Method for producing an arrangement according to one of claims 1 to 18, wherein a tubing blank (1a) is glued to the inner wall of a pipe (2), characterised in that the barrier layer (1b) is applied to or introduced into the tubing blank (1a). 20. Method according to claim 19, characterised in that the barrier layer (1b) is applied to the tubing blank (1a) by vacuum deposition. 21. Method according to claim 19, characterised in that the barrier layer (1b) consists of metal and is applied by galvanic means to the tubing blank (1a). 22. Method according to claim 19, characterised in that the tubing blank (1a) is drawn over a tubular sheath (1b) having low gas permeation and forming a barrier layer. 23. Method according to claim 19, characterised in that the tubing blank (1a) is pulled into a tubular sheath having low gas permeation and forming a barrier layer. 24.
