Abstract

patente de invenção: "tubo enrolado extensível". a presente invenção refere-se a um tubo enrolado extensível (200) consistindo em, pelo menos, duas tiras (210,220) enroladas em formato de espiral, que apresenta na seção lon gitudinal, pelo menos, três seções telescópicas (ta1,ta2,ta3). essas seções telescópicas, no estado comprimido do tubo enrolado estão dispostas sobrepostas axialmente, no estado estendido do tubo enrolado estão dispostas uma ao lado da outra axialmente, e em relação a uma retirada axial estão enganchadas entre si. o tubo enrolado pode alcançar um estiramento de mais que 100%. seu comprimento axial no estado comprimido, em essência, por uma das duas tiras, e seu comprimento axial no estado estendido é determinado por todas as tiras bcontidas na geometria do tubo. a fim de obter isso, durante a compressão e o estiramento, os diferentes perfis vão um para dentro do outro telescopicamente. o tubo enrolado pode ser empregado, por exemplo, em sistema de escape para o isolamento de tubulações com raios de curvatura pequenos.
