It undertakes the important task of transporting water to the fire scene and supplying it to fire fighting equipment. It is one of the important equipment to ensure the safety of people's lives and property. Fire hose has special requirements in terms of material, type, installation and maintenance. Common fire hose materials include steel pipes, ribbed cloth pipes, resin pipes and fiberglass pipes. Among them, steel pipes have the characteristics of high strength, corrosion resistance, and wall thickness that can withstand large water pressure, and play an important role in the fire fighting system. ribbed cloth pipes have flexibility, strength and wear resistance, and are suitable for use in fire fighting scenes and building maintenance. Resin pipes and fiberglass pipes have higher corrosion resistance, high temperature resistance, low temperature resistance and explosion resistance, and are widely used in chemical, energy, construction and other fields.
