Zusammenfassung:PROBLEM TO BE SOLVED: To provide a pipe inspection method and a pipe inspection device which can accurately detect the center position of a pipe even in such a state that a heat insulating material is wound around an outer surface of the pipe, so as to be able to improve the accuracy of thickness measurement.SOLUTION: In a pipe inspection method, after the deviation of the center of a pipe (1) inside a covering material is measured from a plurality of different directions by using a radiation having linearity, the thickness of the pipe (1) is measured on the basis of a center position (O1) of the pipe (1).SELECTED DRAWING: Figure 1 【課題】配管の外面に保温材等が巻かれた状態であっても配管の中心位置を精度よく検出することを可能とし、肉厚測定精度を高めることができる配管検査方法、及び、配管検査装置を提供することにある。【解決手段】本発明の配管検査方法は、直線性を有する放射線を用いて、被覆材内部での配管(1)の中心ずれを、複数の異なる方向から測定した後、前記配管(1)の中心位置(O1)に基づいて前記配管(1)の肉厚を測定する、ことを特徴とする。【選択図】図1
