ABSTRACT:
The invention relates to apparatus and a method for detecting the condition of the material of a pipeline wall. The apparatus includes means for inducing and detecting magnetic flux at a location on the pipeline and, at said location, sensing means detect whether any change in material condition is on or near the external wall of the pipeline. By analysing the two sets of monitored values a change in condition, such as corrosion, can be detected, located and determined to be at or near the external or internal surfaces of the pipeline wall.
