Signals acquisition and processing for corrosion control in carbon steel pipelines used for potable water supply

Abstract

This work deals with the monitoring of physical variables influencing the corrosion process suffered by SAE 1018 carbon steel pipelines used for potable water supply in a region of Hidalgo State, Mexico, by means of a data acquisition card (DAQ) from four sensors: conductivity, pH, chloride concentration, and temperature, and supported by a graphical user interface through LabVIEW 9.0. The obtained main results show the potable water is not the cause of the possible faults or cracking in the carbon steel pipelines.
