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:What are the forms and scope of indoor fire hydrant systems?
Automatic sprinkler system: used for large and high-rise public buildings, fires, dangerous buildings and national important buildings.
Q:What is this kind of furniture surface called?
It is possible the smoke alarm had been hard wired. I live in an apartment complex and the maintenance folks recently changed the detectors to be hard wired. Hard wired connects to the same wire the lights do. Once hard wired no batteries are needed. If batteries are still needed the outer cover should easily just twist off. If not one or two screws need to be unscrewed. Do not force anything. good luck
Q:What Will Happen to my Cat if I'm Gone for a Year?
if there both traveling the same exact speed in the same direction, they cant possibly collide. if the rear one was going 85.1 and the other was going 85.0, then it would be a .1 km/h impact speed. having rearended a friend that softly, i can state positively he didnt even notice it. until i floored the throttle and his slow POS started going faster.. (dont do this, not smart, not safe. no matter how much fun it was)
Q:Is the hand button the same as the hydrant button?
Normally, when the fire alarm button is reported manually, the probability of fire is much larger than that of the fire detector, and there is almost no possibility of false alarm. Because the manual fire alarm button alarm, the starting condition is to manually press the button to start.
