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:Excel VBA Search and Highlight Help; Difference from Majority?
Well, maybe you should ask these several people to pay your ticket, because these several people are severely idiotic, just like you. You can park in front of a fire hydrant, provided you remain in your car and are able to move the vehicle immediately when necessary. But this does not apply to a marked fire lane. Nor does it apply anywhere marked with a red curb. Nor does it apply anywhere marked No Parking. Pay your ticket. Why in the world would you believe that you could park in a zone that is clearly marked no parking - fire lane. And, why would the fact that you live in California make a difference? No parking generally means the same thing in all 50 states, plus the District of Columbia. Seriously, you should actually pay your fine, plus an extra 50% for stupidity.
Q:Making Soaps?
Do you have a hot water bottle? If so, fill it with WARM water (obviously you don't want it really hot), wrap it in a towel and place it by the hedgehogs den, or under the cage (you might have to use books or something to prop the cage so it doesn't wobble). Make sure the hedgehog has another den that's unheated in case it gets too warm. Refilling it 2-3 times a day should be fine. Other options: If you can get to a store that sells 24 hour heat packs before the storm hits that might be your best betpharmacies might have them, also camping supply stores. Lots of pet shops sell microwave heating pads for pets. The two options above can get hot so make sure they are not unbearably hot before you give them to your hedgehog.
Q:Fitting into my clothes better, Please Help!!?
if you do it once or twice, most likely you wont see any ill effects. do it often and you can blow out your struts/shocks. and if you do, from that point forward (until you replace the strut/shock) you will get a 'swimmy' ride whenever you go over bumps. the reason is that the ability of the shock/strut to dampen the imperfections of the road, has been grossly limited. the inside of a shock/strut is just a tube with oil on one end, and a valve with some oil on the other. as you drive, the oil is passed thru the valve. the tighter the valve, the slower the vehicle dip and rise - thereby giving you a firm ride. if that valving becomes damaged, fluid will pass thru much easier. that is what causes the 'swimmy' feeling. and as per the speed suggested for speed bumps (and similar), i slow down til i am nearly stopped, and then slowly continue forward. most people are just in too much of a rush to slow down enough, and dont care about their vehicle's suspension. most people dont understand their suspension, or what a 'well tuned' suspension should feel like.
Q:What are the places that do not set fire hydrant systems?
The fire resistance rating for single or multi Ding, grade one or two and combustible less e factory (warehouse), e building fire resistance rating of three or four and the building volume is not more than 3000m3 class D plant and construction volume of not more than 5000m3 (warehouse), grain warehouse, vault, far from the town and unattended independently the building can not set fire hydrant.
Q:I got an e-mail that says I can get a $1000 Wal Mart gift card?
The Moon orbits the Earth because the Moon has a (near) constant velocity, and because gravity acts as a centripetal force between Earth and the Moon. This force causes the moon to keep going in circles instead of out into space and away from us. If you are asking why gravity works, that is a question of current scientific study (but Einstein's general theory of relativity offers a pretty good guess).
Q:Is there a way to polarize light without losing energy?
The chirping noise may also mean that the sensor is no longer working correctly. If you don't know the age of the detectors, it's probably a good idea to replace ALL of them anyway. The price of smoke detectors is nothing, compared with losing the entire house - or worse. Note that the battery-powered unit probably isn't up to code in your area, so THAT should be the one to go. If there's a house fire, and the insurance company finds that the detectors don't meet code, your coverage may be in question. On the other side of the coin, replacing the existing detectors may -lower- your premium. Things to think about..
Q:Why are fire hydrants equipped with fog nozzles?
The water mist spray gun can also effectively control the concentration of pulverized coal in the air, and can effectively prevent dust explosion. The place where coal is produced and ground is a kind of production place, and it is easy to cause dust explosion when sparks are encountered.
Q:How do fire hydrants work?
Rescue Engine/ Rescue Pumper A Rescue pumper or Rescue engine Is a purpose-built unit of fire apparatus beyond a typical National Fire Protection Association (NFPA) Class A rated engine company. The original concept was to marry the pumping capabilities of a heavy rescue squad and that of a class A rated pumper, that is to add 1000 gpm fire pump or greater and 500 gallons of water. This is a newer concept that first began in the late 1980s early 1990s. This first design did not include all the supply hose that is usually carried on a typical engine company, but had the tool carrying capacity of a heavy squad, including extrication equipment and the specialized rescue tools not carried on ladder trucks or engine companies. The first unit designed by Darley equipment in 1989, for small departments, was never built but other manufacturers (e.g. Pierce), who originally did not want to build a new specialty unit, did finally build one in 1991. Current design: The current design is more like a typical fire engine than a true rescue pumper. Todays Rescue Engine differs from the original unit concept,Rescue Pumper designed by Fire Chief S E Politano, which was simply to add more initial fire fighting (on board water and pumping capacity)capabilities to a heavy rescue squad, not bring heavy rescue squad capabilities to an engine company. Some fire departments that protect a body of water, such as a major city harbor or coastline, may utilise fireboats to combat fires on watercraft and waterfront areas. Such fireboats pump water from under them, so they can theoretically provide water indefinitely. Fire companies may also employ airplanes and helicopters to attack fire from the air. Such aircraft are fitted with large tanks that drop water or fire retardant chemicals onto the fire.

2) The safety hazard, on the contrary, can be greatly reduced if workers wear rubber gloves. I think the rest are right.just change this one. Commas around the prepositional phrase on the contrary.
Q:What kind of hat/cap should I wear to shield my face from the sun?
once the pipe and fittings are clean and sanitary you will need to use the proper solder. most cities require the use of solder that has a ratio of 95/5 mixture of tin. again, you need to check with your local plumbing supply store for the legalities in your city.
