A practical method is presented that uses guided wave techniques for sludge and blockage detection in long-range pipelines. Existing techniques have the limitations that the sludge position needs to be known a priori and the area to be inspected needs to be accessible. Two guided wave techniques have been developed
ABSTRACT. The possibility of using ultrasonic guided waves for detecting and perhaps characteriz- ing, the sludge or blockage inside pipes is investigated. The presence of a an internal layer in contact with the pipe wall modifies the characteristics of the guided modes which can propagate in the clean pipe. By measuring

29 Mar 2017 A new method is presented that uses guided wave techniques for sludge and blockages detection in long-range pipelines.

Two guided wave tech- niques have been developed which allow the the sludge or blockages to be detected remotely without the need to access the specific location where the pipe is blocked, nor to open the pipe. The first technique measures the reflection of guided waves by sludge or blockages which can be used to
