The present invention will be described in detail below with reference to the accompanying drawings.
The invention adopts a magnetic flux leakage detection method to carry out wall thickness monitoring and defect detection: the measured section of the continuous tube reaches a magnetic saturation state by applying a constant magnetic field outside the continuous tube. If the inside of the pipe body has the defects of cracks, holes, pores, corrosion pits and the like, a leakage magnetic field is formed outside the pipe body; if the wall thickness of the pipe body is reduced, the magnetic induction intensity in the magnetic field loop slightly changes. The magnetic sensitive element is adopted to synchronously move along with the exciter and scan a defect area by measuring the change of the leakage magnetic field and the magnetic induction intensity outside the continuous tube body, so that electric signals of the defects can be obtained, then the signals are sampled, conditioned, subjected to A/D conversion and analyzed, qualitative analysis and quantitative judgment can be carried out on the defects, and further data such as the condition, the position relation and the like of the defects of the continuous tube are measured and evaluated.
