A hose for lining pressure pipe lines is described, comprising a web being made up of warp and woof threads, which are made of plastic, as well as a coating of thermoplastic material, which coating is impermeable to the medium to be transported in said pipe lines and is applied onto one side of said web. Due to the pressure of a fluid, the hose is introduced into a pipe line and turned up therewith, in which case a cement in the interior of said hose will, prior to turning-up, come between the outside of said hose and the inside wall of said pipe line. In order to, on the one hand, obtain high strength in longitudinal direction and to, on the other hand, facilitate introduction of said hose into said pipe line, the stretching ability of said web, in transverse direction of said hose, is greater by at least one third, as compared to that in its longitudinal direction, and preferably at least twice as great. In said web, the proportion of said warp threads, advantageously, is > 65 percent by weight and the proportion of said woof threads, advantageously is < 35 percent by weight. Furthermore, the warp threads may be smooth and the woof threads may be slightly textured. Preferably, a type of web is chosen, with which incorporation for said warp threads will be <2 percent and for said woof threads will be > 12 percent.
