Guided wave ultrasonics are utilized for the rapid scanning of large volume of piping systems. Guided wave utilizes a ring of transducers that is place around the pipe and emits sound waves that are sent along the pipe in both directions from the ring. Many feet of pipe may be inspected at one time, depending on a variety of factors including surface condition, the presence of pipe wrap systems and mechanical features such as elbows etc... Guided waves are best used as a screening tool as part of a more comprehensive strategy that pinpoints where more extensive volumetric examinations should be performed.
