Guided wave inspection of pipelines is now in routine use worldwide.
The technique offers the possibility of rapid screening of long lengths of pipework for corrosion and other defects.
A test range of 50m or more (25m in each direction) is commonly obtained from a single transducer position.
Long range guided wave inspection techniques are also in development for several other applications, including
the detection of corrosion in large areas of plates, the detection of cracking in railway lines,
the detection of cracking in rockbolts, and the detection of corrosion in heat exchanger tubing.
