GUIDED WAVES: STANDARDIZATION AND CERTIFICATION

The Guided Wave Testing (GWT) Method is a new NDT Method, which is typically used for rapi d screening of lo ng lengths of pi pe-work. One of the main attractions to this method is its ability to screen relatively long length of pipe from a remote location (avoiding the need to directly access the area to be inspected). GWT is now widely recognized and is the preferred NDT method when other a pproaches are not very effecti ve. This article summarizes the effort that has recen tly been made to qual ify the method, standardize the inspection approach and certify the personnel that carry out the inspection. This work aimed to provi de confidence to the i ndustry that appropriate GWT tools can be used by qualified operators to pr operly assess their assets.
