摘要:
传统无损检测技术用于检测绝缘及带绝缘包覆油气管道缺陷时存在较大局限性。通过理论分析电场线和仿真模型电势线扰动规律,提出了检测绝缘及带绝缘包覆油气管道缺陷的电容成像无损检测技术,并构建了一整套基于电容成像检测原理的检测系统。试验研究结果表明:电容成像检测技术可用于绝缘(玻璃钢)油气管道中的表面缺陷和隐藏缺陷检测,也可用于带绝缘包覆油气管道中的绝缘层缺陷和金属层缺陷检测。本文研究成果对于保障油气管道运行安全具有指导意义。
Abstract:
Conventional NDT technologies have great limitations in inspecting insulating and insulation coated oil and gas pipelines. Based on theoretical analysis of electric field lines and simulation model potential lines disturbance, ECT(electrical capacitance tomography)non-destructive testing technology was put forward to inspect insulating and insulation coated oil and gas pipelines, and a full set of inspecting system based on ECT inspection principles was established. Experimental research results show that ECT inspection technology can be used to inspect the surface defects and hidden defects of insulating(glass fiber reinforced plastic)oil and gas pipelines, as well as to inspect the defects of insulating layer and metal layer of insulation coated oil and gas pipelines. The research results are of certain guiding significance for assuring the operation security of oil and gas pipelines.
