摘要： The invention relates to a tubing arrangement for lining pipes, to a method for producing the same and to a method for lining pipes. The invention especially relates to superpressure pipes with an internal working pressure of greater than 16 bar. In order to prevent the pipe tubing from being damaged in the case of accidents or when the pipes are placed out of service, the tubing (1) has a barrier layer (1b) which has a gas permeation of less than 1 ml/(bar d m2) for nonpolar gases and of less than 0.1 ml/(bar d m2) for polar gases. Preferably, the gas permeation ranges from 0.0001 ml/(bar d m2) to 0.01 ml/(bar d m2).
