Abstract
a presente invenção refere-se a um conjunto do tipo tubo em tubo que compreende espaçadores termicamente isolantes (24) posicionados em uma coroa anular (16) para agir radialmente entre os tubos interno e externo (12, 18). os espaçadores compreendem pelo menos uma disposição circunferencialmente estendida de nervuras circunferencialmente espaçadas (26) que definem passagens longitu-dinalmente estendidas nas aberturas (28) entre as nervuras vizinhas da disposição. cabos (10) que incluem elementos de aquecimento es-tendem-se longitudinalmente ao longo da coroa anular fora do tubo interno. os cabos estendem-se longitudinalmente ao longo das passa-gens. pelo menos uma camada de isolamento (48, 52) disposta radi-almente fora dos cabos compreende elementos isolantes dispostos nas aberturas entre as nervuras e/ou uma camada isolante que se es-tende em torno do tubo interno, posicionada radialmente fora das ner-vuras e unindo as aberturas. faixas circundam e retêm componentes da camada de isolamento. o isolamento também pode ser disposto no tubo interno entre as primeira e a segunda disposições das nervuras, em que essas disposições são espaçadas longitudinalmente uma da outra.
