Abstract

Patente de invenção: <B>"TUBO TERMICAMENTE ISOLADO POR UM MATERIAL ELASTOMéRICO E MéTODO DE FABRICAçãO"<D>. A presente invenção refere-se a um método destinado ao isolamento térmico de um tubo (1), compreendendo os seguintes estágios sucessivos: -deposição, na superfície externa do tubo que se move longitudinalmente, de uma estrutura (3) de material isolante feito de elastómero tendo um comportamento do tipo elástico, substancialmente sem deformação plástica irreversível; -formação de pelo menos uma fenda circunferencial (4) na espessura do material, substancialmente ortogonalmente ao eixo (2) do tubo; -revestimento da espessura do material isolante com uma bainha vedada. Em uma variante, a fenda é usinada na espessura do isolante. A invenção ainda refere-se a um tubo termicamente isolado. A Figura 1b a ser publicada.
