FIELD: machine building.SUBSTANCE: lining hose for coating application comprises a reinforcing shell 1 and a thermoplastic shell 2. The shell 1 is made of at least one layer of fibrous and/or woven material by joining the longitudinal sides of the said material web with its further impregnation by a thermosetting binder. The shell 2 is inseparably connected to the outer surface of the reinforcing shell along its whole circumference. The layer of the reinforcing shell 1 connected to the thermoplastic shell 2 is fitted by a fibreglass reinforcing layer 3, and the radial distance T1 between the fibreglass reinforcing layer 3 and the thermoplastic shell 2 is less than the radial distance R1 between the fibreglass reinforcing layer and the inner surface of this layer of the reinforcing shell 1.EFFECT: improved quality of the applied coating, lower buckling and stretching of a thermoplastic shell and the lining hose reinforcing shell layer connected to it in the course of coating application.11 cl, 3 dwg |
