Monitoring internal corrosion of a pipeline

[chetanladha]

Hi All,

I am wondering if there is any way to monitor internal corrosion in pipelines (without using pigs and interrupting the flow)?

May be ultrasound waves could be used for this purpose, however I am not sure if it would be able to give a clear picture of extent of corrosion.

Thanks for reading.

ultrasound can show material loss, depending on the modulation of the waves used. Comparing different modes can show this.
