RAI has just completed a 2 week contract assisting another NDT company in performing GUL inspection on a live petrochemical refinery.
GUL or “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.
Utilizing the tried and tested system of RAI, the job was able to be completed in less than half the time it would have taken with scaffolding and with zero injuries of near misses, this once again is a testament to the safe working conditions employed by Rope Access Inspection (RAI). Well done to the A-Team for making this a successful contract.
