<p>The invention relates to an installation for monitoring and tracing the flaws in the pressurized fluid transport piping with a constant diameter and without branching. According to the invention, the installation for monitoring the pressurized fluid transport piping eliminates these disadvantages by mounting, lengthwise of the pipe (2) a series of pressure transducers (1) which sense any deviation from the operating parameters of the transport installation and transmit signals to a monitoring and surveying system which indicates the flaw location. Upon the occurrence of a flaw on a pipe (2), the pressure varies and it is sensed by the pressure transducers (1) which emit an analogous signal converted into a digital signal by means of some sampling-memorizing circuits (EM1 ... EMn), of some convertors (CAN1 ... CANn) and amplified by signal amplifiers (A1 ... An), these circuits being controlled by programable control automata (APC1... APCn), piloted by tact generators (GT1 ... GTn).</p> |
