PROCESS FOR CLEANING, INTERNAL REPAIR AND VERIFICATION OF THE MECHANICAL INTEGRITY OF ABOVEGROUND AND UNDERGROUND STORAGE TANKS FOR FUELS AND INDUSTRIAL APPLICATIONS

Abstract

The present invention consists of a comprehensive technical process for the cleaning, internal repair, and verification of the mechanical integrity of storage tanks, applicable to both aboveground and underground tanks used in gas stations, service stations, and industrial facilities. The process integrates, in an orderly and sequential manner, specialized technical stages that include tank preparation, internal cleaning, visual inspection, ultrasonic inspection, internal mechanical repair, and subsequent verification of mechanical integrity, allowing for an objective evaluation of the tank's structural condition before its return to operation.Unlike traditional methods, this invention combines the precise detection of structural damage with internal corrective actions and subsequent technical validation into a single continuous process. This reduces operational, environmental, and safety risks, and ensures that the tank meets pre-established technical acceptance parameters. The invention results in a reproducible, verifiable, and industrially applicable method for determining the safe operational fitness of storage tanks, extending their service life, and minimizing mechanical failures associated with corrosion or material thickness loss.
