Who provides nondestructive testing services for oil and gas pipelines?

Nondestructive testing (NDT) services for oil and gas pipelines are provided by specialized inspection companies, pipeline integrity contractors, and some large industrial inspection firms. They use methods such as ultrasonic testing (UT), automated ultrasonic testing (AUT), radiographic testing (RT), magnetic particle testing (MT), liquid penetrant testing (PT), phased-array UT (PAUT), time-of-flight diffraction (TOFD), and corrosion mapping to evaluate pipelines without damaging them.
