Products with varying cross-sectional height are used in various hydraulic pipelines [1-4]. These products are very easy to manufacture. However, when it comes to hydraulic pipelines of fuel systems, it is essential to use materials resistant to aggressive effects, which are rather difficult to handle [5-8]. In this case, one of the possible options for obtaining such products is hot forming, namely crimping. In view of this, the article considers the crimping of shells made of titanium 6Al-4V alloy. Various combinations of technological parameters and their influence on the flow of metal and the geometry of products are considered. Rational deformation-rate conditions of deformation are found.
