Dear Abbas,

Please could you provide us some more details about the job? drawings, items to be inspected, proposed inspection equipment etc?

Thanks,

Prasad

Dear Abbas,
I think Guided Wave might be a good solution for corrosion mapping. In addition, by using low-cost magnetostrictive sensors you can distribute them on your piping and leave them there for further inspection. This way you can do not only one corrosion mapping, but also long-term monitoring to see slight changes in pipe-wall condition.
For further details, please contact me, or visit our site: www.guidedwave-ndt.com

Florin Turcu

Abbas if this is new to you maybe you should discuss with the equipment vendor. 6 mm nominal is relatively thin and if you get 50% wall loss then we are talking 3 mm or less so selection of the correct transducer will be critical.
Step one is to talk to the relevent corrosion specialist about the corrosion morphology expected and the expectation sof the survey in terms of thickness and area resolution. This will determine not only probe selection but also the spatial resolution of your scanner - remember you probably need three hits per pixel increment to be confident true corrosion detection - this is of course is related to beam spread, PRF and grid increment.
Step two - whats on the outside of the pipe and are you going to measure pulse to first BWE or do you need echo to echo to remove coating thickness.
Step three - what post processing do you want to do - are you going to record gated signals or full waveform capture.

From these you should be able to construct a procedure.

Good luck
