Abstract

Способ производства прямошовных электросварных труб, включающий формовку трубной заготовки и сварку ее кромок, отличающийся тем, что, с целью увеличения скорости сварки и повышения качества сварного соединения при изготовлении труб из высоколегированных и коррозионно-стойких сталей и сплавов, на участке кристаллизации шва за пределами околошовной зоны создают перепад температур в пределах 50 - 150C по толщине стенки трубы с возрастанием температуры от внутренней поверхности трубы к наружной.Method for the production of longitudinal welded pipes, including the molding of the billet and the welding of its edges, characterized in that, in order to increase the welding speed and improve the quality of the welded joint in the manufacture of pipes from high-alloyed and corrosion-resistant steels and alloys, at the site of solidification of the weld outside heat-resistant the zones create temperature differences in the range of 50–150 ° C over the thickness of the pipe wall with increasing temperature from the inside surface of the pipe to the outside.
