METHOD AND SYSTEM FOR INSPECTING JOINTS IN COMPOSITE PIPES AND COMPOSITE REPAIRS IN METAL PIPEWORK

摘要

The present invention relates to techniques for inspections of joints and repairs in pipework. In this context, the present invention provides a method for inspecting joints in composite pipes and composite repairs in metal pipework, which comprises the steps of (i) emitting a series of acoustic-wave pulses, at different frequencies, from an acoustic-transducer collar (4) positioned at a predetermined distance from the joint (5) or repair (1) to be inspected, (ii) recording, over a time interval after emission, the echoes of the movements of the waves to the repair or joint at each of the transducers of the acoustic-transducer collar (4) in A-scan form and (iii) generating a plan-view C-scan image, using the CSM method, for each frequency at which pulses are emitted from the acoustic-transducer collar (4). The invention further provides a system for inspecting joints in composite pipes and composite repairs in metal pipework associated with the above-described method.
