Abstract
Способ гибки тонкостенных труб с наполнителем, содержащим воду, которые охлаждают до температуры заморозки наполнителя, и затем деформируют трубогибочным устройством, отличающийся тем, что в наполнитель вводят растворимую в воде соль, при этом ее концентрацию выбирают такой, чтобы после заморозки наполнителя, его физико-механические параметры обеспечивали ему необходимые прочностные характеристики, а температуру заморозки выбирают в зависимости от солености наполнителя такой, чтобы коэффициент объемного расширения наполнителя был равен нулю.A method of bending thin-walled pipes with a filler containing water, which is cooled to a freezing temperature of the filler, and then deformed with a pipe bending device, characterized in that a salt soluble in water is introduced into the filler, and its concentration is chosen such that after freezing the filler, its physical mechanical parameters provided him with the necessary strength characteristics, and the freezing temperature is chosen depending on the salinity of the filler so that the volume expansion coefficient of the filler is p aven to zero.
