Reservatórios metálicos para armazenamento de água potável

Abstract

This study addresses the analysis of pathological manifestations in cylindrical steel tanks designed for potable water storage. The research aims to identify and examine the main structural pathologies affecting these tanks, considering design, fabrication, and maintenance aspects. To achieve this, inspections were carried out on several tanks installed in different regions of Brazil, using visual methods and non-destructive testing techniques. The results indicated corrosion as the primary cause of structural degradation, particularly in coastal areas. Furthermore, the study emphasizes the importance of rigorous inspection and monitoring during the manufacturing process of steel tanks to prevent deformations, welding defects, and other pathologies that compromise structural safety and durability. The research concludes that the absence of specific standards for this type of structure in Brazil, combined with inadequate maintenance practices, significantly contributes to the reduction of the tanks’ service life. Preventive strategies are recommended, such as the use of appropriate coatings, regular inspections, and strict quality control during fabrication, to ensure the integrity and longevity of these structures.
