Statistical Analysis of the Technical Condition of the Irrigation Pipeline of the Community of San José De La Silveria through the Measurement of Thicknesses by Ultrasound

Abstract

Wear caused by the presence of solid particles. It is essential to precisely identify the specific causes of wear caused by the presence of solid particles, because it has a negative influence on both water quality and the efficiency of the distribution system, which generates significant costs. To carry out this research, the pulse-echo ultrasonic method is used, according to ASTM E797 standard, for which the TG3000 ultrasonic equipment is used and the guidelines established by API 570 standard for the inspection and evaluation of thicknesses are followed. It is important to note that the intrinsic properties of the materials, such as propagation, microstructure dispersion and attenuation, pose challenges in the application of ultrasound as a measurement technique. Thickness measurements are carried out on 15 pipe sections, using reference points (TML) as a tool for identification. Pipe wear is determined at measurement points along a 15,000-meter inspection length. The measurement of the points along the pipeline is established at a distance between points of 1 m with respect to the total length. Then, digital statistical tools, such as R-study, are used to analyze the most prone areas that require immediate maintenance. Finally, it is concluded that the wear originating inside the pipe is due to hydro-abrasion. These findings offer valuable insight into wear mechanisms, providing a solid basis for the implementation of preventive strategies and effective maintenance, thus contributing to the preservation of the integrity and efficiency of the water pipeline system.
