The difference between fire hose reel and fire hose

Fire reel is called “fire hose reel”, which is composed of the valve, input pipe, hose, gun, etc., and can spray fire extinguishing agent in the process of quickly unfolding the hose.

A fire hose is used to transport high-pressure water or foam and another fire-retardant liquid hose. The traditional fire hose is lined with rubber and wrapped with linen woven fabric on the outer surface. Advanced fire hoses are made of polymeric materials such as polyurethane. Both ends of the fire hose have metal connectors, which can be connected to another hose to extend the distance or connected to a nozzle to increase the pressure of the liquid spray.

The difference between fire hose reels and fire hoses is that

A. fire hose is mainly used in fire fighting, when the fire occurs in the fire truck can not reach the height or building interior by the firefighters connected to the fire hydrant to use the fire.

Second, the fire hose reel is mainly for small fires, the use of simple methods, water flow is smaller.

Specifications are different.

Fire hose reel and fire hose role is the fire hose reel pipe diameter DN25, easy to use mainly for the initial fire. Fire hose diameter DN65, two people need to operate, mainly for the medium-term fire.

Different materials.

The fire reel uses a rubber hose. The traditional fire hose is lined with rubber and wrapped with linen woven fabric on the outer surface. Advanced fire hoses are made of polymeric materials such as polyurethane.

Setting Requirements

Fire reel：

Fire hose reels or light fire hoses should be set in densely populated public buildings, buildings with a building height greater than l00m, and commercial service outlets with a floor area greater than 200m2. High-rise residential buildings should be equipped with light fire hoses. High-rise residential buildings should be equipped with light fire hoses.

High-grade hotels, important office buildings, a class of commercial buildings, exhibition buildings, comprehensive buildings, and other high-rise buildings with a building height of more than 100m should be equipped with fire reels, and their water consumption may not be counted in the total amount of water for fire fighting. The spacing of the fire reel should ensure that a water flow can reach any part of the indoor ground, and the installation height of the fire reel should be easy to access, and the action is flexible without a card block. The diameter of the spigot of the fire reel should be 25mm; the inner diameter of the tape is not less than 19mm; the caliber of the nozzle of the fire reel is not less than 6.00mm.

Fire hydrant：

The following buildings or places should have indoor fire hydrant systems.

1. plants and warehouses with a building footprint greater than 300m2.
2. high-rise public buildings and residential buildings with a building height greater than 21m.

Note: The building height is not greater than 27m residential buildings, set indoor fire hydrant system is really difficult, can only set dry fire hose and DN65 indoor fire hydrant without fire hydrant box.

3. Volume is greater than 5000m3 of stations, terminals, airports waiting for trains (ships, aircraft) buildings, exhibition buildings, store buildings, hotel buildings, medical buildings and library buildings, and other single, multi-story buildings.
4. Premium, first-class theaters, theaters, and cinemas of other grades with more than 800 seats and auditoriums with more than 1200 seats, gymnasiums, and other single- and multi-story buildings.
5. Building height greater than 15m or volume greater than 10000m3 of office buildings, teaching buildings, and other single, multi-story civil buildings.
