However it is a multipurpose hose also commonly used within the shipboard and marine industry, on refineries and construction sites, in agriculture and irrigation, general industrial use and for all wash-down applications.
What size is a typical fire hose?
The standard three sizes of hose lines are 1½, 1¾ and 2½ inch. Depending on the size and severity of the fire, hose line requirements vary to get the job done efficiently. Selecting the incorrect one from the start can cause delays in fire suppression and exhaustion.
How much pressure is in a fire hose?
The usual working pressure of a firehose can vary between 8 and 20 bar (800 and 2,000 kPa; 116 and 290 psi) while per the NFPA 1961 Fire Hose Standard, its bursting pressure is in excess of 110 bar. (11,000kPa; 1600psi) Hose is one of the basic, essential pieces of fire-fighting equipment.
What is a Playpipe nozzle?
The underwriter’s playpipe is a straight-stream nozzle that discharges water streams over long distances. Playpipes feature a remarkably smooth, long pipe—often 30 inches or so—that straightens a stream of water while reducing turbulence. Firefighters originally used playpipes as outdoor hose nozzles.
What are fire fighting nozzles?
Fire nozzles can provide a constant flow or allow firefighters to select the most appropriate flow rate and operating pressure for fire fighting. A fire nozzle connects to a fire hose to deliver water or fire fighting foam to extinguish a fire.
How do I know what size fire hose I have?
The general rule that most firefighters can remember is small fire equals small water and big fire equals big water. Small water refers to your basic 1½- or 1¾-inch hoselines; the big water refers to the 2½-inch hoseline. With a 1½-inch nozzle, the average water delivery rate can be between 150 to 200 gpm.
What size hose gives more pressure?
Method 2: Using a shorter and bigger hose to increase the output pressure. If you want to increase the water pressure from a hose, you can decrease the length and increase the size. Water that flows through a hose will have resistance. A 3/4″ hose will see a decrease of around 2 PSI per 100 ft.
How do you measure a hose diameter?
How does a fire hose nozzle work?
The pressure-control spring senses any increase or decrease in pressure within the nozzle. It then moves the baffle in or out to maintain a particular tip size necessary to keep the nozzle pressure at 100 psi. In effect, the nozzle is constantly changing tip size to match the water being supplied at that moment.
How far can a fire hose shoot water?
Between 75 feet and 100 feet straight up, depending on water pressure. In practice, though, firefighters on the ground rarely attempt to reach higher than 40 feet with hoses.
How do you use a fire hose nozzle?

What is nozzle size?
Nozzles are manufactured specifically for each machine’s volume and pressure. This means that each nozzle size has a different size orifice (or opening). There are a variety of sizes but the most commonly used are between 3.0 to 6.5, sized in . 5 increments.

Why are fire hoses different colors?
The colors indicate the rated water-flow capacity of that particular hydrant: Red indicates a water-flow capacity of fewer than 500 gallons per minute (GPM). Orange indicates a water-flow capacity of 500 to 999 GPM. Green indicates a water-flow capacity of 1,000 to 1,499 GPM.
What is a Class 1 standpipe?

What size hose fits a fire hydrant?
The 1905 NFPA Standard specified that fire hydrants have 2.5 inch-hose connection nozzles with 7.5 threads per inch, and 4.5 inch-engine suction (or pumper) connection nozzles with 4 threads per inch [5]. These specifications remain as the current standard for fire hydrants.
