Abstract

Элемент трубопровода (1), содержащий по меньшей мере одну проточную трубу (4), изолятор (3), размещенный на наружной поверхности трубы, и гофрированный наружный кожух (2), выполненный на изоляторе (3) таким образом, что элемент трубопровода является гибким по всей длине. Наружный диаметр изолятора (3) уменьшают перед его подачей в гофроагрегат (13) внутри наружного кожуха (2). В гофроагрегате (13) наружный диаметр изолятора (3) приобретает свой первоначальный размер. Свободный наружный диаметр слоя изолятора больше, чем минимальный внутренний диаметр наружного кожуха (2).
