Abstract

Significant metal savings are achieved when using tubular products of variable cross-section in metal structures. Special technical effects are achieved in pipelines with variable medium flow rates. The HPT process with a change in the length of the deformation zone as a result of varying the stroke length of the working stand provides solutions to the following problems. The following features are considered: – shaping of tubular products of variable cross-section; – tool calibration; – determination of the laws of changing the stroke length of the working stand. The issue of improving the mechanisms and components of these machines is considered.
