Three-layer hose suction o specific the structure intended for discharge very hot (up to 1100°C) gases, vapours, fumes and air. outer Layer impregnated fabric glass with threads of steel stainless ensures strength mechanical, central thick fabric high-temperature fully role insulating, inner very fine mesh of steel stainless separates flow hot gases. Flame-retardant, to some extent resistant to hot sparks. used at furnaces and engines for extraction gases o very high temperature, in industry metallurgical, ceramic, shipbuilding, aviation, automotive and equipment military. hose o strong the structure and resistance to impacts thanks to outer spiral. Used only as a suction hose working under vacuum, due to the possibility of gases penetrating outwards under overpressure (degassing). hoses o small diameter internal < 100 mm are characterized tzw. two-hose design (Layer inner with mesh constitutes separate hose of spiral). Assembly of the hose on connectors with bridge clamps (lewo-handed). length standard: od 2 for 10 m - depending on the diameter. Hose material: 3 layer: externally impregnated fabric glass with fibres of steel stainless (grey), central Layer - high-temperature fabric insulating, inside fine mesh - steel stainless. Reinforcement: outer spiral with wire and sheet of steel stainless. Operating temperature: od -50°C up to +1100°C.
