Objective
The object of the project is to study construction and testing of a low-cost self-destroying instrumented vehicle destined for the maintenance control of pipelines (corrosion monitoring).
Fragmentation tests with a pyrotechnical system have shown that all remaining parts of the equipment were less than 25% of the pipe diameter.
The electronics for corrosion monitoring are composed of :
* a micro-computer to control the measurement systems and the data processing
* a real time clock for the referencing and which can also be used for fragmentation programming
* the measurement electronics and analog conditioning
* a high-capacity CMOS RAM module.
Calibration tests were perfomed on a pipe test whose defects were known, a phase shift of 5 degrees represented an attack of 3% of pipe wall for general corrosion.
The tool developed by SYMINEX will operate in a 12" diameter pipe in a 10 to 20 km length line. It is made of "syntactic foam" and could be destroyed by a pyromechanism if it is jammed for a long time in the pipe. In addition, a magnetic sensor gives information about the corrosion of the pipe. The data acquisition and storage are managed by an on-board microcomputer.
