Способ производства холоднокатаных труб большого и среднего диаметров из сплавов на основе титана из сварных заготовок с одним или двумя продольными швами, включающий формовку листовых заготовок на вальцах в трубные передельные заготовки или формовку полуцилиндров, сварку продольных кромок расходуемым или не расходуемым электродом в защитной среде аргона с усилением наружных швов 1,0-1,5 мм, а внутренних не более 1,0 мм и прокатку их в холоднокатаные трубы максимального диаметра, отличающийся тем, что перед прокаткой передельных заготовок в товарные трубы максимального диаметра производят технологический прокат их в передельные трубные заготовки с обжатием сварных швов 20-25%.
A method for the production of cold-rolled large and medium diameter pipes from titanium-based alloys from welded billets with one or two longitudinal seams, comprising forming sheet billets on rollers into pipe billets or forming half cylinders, welding longitudinal edges with a consumable or non-consumable electrode in an argon protective environment with reinforcement of the external joints 1.0-1.5 mm, and internal no more than 1.0 mm and rolling them into cold-rolled pipes of maximum diameter, characterized in that before rolling the billets technological tubes are rolled into commodity pipes of the maximum diameter into conversion pipe billets with compression of welds of 20-25%.
