Abstract
The pipe for the transport of warm or hot fluids comprises an inner tubing (1) forming the transport pipe, an external protective tubing (4) and a heat insulating layer (3) disposed in between. The internal tubing (1) is made of a synthetic material armed with glass fibers and is surrounded by a metallic sheet (2) acting as a vapor screen since the synthetic material is vapor-permeable. In order to avoid the formation of water pockets, the metallic sheet (2) is applied onto the inner tubing (1) without forming air pockets. When the inner tubing is formed of epoxyde resin, a rotational moulding is particularly appropriate whereby the wall of the mould is lined with the metallic sheet (2) for obtaining the inner tube of a part, the metallic sheet forming a construction unit. If the inner tubing (1) is made of a vinylic polyester the metallic sheet may be wound helically around the inner tubing by applying a tension or by pressing it against the tubing in order to prevent the formation of air pockets. To link neighbouring tubes a sleeve (6) of synthetic material is glued onto the naked end of the inner tubing (1) which is also provided with a metallic sheet (2) and comprises a wedge-shaped zone (10) into which the naked end of the neighbouring tubing is inserted and secured by means of a synthetic glue (11). Because the vapor diffusion takes place nearly only in a radial direction, the axial slot between the metallic sheets (2, 2a) does not have any negative influence on the vapor screen in the joining zone, especially if the metallic sheet comprises an axial overlap.
