Abstract: This paper introduces the basic principle and signal characteristics of geometric deformation internal inspection. Based on the consistency principle of convex and concave signals, the identification techniques of pipeline body deformation and attachment abnormality are studied. The implementation risk caused by deformation defects is also analyzed, and the treatment measures are put forward. Above study is expected to provide technical support for the identification of geometric deformation signals and the safe implementation of internal inspection in the future.
