Claims (21)
1. Способ производства изолированной трубы в гофрированной оболочке (100), включающий в себя этапы, на которых:
a) покрывают пленкой (106) внутренний трубный узел (105), содержащий по меньшей мере одну внутреннюю трубу (101);
b) заполняют расширяющимся изоляционным материалом (102) в жидком состоянии пространство между внутренним трубным узлом (105) и пленкой (106), образуя тем самым исходный трубный узел (107), содержащий слой расширяющегося изоляционного материала (102а), расположенный между пленкой (106) и внутренним трубным узлом (105);
c) экструдируют слой внешней оболочки (104) на исходный трубный узел (105) до того, как произойдет полное расширение изоляционного материала, образуя тем самым все еще расширяющийся узел изолированной трубы (118); и
d) пропускают все еще расширяющийся узел изолированной трубы (118) через гофроагрегат (205) с гофрированной внутренней поверхностью, который придает гофрированную форму оболочке (104), в то время как по меньшей мере один слой расширяющегося изоляционного материала (118) продолжает расширяться, в результате чего получается изолированная труба в гофрированной оболочке (100), в которой слой расширяющегося изоляционного материала в полностью расширенном состоянии имеет внутренний диаметр dвнут и внешний диаметр dвнеш, который может изменяться от минимального внешнего диаметра dвнеш min до максимального внешнего диаметра dвнеш max, при этом изменение внешнего диаметра обусловлено гофрированной формой оболочки.
2. Способ по п. 1, включающий в себя между этапами b) и с) дополнительный этап, на котором непрерывно пропускают исходный трубный узел (107) в оболочковый экструдер (204) через короткую входную трубу (210), содержащуюся в оболочковом экструдере (204),
3. Способ по любому из пп. 1 или 2, в котором расширяющийся изоляционный материал (102) является термореактивным пенопластом, например, полиуретановым (ПУР) пенопластом, полиизоциануратным (ПИР) пенопластом, полиамидным (ПИ) пенопластом или аналогичным полиизоцианатным пенопластом или другим термореактивным пенопластом, например, эпоксидным пенопластом или фенольным пенопластом.
4. Способ по п. 1, в котором внутренний трубный узел (105) дополнительно содержит один или несколько внутренних слоев изоляционного материала (112), при этом способ дополнительно включает в себя этап, на котором покрывают по меньшей мере одну внутреннюю трубу (101) одним или несколькими внутренними слоями изоляционного материала (112) до выполнения этапа а).
5. Способ по п. 4, в котором один или несколько внутренних слоев изоляционного материала (112) обладают разными характеристиками, например, гибкости, изолирующей способности и/или термоустойчивости, по сравнению с расширяющимся изоляционным материалом.
6. Способ по п. 4, в котором один или несколько внутренних слоев изоляционного материала (112) выбраны из группы, в состав которой входят аэрогели, аэрогельные композиционные материалы, волоконно-армированные аэрогели, минеральная вата или гибкий полиимидный (ПИ) пенопласт.
7. Способ по п. 4, в котором один или несколько внутренних слоев изоляционного материала (112) содержат два, три, четыре, пять, шесть, семь, восемь, девять или десять отдельных внутренних слоев изоляционного материала.
