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 pressuriz

Q:Is the ban on witchcraft in the bible a blanket ban on all magic?
Throw a cloak of invisibility over it after initiating the spin.
Q:simple english help? (i find it confusing)?
I just had the same problem. I replaced the batteries and they chirped louder. I removed the batteries and they continued their chirping. The fact is they are all electronically linked together. So what you have to do is start replacing the smoke detectors until the chirping stops. The problem is defective detectors. I had a repairman come out and do this so I know that this is the problem. I have pets so they were all extremely distressed. One of my dogs is still at the babysitters house recovering. Two of them were so scared that they refused to come back into the house. I had to carry them in (even when the problem was solved they were still scared). They hid for hours until they finally realized there was no more noise and then they came out.
Q:What is the most effective way to remove cat hair from clothing?
Place the hydrant at the origin (0, 0). Then at t 9 sec. the northbound dog is at the point (0, 18). The east bound dog, who passes the hydrant 1 sec. later, is now at the point (27, 0). Rate of change is calculated like slope. (difference of y values)/(difference of x values.) So this becomes (18 - 0)/(0 - 27) which 18/-27 or -2/3. good luck!
Q:do snow tires make a difference?
That was a really exciting finish and a great race overall.
Q:When horses were used to pull the firefighter's.?
Gravity is the curvature of spacetime cause by mass. Light simply follows that curved spacetime, like a train follows the rail tracks.
Q:How much does it cost to move the fire hydrant?
This is not only the problem of disassembly and fire hydrant, but also need to declare the fire inspection and acceptance procedures! Or filing procedures; single disassembly fire hydrant is generally around 600 yuan!
Q:How to do the hydrant water pressure gauge and how much water pressure do the hydrant need?
In the high-pressure, temporary high-pressure fire water supply system, no matter whether the water gun is at the top of any building, the full water column of the water gun should not be less than one 0m.
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:What's the difference between an indoor fire hydrant and an outdoor hydrant?
Outdoor fire water supply pipeline with high pressure, temporary high pressure and low pressure pipelines, towns, residential areas, enterprises and institutions of the outdoor fire water supply, generally uses the low pressure water supply system, often with life and production water supply pipeline with.
Q:Fire control system, the hydrant button directly to start with a few lines, how to pick up?
Four or six lines.
