DESENVOLVIMENTO DE UM RESERVATÓRIO EM PRFV DE 25 M3 PARA ÁGUA POTÁVEL

Abstract

The present work presents the development of a vertical cylindrical tank with a capacity of 25 m³, manufactured from Fiberglass Reinforced Plastic (FRP), intended for the storage of potable water. The main objective of the project was to design, manufacture, and test equipment that complies with the ASME RTP-1, ASTM D3299, ASTM D4097, and ABNT NBR 16098 standards, ensuring structural safety and compliance with potability requirements. To this end, manual lamination, spray-up, and filament winding processes were applied, in addition to performing quality tests such as Barcol hardness, ash content, leak tightness, and acetone sensitivity tests. The design report considered hydrostatic and wind loads according to ABNT NBR 6123, ensuring the structural integrity of the shell and heads. The results demonstrated that FRP is a technically feasible alternative to the replacement of metallic materials, presenting high mechanical strength, low density, and excellent corrosion resistance. The study provided technical and practical advancements, highlighting the potential application of composite materials in the manufacturing of tanks for industrial and sanitation use
