Abstract

TUBO DE TRANSPORTE DE FLUIDO. A presente invenção refere-se a um tubo de transporte de fluido que compreende pelo menos uma camada interna (3), uma camada de proteção externa (5), e um dispositivo regulador de temperatura intermediário (10) conectado em uma fonte de voltagem e adequado para aquecer o fluido transportado na direção de uma temperatura de equilíbrio ou de referência pela utilização de um termistor de coeficiente de temperatura positivo (12) que apresenta uma resistência elétrica que é automaticamente controlada pela temperatura e que está conectada na fonte de voltagem (V) através de pela menos dois elementos condutores (14, 15) que fornecem a corrente necessária para aquecê-la, o tubo sendo caracterizado pelo fato de que cada elemento condutor (14, 15) é um fio metálico que está sustentado por uma camada têxtil (17) enrolada ao redor da camada interna (3) do tubo, e de que a dita camada interna (3) está baseada: em pelo menos um elastómero; ou em pelo menos um elastómero termoplástico selecionado do grupo que consiste em ionómeros e elastómeros termoplásticos baseados em olefinas que tem uma fase de elastómero de ligação cruzada.
