Pipelines are susceptible to damage from internal and external corrosion, cracking, manufacturing flaws, and other third-party damage. The leakage of contents into the channels could be harmful to the environment, especially if the pipes are carrying gas or chemicals.
This inspection of pipelines could range from visual inspection to non-destructive testing. Non-destructive testing (NDT) includes a variety of analysis techniques to assess the properties of the materials without causing any damage to the material in the process. Some tools used in performing NDT of pipelines utilize X-rays, magnetic particles, and ultrasonic sound waves.
