Análise e diagnose da corrosão nas estruturas metálicas das torres de telecomunicações

Abstract

The present work has the objective of studying the influence of corrosion on telecommunications towers, analyzing the corrosive media that influence the deterioration of the material, also analyzing the geometry of the parts that compose the structure and verifying the behavior of the corrosion in relation to the Material that is Manufactured. Thus, in the beginning, bibliographical researches on the subject were carried out. Then visual inspections were made to observe the state of the structure and also to point out places that are facilitators of corrosion. Soon after the visit was conducted field test to simulate a real influence of the corrosive media in which as telecommunications towers are subjected. A laboratory test was also performed, in which the test specimen was subjected to a saline solution so as to check the mass loss of the material. With the obtaining of the results it was possible to notice that the telecommunications towers are subject to degrading action of the corrosion, in this way it is necessary to the application of a system of anticorrosive protection adequate to prevent propagation of the product of corrosion in the structures in general
