Abstract:

We have now built systems that will perform NDE inspections of (a) the body and (b) the seam weld of new and used electric-weld coiled carbon steel tubulars. The full-body inspection system provides four functions: OD and ovality measurement, internal and external imperfection detection and assessment and wall thickness measurement, all by non-contact measurements. The magnetising system places a high magnetic field across the seam weld and searches for either flaws or permeability variations there-in. Advanced forms of data processing are used to image the magnetic flux leakage (MFL)(1) from wall anomalies. Systems may be built into coiled tubing (CT) rigs, and can be configured to add fatigue models(2), so that fatigue loss due to tubing defects can be assessed.

Two systems are in operation in CT mills, while one operates for a commercial oil country tubular goods (OCTG) inspection company. Results from inspections using these tools are presented.
