Determinación del estado técnico de las tuberías de los tanques de almacenamiento de agua potable del GAD parroquial rural de Licán mediante ultrasonido.

Abstract

The determination of the technical state of the conducts of the drinking water storage tanks of the rural parish GAD Licán was carried out by means of ultrasound. To develop this investigative work was investigate on thickness measurement by means of ultrasound non-destructive testing techniques, used the ASTME797 standards, practical guide for measuring thicknesses with ultrasound the AWWA C 150 standard for the design of thicknesses required in water pipes, conventional water, and the API 570 for wear that occurs in the pipes through the procedures for the inspection and evaluation of the condition of the pipes that are subjected to the ultrasound test through the measurement of thicknesses, allowing to calculate the speed of wear and useful life. To measure the thickness, Benetech GM130 5MHz equipment was used. In the development, the coding and the technical data sheets of the storage tanks were elaborated, then the thickness was taken in the entrance, exit and exhaust connections of galvanized steel, with which performed a statistical analysis and technical, that a determine thickness the maximum, average, minimum and low points in the ABCD areas of the cross section of the pipes. once the data obtained from the measurement of thicknesses have been analyzed, it was found that at the top of the pipe (point A) you have the greatest wear, which has analyzed the loss of material due to deterioration, is mechanical - corrosive type, in addition, the wear speed was calculated, the service life and the next inspections in the pipes were to finalize with the elaboration of the final inspection reports in the 9 storage tanks. It is recommended to perform an analysis of the pipes with less useful life, based on the wear rate for the planning of maintenance tasks and to take as a basis this work for the analysis of similar systems with galvanized steel pipes in others sectors of the province.
