Claims (2)

1. Способ производства передельной трубной заготовки для прокатки холоднокатаных труб большого и среднего диаметров из сплавов на основе титана, включающий производство листовой заготовки, строжку листа по ширине, подготовку кромок листа к сварке, формовку листовой заготовки в трубную заготовку и сварку продольных кромок расходуемым электродом той же марки сплава в защитной среде аргона, отличающийся тем, что передельную трубную заготовку изготавливают формовкой на вальцах с последующей сваркой продольных кромок в защитной среде аргона для прокатки холоднокатаных труб максимального диаметра с последующими перекатами передельных холоднокатаных труб-заготовок в трубы меньшего диаметра.1. Method for the production of a conversion tube billet for rolling cold-rolled large and medium diameter pipes from titanium-based alloys, including the production of a sheet billet, gouging the sheet in width, preparing sheet edges for welding, forming the sheet billet into a tube billet, and welding longitudinal edges with a consumable electrode alloy grades in the argon protective medium, characterized in that the conversion tube billet is made by molding on rollers with subsequent welding of the longitudinal edges in the protective argon medium for rolling cold-rolled pipes of maximum diameter with subsequent rolling of the converted cold-rolled tubes-blanks into pipes of a smaller diameter. 2. Способ по п.1, отличающийся тем, что передельную трубную заготовку прокатывают в холоднокатаную трубу максимального диаметра с отношением D/S=30-40, которую при последующих перекатах прокатывают в трубы меньшего диаметра с увеличением отношения D/S от 2 до 20 за каждый перекат, а последний перекат производят с отношением D/S=80-100.2. The method according to claim 1, characterized in that the conversion pipe billet is rolled into a cold-rolled pipe of maximum diameter with a ratio of D / S = 30-40, which during subsequent rolling is rolled into pipes of smaller diameter with an increase in the D / S ratio from 2 to 20 for each roll, and the last roll is performed with the ratio D / S = 80-100.
