Abstract

Способ производства прямошовных электросварных труб, включающий формовку трубной заготовки в овальный профиль, переформовку овала на круг, нагрев и сварку продольных кромок заготовки и калибровку полученной трубы по наружному диаметру, отличающийся тем, что, с целью компенсации теплового удлинения кромок и повышения стабильности их поперечного и продольного положения в зоне сварки, переформовку овала на круг осуществляют в сварочной клети.The method of production of longitudinal electric welded pipes, including the molding of the pipe billet into an oval profile, reshaping the oval into a circle, heating and welding the longitudinal edges of the billet and calibrating the resulting pipe by the outer diameter, characterized in that, in order to compensate for the thermal elongation of the edges and increase the stability of their transverse and the longitudinal position in the welding zone, the reshaping of the oval on the circle is carried out in the welding cage.
