Способ закрепления труб в трубных решетках, при котором на внешней поверхности концов трубы формируют кольцевые выступы, устанавливают ее в решетку, имеющую кольцевые выемки, прямоугольного поперечного сечения, обеспечивая совпадение выступов и выемок, фиксируют трубу от возможного осевого перемещения с последующим ее закреплением в решетке путем приложения осевого сжимающего усилия со стороны внутренней поверхности трубы, отличающийся тем, что на конце трубы формируют внешнее утолщение, например, посредством последовательной высадки с одновременной калибровкой отверстия в трубе на длине утолщения, далее на внешней поверхности утолщения образуют кольцевые выступы трапециевидного поперечного сечения с геометрическими размерами, превышающими требуемые, после чего доводят геометрические размеры кольцевых выступов до требуемых в процессе поверхностного деформирования материала трубы, например, в процессе обкатки калибрами.A method of fixing pipes in tube sheets, in which annular protrusions are formed on the outer surface of the pipe ends, install it in a lattice having ring recesses of rectangular cross-section, ensuring that the protrusions and recesses coincide, fix the pipe from possible axial movement with its subsequent fixing in the grid by application of axial compressive force from the side of the inner surface of the pipe, characterized in that an external thickening is formed at the end of the pipe, for example, by means of successive upsetting and with simultaneous calibration of the hole in the pipe along the length of the thickening, then on the outer surface of the thickening, annular protrusions of a trapezoidal cross section with geometric dimensions exceeding those required are formed, after which the geometric dimensions of the annular protrusions are adjusted to those required during the surface deformation of the pipe material, for example, during the rolling process calibers.
