Among various types of firefighting equipment, fire hoses may seem ordinary, but they are an indispensable "lifeline" in firefighting operations. It is a flexible hose used to deliver high-pressure water and foam extinguishing agent. One end is connected to a fire hydrant, fire pump or water source, and the other end is connected to a water gun to send the extinguishing agent to the fire location. It is the core equipment for initial fire fighting and firemen's close combat fire fighting.
The fire hose is mainly composed of three parts: inner lining, woven outer layer, and metal interface. Common rubber lining PVC、 Made of polyurethane material, ensuring a sealed and non permeable environment; The outer layer is mostly woven with polyester filament, which is wear-resistant and tensile resistant; Both ends are equipped with metal fire interfaces, which facilitate quick docking and extend the water supply distance. According to the national standard GB 6246, fire hoses are divided into Class I and Class II. Class I is used for firefighting and rescue teams to tackle fires, with higher performance requirements; Class II is commonly used in building fire hydrant cabinets for daily storage and low-frequency use.
We often see model labels such as 10-65-25, where 10 represents a design working pressure of 1.0MPa, 65 represents a nominal inner diameter of 65mm, and 25 represents a length of 25 meters. The mainstream diameters on the market are 50mm, 65mm, and 80mm, with conventional lengths of 15m, 20m, and 25m, suitable for different scenarios such as building fire hydrants, fire truck water supply, and forest firefighting. A qualified fire hose must obtain CCC compulsory certification, and its pressure resistance, wear resistance and anti-aging indicators must meet the standards. Poor quality water hoses are prone to bursting and leaking when filled with water, which can directly delay fire extinguishing at critical moments. When selecting and inspecting, it is necessary to check the verification certificate and identification information.
Water and fire are ruthless, and this soft water hose carries the heavy responsibility of protecting life and property. Understanding fire hoses and their purpose is the first lesson in fire safety.
