Robotic non-destructive testing (NDT) is a method of inspection used to assess the structural integrity of petroleum, natural gas, and water installations. Crawler-based robotic tools are commonly used for in-line inspection (ILI) applications in pipelines that cannot be inspected using traditional intelligent pigging tools (or unpiggable pipelines).
A "pig" is a tool that is sent down a pipeline and propelled by the pressure of the product flow in the pipeline itself. There are four main uses for pigs: Physical separation between different fluids flowing through the pipeline; Internal cleaning of pipelines; Inspection of the condition of pipeline walls (also known as an inline inspection ...

The most recent was the 2010 San Bruno pipeline explosion that killed at least four people, injured 60 and more victims are still missing. [19] Portions of the San Bruno pipeline had been built in 1956. In ideal situations, pipeline inspection gauges or a “PIG” (see Pigging) is used to inspect and ensure the safe operation of natural gas ...
The method employs acoustic waves that propagate along an elongated structure while guided by its boundaries. This allows the waves to travel a long distance with little loss in energy. Nowadays, GWT is widely used to inspect and screen many engineering structures, particularly for the inspection of metallic pipelines around the world. In some ...
