Overview

Guided Wave Testing (GWT) uses low-frequency ultrasonic waves that propagate along the length of a structure (typically piping) to screen for corrosion and defects over long distances from a single probe position. This technique is particularly valuable for inspecting insulated, coated, elevated, or buried piping where conventional inspection methods would require extensive preparation.
