摘要： PROBLEM TO BE SOLVED: To solve problems such that exfoliation and laying defects of polyethylene lining, which are applied inside the piping of an atomic power plant, and difficult to detect in its early stages because a visual inspection of lining exfoliation and condition thereof can be only conducted when piping spools are disassembled during regular inspections, and working hours of the plant regular inspections need much time for the piping inspection which are required to be reduced.
SOLUTION: By emitting ultrasonic pulses to a pipe wall from a bent portion of the pipe, a reflected echo from the interface between the pipe and the lining and a reflected echo from the surface of the lining can be detected. When exfoliation of the lining occurs, the reflected echo from the surface of the lining cannot be detected, and thereby the condition of lining can be examined from the outside of the piping during plant operation.
