Pipe deformation process for exhaust pipes involves creating widened and thickened pipe wall directly at end sector

摘要

The deforming process involves applying axial pressure inside a die (3) to the pipe blank (1) and internal pressure to force the blank outwards. The process is used to create a widened and/or thickened pipe wall directly at an end sector (1a) of the blank. The die and the internal pressure are applied specifically to this end sector.
