FIELD: mechanics; hydraulics. ^ SUBSTANCE: invention relates to designs of rubber-textile products, in particular, to flexible armoured high-pressure hoses and is designed to be used in ship pipelines. The flexible armoured hose incorporating a flange, a bead ring/bead rings, rubber sealing and surface layers, armouring cord layers has its flange made with a cylindrical bulge whereon located circumferentially are the teeth in the form of one or several rows of combs with a cavity for the sealing rubber layer to be inserted thereto, while the flange area accommodates the rubberised cord bands cut at an angle of 0°. The invention allows increasing the strength of the carcass, the strength of coupling between the rubberised cord and the flange body in operation, tightness of the hose, hence. increasing the operating reliability of the hydraulic system of pipelines. ^ EFFECT: increasing the operating reliability of the hydraulic system of pipelines. ^ 2 cl, 2 dwg |
