Abstract
In a pipe line for an engine, in particular a cooling line in aircraft construction, the walls of the pipe line are composed of a load-bearing inner layer (2) of fibre reinforced, curable synthetic resin and of a heat insulating outer layer (3) of fibre reinforced curable synthetic resin, bonded to the inner layer (2). For the production of the two layers (2, 3) a removable core (1) is used, for example composed of a low melting metal alloy.
