Abstract
The invention relates to a method for producing a pressure vessel (1) for storing gaseous fuels, in particular for a motor vehicle, comprising the steps of providing a support tube (2), providing a blocking tube (3) which has an outer diameter (31) which is smaller than an inner diameter (22) of the support tube (2), arranging the blocking tube (3) inside the support tube (2), and deforming the support tube (2) in such a way that an inner surface (22a) of the support tube (2) rests against an outer surface (31a) of the blocking tube (3), in order to produce a double tube (4).

Method for producing a pressure vessel for storing gaseous fuels for a motor vehicle, comprising the steps of:
- providing a support tube, providing a blocking tube which has an outer diameter which is smaller than an inner diameter of the support tube,
- arranging the blocking tube inside the support tube,
- deforming the support tube in such a way that an inner surface of the support tube rests against an outer surface of the blocking tube, in order to produce a double tube, and
- separating the double tube into several double tube pieces to produce several pressure vessels.
