Beschreibung
Zusammenfassung:	protection of inner surface of pipelines. SUBSTANCE: hose includes arranged concentrically outer hose film envelope, reinforcing envelope and inner hose film envelope. Reinforcing envelope has at side of inner envelope thermoplast layer rigidly joined with reinforcing envelope and being inner surface of said envelope. Lateral edges of envelope together with lateral edges of thermoplast layer are mutually connected. Inner hose three-layer film envelope has mutually joined first outer layer including as thermoplast polymeric material polyamide adjoining to inner surface of reinforcing envelope and capable to be separated from said envelope; second intermediate layer being in contact with outer layer and including as thermoplast polymeric material polyamide or polyamide based polymeric adhesive; and third inner layer being in contact with intermediate layer and including as thermoplast polymeric material mixture of polyethylene and polypropylene. EFFECT: enhanced quality of lining. 4 cl, 3 dwg
