Product Description:

We make different styles of indoor hydrant, landing hydrant, underground hydrant,etc.

1. Item: SNJ 65

2. Type:SN50,SN65

3. Strength test pressure:2.4mpa

4. The indoor fire hydrant is a fixed indoor fire-fighting equipment in factories, public buildings, warehouse,etc.


Indoor fire hydrant is the connecter in the water piping network, including one valve with single outlet, One Valve with double outlet and double valve with double outlet etc. It's used to offer assistance to control the fire.

Rated working pressure:16 Bar

Strength test pressure:24Bar



A hose is attached to the fire hydrant, then the valve is opened to provide a powerful flow of water, on the order of 350 kPa (50 lbf/in²) (this pressure varies according to region and depends on various factors including the size and location of the attached water main). This hose can be further attached to a fire engine, which can then use a powerful pump to boost the water pressure and possibly split it into multiple streams. The hose may be connected with a threaded connection, instantaneous "quick" connector or a Storz connector. Care should be taken not to open or close a fire hydrant too quickly, as this can create a water hammer which can damage nearby pipes and equipment. The water inside a charged hoseline causes it to be very heavy and high water pressure causes it to be stiff and unable to make a tight turn while pressurized.

Q:Can water fire hydrant be installed in the electric switch room?
Generally do not need, electrical equipment fire, certainly can not use water to destroy ah.According to the requirements of the fire design, adopts the gas quenching tank or fire extinguisher.
Q:Is there any hidden danger of fire hydrant?
Fire hydrant is not safe, it is certain that when there is a fire, the fire hydrant does not have a gun head or a water hose. What's more, there is no water in the fire hydrant, and it will kill people! Therefore, these fire facilities should be checked regularly, to eliminate hidden dangers, to ensure the integrity of fire fighting facilities and to ensure safe production.
Q:Will the water from the fire hydrant be stolen? Can you run out of water? And consequences?
Fire and water pipelines will be the same, because each month the water, for every household in the table and the table of increasing building balance of doubt, and find you.
Q:Can fire hydrant decoration be packed with material?
That's ok! But you have to leave a door and put a fire hydrant on the door, so the firemen won't say what's wrong with you! And it's not against the law. That's what you're allowed to do!
Q:Fire hydrant can not drink water?

Q:What's the fire hydrant interface?
You ask is not detailed, I guess you might ask is the three interface size of the outdoor fire hydrant above is not the same, the reasons are as follows: the most common outdoor fire hydrant ground hydrant has three interfaces, two 65MM diameter, a 100MM diameter, 65MM diameter corresponding to the water interface, usually a bayonet 100MM, the corresponding caliber fire truck water pipe, usually thread, to explain the end.
Q:Maintenance requirements for outdoor fire hydrants
In order to facilitate fighting, but also in order to fire pool from the threat of building fire, fire pool intake or water wells from the location of the building, generally less than 5m, preferably not more than 40m. But considering the design of regional or centralized high pressure (or temporary high pressure) water supply system, it is difficult to do so. Therefore, this article stipulates that the distance between fire water intake and protected buildings should not exceed 100m.
Q:Fire hydrant has been on the water, fire pump can start?
If there is a constant pressure pump and the flow of the stabilizing pump is less than the flow of the hydrant, the fire pump can be started when the pressure of the pipe network is reduced and the starting pump pressure is reached. Of course, if there is a day pool, or constant pressure pump flow can supply fire hydrant discharge flow, it will not start the large pump.
Q:How often is the indoor hydrant checked?
The water storage capacity of fire water source should be enough, found insufficient, added in time, and changed water according to local environment and condition.
Q:How many fire hydrants can the fire hydrant supervisor take with a diameter of 100?
Hydrants, officially called fire hydrants, are a type of fixed fire fighting facilities, which control fuel, insulate fire and eliminate fire. Indoor fire hydrant and outdoor hydrant. The fire fighting system includes outdoor fire hydrant system, indoor fire hydrant system, fire extinguisher system, and some automatic sprinkler system, water gun system, gas fire extinguishing system, fire detection system, water mist system and so on.
