| Abstract: | This paper presents a theory of magnetic stress detection techniques,namely magnetic tomography detection technology,which is a non-contact passive detection technology.It can detect various types of defects in long-distance pipeline tube body.First,briefly addressed the detection principle,followed by a detailed inspection of the implementation of the whole process work steps,and each step of the job content,once again outlined its unique empirical calculation of MAOP and the formula of the remaining life,and then followed by the actual pilot testing as an example to illustrate the feasibility of the technology,and finally pointing out the advantages and disadvantages of the technology. |
