The reinforced flexible hose comprises (a) An inner lining consisting of a cylindrical metallic tube impervious to the effluents being transported. (b) An armoured layer (3) which resists internal and external pressure. (c) An impervious extruded plastics casing (4,6). There is an intermediate plastics layer (2) between the lining tube and the armoured pressure resistant layer. The intermediate layer is extruded continuously onto the tube or is wound onto the tube. An armoured layer (5) which is resistant to traction is placed outside the pressure-resistant layer, outside. The first impervious casing and inside the second impervious casing. There is a flexible metallic protective layer, consisting of e.g. chain mail. The armoured pressure-resistant layer is made of an interlocking metal spiral of S-section. |
