DEVICE AND METHOD FOR MONITORING THE THICKNESS OF A THERMALLY INSULATED FERRITIC STAINLESS STEEL PIPE BY REMOTE MEASUREMENT

摘要

The invention relates to a device for monitoring, by remote measurement, the thickness of a wall of a heat-proof ferritic stainless steel pipe (1) partially subject to erosion-corrosion, characterized in that the device includes: at least one flexible film (11) for network sensors placed against the outer wall of at least one section (2) of the pipe (1) and under a heat insulator (3); a control housing (15) connected to the sensors of said at least one flexible film (11) and placed outside the thermal insulator (3); and a measuring apparatus (20) connectable to the control housing (15) to periodically query the sensors and compare the measured thickness values of the wall of said at least one section (2) with a boundary value indicating a high rate of thickness decrease that is not to be exceeded by the pipe (1).
