Title: Pipe inspection method
Inventor: OKA MASAAKI
IPC: G01N29/26
Filed: 2008-09-05
Abstract: <P>PROBLEM TO BE SOLVED: To provide a pipe inspection method for accurately inspecting whether or not the thickness of a pipe has decreased even when the pipe is a large diameter one in a high-temperature state.  <P>SOLUTION: This method for inspecting thickness decrease of a high-temperature pipe includes a probe disposition step for bringing an ultrasonic probe into contact with the surface of the pipe via a contact medium for high temperature, and an inspection step for moving the ultrasonic probe along the axial direction of the pipe with the probe kept in contact with the surface of the pipe. Even when an inspecting object is a high-temperature pipe, the ultrasonic probe can be prevented from being damaged by heat while thickness reduction and the like can be inspected. Since a plant installation equipped with a pipe which is an inspecting object can be inspected without halting it, maintenance and inspection on the pipe can be inspected periodically at relatively short intervals.  <P>COPYRIGHT: (C)2010,JPO&INPIT
