38 3 FIRE HOSE, NOZZLES, BRASS, & HOSE VALVES Pre-Folded For Pin Racks For emergency use only, FireTech RACK & REEL FIRE HOSE is fully lined, FM approved, and a great value. It has a proof test pressure of 500 psi, service test of 250 psi, and
pressure of 165 psi (11.4 bar or 1138 kPa). II. Service Test Using a Hose Testing Machine. WARNING: Because there is a potential for astrophic failure during the service testing of fire hose, it is
Pressure Restricting Hose Valves. Pressure restricting hose valves are used to restrict the pressure of flowing water up to 175 PSI. They are angle hose valves with preset orifices which restrict the volume of water and thereby lower the pressure of the flowing water. NFPA requires restricting valves where the inlet pressure exceeds 100 PSI.
You have to calculate how many GPM the nozzle is supposed to deliver and at what pressure. Most 1 1/2″ nozzles were 100 GPM at 100 PSI when I was running an engine. Then you have to calculate your friction loss and head pressure and add that to yo
• Elevation Pressure: Pressure that is gained or lost due to elevation (.434 psi rounded up to .5 psi per foot). • Engine: Also known as a “Pumper”. The most basic type of fire apparatus consisting of a fire pump, water tank, and fire hose. • Fire Department
Attack Hose Hose designed to be used to coat fires beyond the incipient stage. Attack hose shall have a minimum design operating test pressure of 275 psi. Attack Hose-1” Booster Line Rubber Hose: Used for Rubbish, Brush, Washdowns Requires High
To fight a fire on the ground, a fire hose needs about 150 pounds per square inch of water pressure. To get water to the 30 th floor of a building, the pressure needs to be about 300 PSI to offset
So that the total pressure drop over the hose length will be 314.5 psi (3.7 x 85). Download Pressure Loss graph (PSI per foot of Hose) > Keep in mind that if you transfer gaseous substance through the hose then you need to find the ratio of the density of gas over the density of water and adjust the pressure drop respectively.

Pressure restricting hose valves are used to restrict the pressure of flowing water up to 175 PSI. They are angle hose valves with preset orifices which restrict the volume of water and thereby lower the pressure of the flowing water. NFPA requires restricting valves where the inlet pressure exceeds 100 PSI. Pin may be removed by firefighters to allow fully open valve. Unlike pressure
Pressure reducing hose valves and floor control valves are used to control the pressure of flowing water in standpipe and sprinkler systems. NFPA requires pressure reducing valves where the inlet pressure exceeds 175 PSI. These pressure reducing valves are of the factory set variety. This means an engineer or contractor would fill out a data sheet to the exact specifiions of what each valve

500 psi Attack Fire Hoses 4 products Attack fire hoses (also known as action fire hoses) convey a stream of water from a fire pump to a fire to stop the fire from spreading and douse the flames. These fireproof hoses are flexible and lightweight so that firefighters
Pressure in a fire hose depends on the type of hose, type of nozzle, and what you’re trying to accomplish with them. An attack line, usually an 1 3/4″ can be used with a solid stream or fog nozzle. A solid stream nozzle requires 50 psi to operate
225 psi Supply Line Fire Hoses 6 products Supply line fire hoses are large-diameter hoses that bring large volumes of water from a hydrant or other pressurized source to a fire pump so it can be conveyed to an attack hose.
