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:When I'm driving and hit a little bump my car feels like it's going to get out of control? ?
When I was near one, I just stared at it, it was tempting me.
Q:Born before 1980? How many of you can remember this?
I once had the same thing happen and found it to be small bugs that were living in the toasty warm detector. They were apparently were crawling in the photo sensor or making small webs, partially blocking the photo cell and tricking the detector and setting it off. I was thumping on the detector one time when it went off. A small bug fell out - that's how I figured it out. Once I got the bugs out and cleaned out the webs, it stopped.
Q:Can you tell me the fire hydrant and fire extinguisher are the same thing?
The outdoor fire hydrant is divided into two kinds according to its installation form. The fire hydrant installed on the ground is called ground hydrant, which is suitable for the areas with higher temperature. The fire hydrant installed below the ground is called underground fire hydrant, which is suitable for cold areas.
Q:How is the enriched water column defined by a fire hydrant?
Building water supply and drainage, wrote: "water guns in the diameter of 26~38cm round section, containing all the water 75%~90% dense water column length, called the full length of the water column.". The length of the water column ranges from 7 to 15 meters (including 7 and 15 meters). Less than 7 meters, difficult to approach the fire source, greater than 15 meters, recoil force is too large. Fire water writes: "enriched water column" means the amount of water from the nozzle to the dense jet, 90% of which passes through a dense jet at the diameter of 38cm. "Fire code for building design" GB50016-2014 pointed out that: water jet from the water jet nozzle, 90% of the water column through the diameter of 380mm round hole at the length of a jet.

Q:what matches do you see at wrestlemania next year?
Ahhhh, no. But they sure look funny when they hit those electric lines. ;)
Q:What do you think about the song &If God Will Send His Angels& by U2?
Don't know of any alternative solders. But if you have some experience with 'sweating pipes', while the joint is still fluid, do a quick wipe around the joint with a rag to remove the excess solder. This leaves a very narrow, clean and consistent looking silver solder line around the joint. Conscientious plumbers always do this - or they have just the right touch to only load the joint with just enough solder to fill the joint and nothing more. Alternatively, spray paint the plumbing to match whatever you like.
