Claims (1)

Способ изготовления двухстенных сварных труб на трубоэлектросварочном агрегате, включающий установку на трубе меньшего диаметра центрирующих элементов и концентричное размещение трубы меньшего диаметра внутри трубы большего диаметра с образованием зазора между трубами, отличающийся тем, что трубу меньшего диаметра подают в формуемую трубу большего диаметра со скоростью формовки-сварки последней, причем на трубе меньшего диаметра перед этим закрепляют центрирующие элементы, обеспечивающие образование сообщающихся протяженных полостей в межтрубном пространстве, затем производят сварку кромок сформованной трубы большего диаметра и ее калибровку, при этом по меньшей мере процессы закрепления центрирующих элементов, сварки и калибровки трубы выполняют в технологическом потоке агрегата.A method of manufacturing a double-walled welded pipe on a pipe-welding unit, comprising installing centering elements on a pipe of a smaller diameter and concentric placement of a pipe of a smaller diameter inside a pipe of a larger diameter with the formation of a gap between the pipes, characterized in that the pipe of a smaller diameter is fed into a pipe of larger diameter with a forming speed of welding of the latter, and on the pipe of a smaller diameter before this, centering elements are fixed, which ensure the formation of interconnected extended floors stey in the annulus, and then welding the edges of the molded produce pipe of larger diameter and its calibration, wherein at least fixing processes centering elements, welding and calibration tube is performed in the process stream unit.
