Abstract: In the present article the process of a tube shell producing from TiNi shape memory alloy rods and subsequent plugging are described. The deformation-temperature conditions of a shell plugging from an outer diameter of 38 to 26 mm and a tube schedule form 10 mm to 3.3 mm on a floating mandrel is considered in detail. The design features of the rolling mill and the tools used are analyzed. TiNi SMA seamless tubes with various outer diameters and pipes schedule were produced. During the production cycle mechanical and functional properties of SMA pipes are stable and are comparable with properties of initial SMA rods. Suggested technological scheme of TiNi seamless tubes productionn is promising in terms of the low metal consumption, simplicity of applied technological processes and tubes price reduction. The reported study was funded by the Russian Science Foundation (project no.23-19-00729, https://rscf.ru/project/23-19-00729/).
