The fire hose is a pipe used to transmit water, mainly used for fire fighting and rescue in fire fighting work. Fire hoses are generally made of materials such as rubber and plastic, and different types of fire hoses can be selected according to specific needs and occasions.
Different types of fire hoses are mainly divided into the following categories:
1. Rubber fire hose: NR or SBR rubber is commonly used as the material; it is usually used for fire extinguishing of large fires, with good pressure resistance and folding resistance, and has certain wear resistance.
2. Combined fire hose: It is composed of multi-layer materials, including anti-folding layer, glue layer and support layer. It has good anti-folding performance, light structure, and is easy to carry and store.
3. PVC fire hose: made of PVC material, light, easy to carry, non-flammable and good oil resistance, while the internal fiber is reinforced, high pressure resistance.
The main function of the fire hose is to transport the water used for fire extinguishing, which can lead the water flow into the burning area of the fire source, so as to achieve the purpose of extinguishing the fire. At the same time, in the rescue scene, the fire hose can also be used to achieve some special rescue methods, such as hanging.
