METHOD AND SYSTEM FOR MONITORING THE PERFORMANCE OF A PIPE CONTAINING A PRESSURISED FLUID

摘要

The invention relates to a method and system for monitoring the performance of a pipe containing a pressurised fluid, said pipe comprising at least one current zone and singular zones. The inventive method comprises: the static monitoring of a pre-determined number of singular zones, in order to obtain circumferential dilatation information; and the calculation of the effective stiffness K(ti) of the pipe and of the measured residual steel section As(ti) of same, using the above-mentioned circumferential dilatation information. The method can also comprise the dynamic monitoring of the pipe, in order to obtain information relating to the natural vibration frequencies and modes thereof.
