Hello   You can use a NDT technique called ultrasound guided waves (UTGW)   This technique can detect a serious kind of defects in pipelines, internal and external. Depending of pipe conditions, this NDT can inspect even 50 meters of pipeline in just one test.   As is based in ultrasonic principle, this use longitudinal and torsional waves to detect indications which are categorized quantifying the transversal loss of area in pipe. As complement, then you can use single beam of ultrasonic thickness measure to check any indication   This can be used with pipeline in service   Attached you can find a little information about this NDT   There are a lot of services in NDT which offer this one   Regards        Miroslav   Tadic Ingeniero  de Integridad CEE Gerencia de Producción - Mantenimiento YPFB Chaco S.A.
