Fire hose is used to transport high-pressure water or foam and other fire-retardant liquid hose. The traditional fire hose with rubber lining, the outer surface of the linen fabric wrapped. Advanced fire hose is made of polyurethane and other polymer materials. Fire hose at both ends of the metal connector, you can connect another hose to extend the distance or connected to the nozzle to increase the liquid injection pressure.
Fire hose is divided into two types of lining and unlined. Lined fire hose, including cotton, nylon lining rubber belt, water-soluble polyester glue, linen coated with plastic water. Unlined water with cotton belt, linen water, ramie water. According to the working pressure is divided into 0.8MPa, 1.0MPa, 1.3MPa, 1.6MPa four categories. According to the diameter is divided into 50,65,80 or 75,90 mm four categories. By weaving way is divided into plain water belt and twill water belt two kinds. The length of each water zone is generally provided for 20 meters.
1. Fire Hose laying should avoid sudden twists and turns, in order to prevent the ability to reduce the water pressure; also avoid reverse to prevent water filled with water after the rotating belt leaving the button with water interface.
2. After filling the water should be forced to avoid drag on the ground, you need to change the position to move up as much as possible to reduce the water belt and the ground wear and tear.
3). Avoid contact with corrosive chemicals such as oils, acids and alkalis.
4. In areas where there may be flame or strong radiant heat, cotton or linen tapes shall be used.
5. After use should be cleaned, unlined water hose to hang the sun, dry coil stored in a cool dry place.
6. The use of process if found to have broken holes, the application of water cloth wrapped tightly, as soon as possible after the darn or viscous fill; when there is obvious damage, it should immediately withdraw from combat readiness.
7. Vehicles need to pass through the laying of the water zone, should be placed in advance through the water retaining bridge.
8. When laying through the railway, should pass under the rail.
9. Lined areas outside the building should be used with a lined with water, so as to avoid freezing water.
