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

 s


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:In Einstein’s theory regarding the existence of gravitation, how does he describe space? What causes the attraction between space bodies?my subject is earth science.
You can have a security system in your house without a phone line, but if you want the system to notify a security company when there is an intruder etc then I believe you do need a phone line or possibly at least an internet connection. I'm not aware of any that work with cell phones and if you are out with your cell phone anyway, the system would never be able to use the phone to make the call.
Q:My cat behaves pretty strangely when playing with objects made of rubber or other squishy stretchy rubber like material. I don’t buy her toys like this, but sometimes she finds an elastic band, or an eraser, or squishy toys made of that weird hyperflex material. Once she does, they hold her interest for a long time, and she meows in a very strange way. In my opinion, it sounds like s sad meow, and she keeps meowing at me and trying to get my attention.I’m just wondering if the material is harmful in anyway? Why does my cat react so strangely around those objects? From her meows she sounds upset, but she keeps playing with them and seems to be having a blast.
What's worse is that in order for them to have the warning, someone would have had to have done that. Wow. That's just a shame. LOL So yes ignorant. Much like on a blow-dryer. Do not dry hair while in shower. 'Cause if it didn't say that LOL
Q:The main fire hydrant in the basement is connected to the municipal water supply pipe directly. Is there a fire pump and a fire pool?
If there is only a basement and the municipal water supply can meet the demand of water and water requirements for indoor and outdoor water as planned, the pump pool can be cancelled. Remember, you must have two pipes.
Q:I just need to know the army regulation for this. thanks!!!
Conviction-free and accident-free are two totally different things. If you weren't convicted of anything, you're still conviction free. You'd know if you were convicted, because you would have been issued a ticket and been found / pled guilty. Backing into a hydrant is an at fault accident. But if you weren't charged with anything, you can't be convicted.

Q:I've just watched a simulation that shows how gravity works. A heavy ball representing the sun is placed on a spread sheet. The sheet bends from the weight of the ball. The earth is represented by another smaller ball that rotates around the concave created by the heavier ball.But this simulation assumes that the universe is a flat plane. If the universe exists in 4D then each planet/sun must be falling or being pushed from another energy source.to create a bend in the universe.There's no gravity force for billions of miles to affect our sun, so how is its force determined?

You can't legally park in front of a fire hydrant.
Q:how can i disconnect the smoke detector temporarily?? coz whenever i bake beef using the oven, it will beep and it's annoying. thanks!
I would think that he could still be a firefighter. There are all different jobs pertaining to firefighters. The step man is the one that is right there putting out the fire. Then you have search and rescue men. I would think he could do the job of truckie, which hooks up the hoses to the trucks, and fire hydrants, and turns on the hydrants. I would say that you would need to contact your local department cheif, and check with what the department policy is. If its a paid department, and they won't allow him to do so, I'm sure that there is a volunteer department somewhere close that will.
Q:Method for using indoor fire hydrant
How to use fire hydrants1, open the fire hydrant door, press the internal fire alarm button (button is to alarm and start fire pump).2, a person connected to the gun head and hose to the fire point.3. The other man connects the hose and the valve door.4, turn the valve counterclockwise, water can be ejected. Note: electric fire should be determined to cut off the power supply.
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!
