针对隔热层下钢管壁厚腐蚀减薄的检测问题,根据电磁涡流无损检测原理,研制出了隔热层下管道壁厚脉冲涡流检测系统。该系统可在役(不中断设备运行)检测隔热层厚度100 mm以上的钢管壁厚。
Aiming at the problem of thinning corrosion of steel pipe wall under insulation layer, a detecting system of pipe wall thickness pulse eddy current under insulation layer was developed according to the principle of electromagnetic eddy current nondestructive testing. The system can be used in service (without interruption of equipment operation) to detect wall thicknesses of more than 100 mm of insulation thickness.
