Abstract

a presente invenção refere-se a um processo para produção de tubos bimetálicos, consistindo em um tubo interno de parede fina de aço de alta liga ou aço ligado e um tubo externo de aço não ligado ou aço sem liga que, depois de serem inseridos um no outro, são ligados um com o outro com fecho devido à forma por meio de alargamento sob aplicação de pressão interna, bem como a um dispositivo para a execução do processo com cabeças de vedação (3) que podem ser encostadas nos tubos (1; 2) a serem alargados para a alimentação de fluido de pressão. o dispositivo é caracterizado pelo fato de que na cabeça de vedação (3) é prevista uma fixação (5) possuindo uma saliência (7) apontando radialmente para dentro, para a fixação do tubo interno (1, 1') a ser alargado, que pode engrenar com uma ranhura circunferencial (6) no tubo interno (1; 1').
