A hydraulic vibration damper has an inner pipe, a center pipe, and an outer pipe. A piston on a piston rod is guided to be displaceable in a working space that is formed by the inner pipe. Flow spaces that are hydraulically separated from one another and connected with a valve module are formed between inner pipe and center pipe. The center pipe has a radially projecting formed-out part, at which the center pipe is connected with the outer pipe or the inner pipe, via a press fit. The passage openings of the center pipe and of the outer pipe are disposed in the region of the formed-out part. Also, a separation system for hydraulic separation of the flow spaces is situated in the region of the formed-out part. Also provided is a method for the production of a three-pipe system for a vibration damper.
