摘要
对原Ф16-76mm钢管涡流探伤设备进行改造，增加了饱和磁化和退磁装置、更新了仪器、制作了新探头、改进了工艺参数，达到了既能检测不锈钢管又能检测碳合金结构钢管的目的。按GB／T7735-1995标准的B级验收，系统综合性能指标符合YB4083—2000标准规定的要求，为锅炉、电站用无缝钢管提供可靠的涡流检测设备。
The original eddy current equipment for the steel tubes with diameters of Ф16-76 mm was improved including outfiting saturation magnetization and demagnetization equipment, renewing instrument, redesigning probe and improving technical parameters to meet the requirements of eddy current inspection of both stainless steel tubes and carbon alloy structure steel tubes. It was shown by checking and accepting the inspection using the equipment according to level B in standard C-B/T 7735-1995, that the comprehensive properties of the equipment conformed to the requirements stipulated in standard YB 4083-2000. The equipment renovated provided reliable eddy current inspection of the seamless tubes used for boilers and power stations.
