Abstract
Способ закрепления теплообменных труб в отверстиях трубных решеток, включающий выполнение профилированных законцовок на трубах, содержащих бандаж трапециевидного поперечного сечения и калиброванные участки полотна по обеим его сторонам, установку законцовки в трубное отверстие, содержащее главную и вспомогательную кольцевые канавки, располагая бандаж напротив главной кольцевой канавки, фиксацию трубы от возможных перемещений с последующим закреплением законцовки в трубном отверстии путем приложения деформирующего усилия к ее внутренней поверхности, первоначально вызывая свободное заполнение бандажом части объема главной кольцевой канавки с последующим его окончательным закреплением в ней, отличающийся тем, что для образования неразъемных соединений, в условиях превышения механических свойств материала трубы в бандаже механических свойств материала трубной решетки, главную кольцевую канавку выполняют с боковыми стенками в виде конических языков, образуемых верхней и нижней ступенями, перед закреплением законцовку калибруют с приданием внешнему контуру бандажа требуемых геометрических размеров и с образованием на ее внутренней поверхности каверны, и окончательное заполнение бандажом главной кольцевой канавки осуществляют посредством интенсивных разнонаправленных сдвиговых деформаций материала трубной решетки в каждом из упомянутых языков, для чего расстояние между языками главной кольцевой канавки (по ее верхнему и нижнему основаниям) в осевом направлении назначают после замера геометрических размеров бандажа свободно деформированной законцовки до ее конечного внутреннего диаметA method of securing heat transfer pipes in the openings of the tube sheets, including profiled endings on pipes containing a trapezoidal cross-sectional bandage and calibrated sections of the web on both sides thereof, installing the endings in the pipe hole containing the main and auxiliary annular grooves, positioning the bandage opposite the main annular groove, fixing the pipe from possible displacements, followed by fixing the tip in the pipe hole by applying a deforming force to its inside the surface of the surface, initially causing the bandage to freely fill part of the volume of the main annular groove with its subsequent final fixation in it, characterized in that for the formation of one-piece joints, when the mechanical properties of the pipe material in the bandage exceed the mechanical properties of the material of the tube sheet, the main annular groove is made with the side walls in the form of conical tongues formed by the upper and lower steps, before fixing the tip is calibrated to give the external contour b sales of the required geometric dimensions and the formation of a cavity on its inner surface, and the final filling of the main annular groove with the bandage is carried out by means of intensive multidirectional shear deformations of the tube sheet material in each of the mentioned languages, for which the distance between the languages of the main annular groove (along its upper and lower bases ) in the axial direction, after measuring the geometric dimensions of the bandage of the freely deformed ending to its final inner diameter, it is prescribed
