Abstract
The method involves shaping a pipe from a metallic material into a high pressure-resistant metal bellow (1) by an internal pressure shaping process. A material with two meta-stable material conditions is utilized in the form of the metallic material. The two conditions are ductile material condition and high-strength material condition with increased yield strength. The shaping of the pipe into the metal bellow is performed in the ductile material condition, and the material of the metal bellow is transferred into a high-strength material condition after the shaping process.
