Summary:A method for detecting the defect of the pipe includes the steps of: detecting a first parameter related to a magnetic induction intensity along a length direction of the pipe; determining whether the first parameter exceeds a predetermined threshold; determining a position at which the first parameter exceeds the predetermined threshold as the position of the defect of the pipe; and determining a degree of the defect of the pipe based on a numerical value of the first parameter exceeding the predetermined threshold. Through the detecting device, the defect in the pipe is decided based on parameters related to the magnetic induction intensity, the position of the defect of the pipe is determined according to a position at which the parameters are abnormal, and the degree of the defect of the pipe is determined according to numerical values of the parameters which are abnormal.
