FIELD: construction.
SUBSTANCE: invention relates to reinforced hose made of glass fibre. Fire-resistant hose having: nitrile-containing rubber layer of inner tube; two reinforcing layers, at least one insulation layer of rubberised unidirectional cord of fabric of glass fibre, spirally wound at an angle of spiral in range of 40-60 degrees relative to longitudinal axis of hose, and edges of each reinforcing layer are overlapped by a value less or equal to 0.5 inches; optionally rubber damping or jointing layer between reinforcing layers and insulating layers; and polychloroprene rubber outer cover layer. Hose can have one or more spiral wires, embedded in hose, for example, between two reinforcing layers.
EFFECT: technical result is high fire resistance and air-tightness.
