The harm of high building fire is very large. For example, when a fire breaks out in a 100-meter high-rise, the flames and smoke can reach the top floor in about 20-30 seconds. In this special case, the requirements for the fire water pressure is very high, high pressure fire hose came into being, which has super high pressure resistance, can play an important role in dealing with high-rise fire fighting operations.
Fire has a great impact on human society and natural environment. Fire with sudden strong, high destructive, complexity of disasters, disaster accident handling difficult wait for a characteristic, especially the high building fires, often appear the lack of water supply, fire protection channel narrow, fire trucks can’t close to environmental problems, such as fuel at the same time, more people gathered themselves together, and it is to put forward higher requirements for fire extinguishing products.
High pressure polyurethane fire hose is made of polyurethane as the lining of the double hose, high pressure resistance, wear resistance, low elongation, the advantages of moderate inflation, can long-distance conveying water, 2-3 times that of single hose service life. Suitable for all kinds of work place and the environment, in the tall building fire and the application of urban remote water supply play a vital role in the scene.
Compared with the double layer hose, the single layer hose has the characteristics of light weight, small flow resistance, easy winding, easy to use, compared with the single layer hose, the double layer hose is used in worse environment than the single layer, the outer layer of the product is color with dirt resistance, aging resistance, corrosion resistance and easy to distinguish.
