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:I've tried a so many times.
I don't know what my mom has in her car, but it's like..if you lock the car and you're sitting in it, and then you unlock it from the inside, the alarm goes off. It scared the mess out of us. But at least you (and everyone in the county) knows your alarm system works!
Q:cheepest fire extinguisher
Perfect exchange between a couple,..men and football,women and their patient nature Good job. (Come comment on mine pls-)
Q:I have tried every trick in the book and I'm getting close, but she is old enough to have learned. She loves to stay outdoor, but I think she forgets what she out there for and then comes back in and soils. I got that pretty well under control and then she has been messing at night. She and her sister have dry food out all the time and I feed them at 6pm which I figure will give them enough time to process dinner and leave their offerings outside. Any help will be helpful.
maybelline shine-sensational 75 (cherry kiss)its not TOO red but lip gloss doesnt tend to run as deeply colored as lip sticks and stains so maybe ur better off with that instead.
Q:The principle of automatic opening of fire hydrant button
13 years after the implementation of the new police regulations, the fire hydrant alarm button is not directly connected to the pump line, only the signal bus, press the alarm button, the alarm host through the field control module to pump
Q:I have a 24' Sea Ray; I want to mount a fire extinguisher somewhere in the cockpit.
Read the book Baby Bargains. It goes in depth into brands and what to look for. The book was indispensible when setting up my registry and purchasing items. It goes into price range also and there are items considered best within a price range. So for us: carseat- britax stroller - bob clothes - carters and baby gap blanket - swaddle designs diapers - pampers or huggies swing and play mat - fisher price
Q:When changing smoke alarm batteries, why do they all go off while changing?
First get a cell phone video documenting what you see. Report it first to the landlord and tell him you have pictures to prove it. That should take care of it, and if not call the local police non emergency number and ask what to do. In some areas the police take care of this, in others it's Animal Control. In the meantime, a quality pepper spray will make the dog think twice about coming up to you like that. If you have any local Army-Navy or sporting goods stores that deal with hunters those are the best places to get good ones. Many of the cheap ones aren't strong enough. Practice first, aim for the face and eyes of the dog, and use it generously. You can also ask your mail carrier if you see him where he buys his. Most delivery people carry them.
Q:I'm looking for laptop between ?350-450. I realise this isn't enough for a really good gaming laptop. I would like one that has alot of backing storage so i can have all my music on it and be able to run a number of games online and offline. Thanks.
No, the police actually do not have a legal obligation to investigate. They will try to answer all calls for service, but if a shift is busy, they will prioritize calls. A complaint about someone parked in a red zone will go to the bottom of the list.
Q:I have an Acer Aspire 5560G. It burns my legs sometimes, so i put it on a blanket then on top of my legs. It gets really hot and spells like it's burning. Could this cause a fire? :L
If I were him? I'd say I've lost interest in my partner. But this is because of some reason: maybe my partner has changed and she wasn't the woman I met before. Or it could be something else. The thing is, he's won't cheat on you if there was no reason to cheat. However, you have the right to still snoop into his stuff because of what he did and you're just trying to be protective of your relationship. Maybe more communication will settle this out. Best of luck, friend.
Q:what is the working mechanism of this X sting Wish fire-extinguisher ?
Energy equations: E1 (energy when hydrant is at 30m above ground) E2 (energy when it hits the ground) m * g * h 1/2 * m * v^2 the mass is on both sides and will cancel out leaving g * h 1/2 * v^2 9.81 m/s^2 * 30 m 1/2 * v^2 solve for v v 24.26 m/s Let me know if this helps by choosing this as the best answer.
Q:what is the importance of personal presentation in maintaining Health and Safety within the workplace?
do they get pocket money? if they dont then start it and then everytime they do something really bad or do not do something you tell them deduct 10, 20 or 30p put it on a chart to begin with it may not seem like it is working but trust me it will start to when they see something on tv they want, or when the children at school have something that they want ebcause you will not buy it for them they will need to learn to rely on their pocket money more i mean obviously not for essentials like food and water but with things they want liek sweets, toys, etc etc the same goes when they are good, they are able to earn the loast money back if there is no reward there will be no incentive for them to be better! i hope this helps x
