometric features of pipe, corrosion condition, pipe coating, insulation, depth of burial, and the nature and degree of compaction of the surrounding soil).

In the following application, chose different inspection cases from the menu on the left to see inspection range and defect size that can be detected. Each inspection case is characterized by a specific value of guided wave attenuation in dB/m.
