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.

The utility model is used for supplying water to a fire engine or directly connected with a water hose and a water gun, and is a necessary fire extinguishing water supply facility outdoors. It shows the upper part of the ground, the sign is obvious, easy to use. It is composed of valve body, elbow, seat, valve, drain valve, valve stem and interface. Fire hydrant on the ground is a necessary fire fighting equipment in the city, especially in the urban areas and less rivers. It is necessary to install the fire hydrant to ensure the fire water supply. Factories and mines, warehouses, docks, freight yards, high-rise buildings, public places and other densely populated areas should be installed.
Q:What does "fire hydrant SS100/65" mean?
SS100 indicates outdoor fire hydrant, inlet diameter 100mm, outlet quick interface is 65.Path defined: a conic (in addition to a circle), over the focus and perpendicular to the axis of the string.
Q:Is there any hidden danger of fire hydrant?
(1) the disposition and establishment of fire control facilities, equipment or fire safety signs do not conform to the state standards or industry standards, or have not been kept in good condition and effective;From the management point of view, I do not know the fire facilities are bad, or know that the bad, not repaired, indicating that there is a problem managementSo this is definitely hidden trouble
Q:Are hydrants, feed pumps, and fire pumps alike?
Fire pump is only used in the fire, usually by the high level fire water tank and booster pressure regulating pump to maintain system pressure, that is temporary high voltage system.
Q:Has the hydrant been discharged from the main engine?
The main fire engine hits the automatic state, and the fire control cabinet hits the automatic state.
Q:What kind of fire can not be used on the ground hydrant, please heroes to answer, thank you.
ComputerWhen the computer is on fire, unplug the power immediately and use dry powder or carbon dioxide extinguisher to save it. If found in a timely manner, you can also unplug the power, quickly wet carpet or quilt and so on to cover the computer, do not splash water on the fire. Because of the sudden drop in temperature, the computer exploded.
Q:The fire engine always fails to report: does the fire hydrant button report model not conform to the problem?
Very simple, the equipment alone in the host (loop, called the fault should be removed) if it continues to change, it is basically normal weight code because a check it slowly.Another reason is that because the host doesn't match the device, it's basically impossible. The old machine (dial code switch) can't afford new equipment (electronic coding)
Q:Excuse me, indoor fire hydrant. Thank you. How long is the water column length required?
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. Fire hydrant mainly for fire engines from the municipal water supply network or outdoor fire water network to implement fire fighting, can also be directly connected to the hose, water gun fire extinguishing. Therefore, indoor and outdoor fire hydrant system is also one of the important fire fighting facilities.
Q:Proper connection of fire hose with indoor hydrant and water gun
Use of fire hose. When using the fire hose, the high pressure hose should be placed close to the water pump. The water hose after the water filling should be prevented from twisting or bending suddenly, and the collision of the water hose interface shall be prevented
