Abstract
The original eddy current equipment for the steel tubes with diameters of 16~76 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 GB/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.
