Abstract
Изобретение относится к производству металлических труб, в частности к производству биметаллических труб, и касается двухслойной металлической трубы и способа ее изготовления. Предложена двухслойная металлическая труба, состоящая из неразъемно механически связанных между собой совместным редуцированием по всей площади цилиндрической поверхности конструкционного слоя и защитного слоя, которые содержат продольные сварные швы, расположенные на различных радиальных лучах поперечного сечения трубы. Предложен также способ изготовления такой двухслойной металлической трубы, в котором электросварные трубы перед редуцированием позиционируют таким образом, что их продольные сварные швы располагают на различных радиальных лучах общего поперечного сечения труб. Труба имеет более низкую стоимость по сравнению с традиционно выпускаемыми двухслойными бесшовными трубами при сравнимых и даже более высоких показателях прочности и долговечности и при более низком расходе материалов.The invention relates to the production of metal pipes, in particular to the production of bimetallic pipes, and relates to a two-layer metal pipe and method of its manufacture. A two-layer metal pipe consisting of mechanically interconnected jointly reducing across the entire area of the cylindrical surface of the structural layer and the protective layer, which contain longitudinal welds located on different radial rays of the pipe cross section, is proposed. A method of manufacturing such a two-layer metal pipe is also proposed, in which electric-welded pipes are positioned before reduction in such a way that their longitudinal welds are placed on different radial rays of the total cross-section of the pipes. The pipe has a lower cost compared to the traditionally produced two-layer seamless pipes with comparable and even higher strength and durability and with a lower consumption of materials.
