| description | FIELD: fire-fighting equipment, particularly to supply powder fire-extinguishant for volatile flammable liquid fire suppression, to extinguish fires of energized equipment and service lines, at low temperatures and in northern territories. ^ SUBSTANCE: fire hose comprises air-tight shell and connection heads with central channel. Additional sleeve having lesser diameter is provided inside the air-tight shell. The additional sleeve has wall perforated along hose length and fastened to connection heads provided with coaxial additional channels. The additional channels communicate with cavity defined by inner surface of air-tight shell and with outer surface of additional sleeve. The additional sleeve has outer surface provided with profiled members made as splines and with perforated orifices. The perforated orifices have axes inclined towards powder movement direction. The additional sleeve is provided with stiffening frame made as reinforcing wire. ^ EFFECT: simplified structure, increased technological efficiency of fire hose production and application. ^ 4 cl, 4 dwg |
