Abstract

resumo tubo de parede dupla termicamente isolada e respectivo método de soldagem, compreendendo um método de soldagem, para reduzir a tensão devido ao alongamento da tubulação, para um tubo isolado de parede dupla (4) utilizado em poços de petróleo; o referido tubo (4) compreende um tubo interno (1), um tubo externo (2), anéis espaçadores de aço (8) e material isolante (12) como preenchimento do espaço anular (3), sendo que a soldagem liga as extremidades dos tubos interno (1) e externo (2), formando uma junta metálica flexível, obtida através do uso de metal de adição com composição química específica durante o processo de soldagem; dito tubo interno (1) é aquecido e dilatado antes da soldagem do tubo ser realizada, resultando em uma junta soldada é resistente o suficiente para manter o tubo interno (1) no lugar quando esfria, criando uma tensão para dentro no tubo e, desta forma, quando o vapor flui através da tubulação durante a operação, o calor dilata o tubo interno (1) até que a direção da tensão seja para fora, então a tensão agora se torna cerca de metade da tensão normal que seria aplicada a esta junta soldada se fosse utilizado o método de soldagem usual.
