AbstractThe wall thickness and strength of pipeline can be reduced by corrosion and other factors during using, which may lead to leakage and other accidents. In conventional pipeline detection, the wall thickness is detected by thickness gauge. As the heat insulation layer of detection area has to be removed during detecting, the conventional pipeline detection method has the character of long detection period, high cost and limited detection area. By using PFC-2000 ray pipeline detector, pipeline can be rapidly detected by scan mode without remove heat insulation layer. And, the detection results have nothing to do with the media in the pipeline. By PFC-2000 ray pipeline detector, can location corrosion point and comprehensive evaluation the pipeline corrosion condition. The application scope and detection accuracy of PFC-2000 ray pipeline detector were developed by experiment research and technology upgrade, which lead to the development of pipeline detection technique.

AbstractTo overcome the shortcomings such as inspection instruments and methods for corrosion on outside wall of tubing which used in oil wells, a magnetic inspection method is present. Dual polarity low-frequency pulse is used to excite the coil instead of transitional sinusoidal signals. A time-domain analysis method called “time slicing method” is utilized for detected signals processing, good testing results are present by inspect for simulate outside corrosion on tubing; the relative errors between calculated value and the actual value of tubing wall thickness are very small. Experimental results show that corrosion on outside wall of tubing can be detected and the average value of residual wall thickness of tubing can be given more accurately by the method.

AbstractPulsed eddy current (PEC) testing technology is a burgeoning electromagnetic nondestructive testing technology, eddy current penetration depth and the senstitivity have a close relationship with excitation parameters, appropriate excitation parameters is very necessary. The finite model of circular probe using COMSOL is built on subsurface defect with different peak of excitation, different duty cycle of excitation and the same integral of amplitude on the time. After simulation, increasing the peak of excitation can get better sensibility and the duty cycle can decide the penetration depth through data analysis of Matlab. The conclusion will provide some references on subsurface defect detection.
