A fire hydrant is a visible connection point that is placed at a defined location to supply water. From Building to any industrial area, it must have a Fire Hydrant System. In this article, I am gonna show you the complete information on Fire Hydrant systems.
So, Let’s dive right now.
What is Fire Hydrant System?
Fire fighting hydrant systems are the most widely used system in many residential and industrial projects. If you’ve ever seen a “red” colored pipe, revolving around a building or factory, you’ve seen a fire hydrant pipe. All buildings, parking areas, roadsides, mines, industrial areas, etc. must have a fire hydrant with a connection to a water service network. In the Fire Hydrant System point, it is placed a defined location for tapping firefighters into the water supply.
Fire Hydrant System is designed to provide firefighters with the water they need immediately to fight and extinguish fires. However, since the 19th century, overhead column-type fire hydrants have become popular and are mostly used. A fire hydrant is basically a pipe with a valve control through which water flows from the head of the water to extinguish the fire.
What is the Purpose and Uses of Fire Hydrant?
Supplying the water to extinguish the fire is the main and primary purpose of a fire hydrant to fight against the fire. Though, a Fire Hydrant system can be used for many types of purposes such as:
- System Testing: Fire Hydrant system can be used to test the hydraulic pressure and capacity of the distribution system.
- Line Flushing: Due to its high flow capacity and easy operation, fire hydrants can be used to flush main distribution system lines.
- Other use cases: Fire hydrants are often used as a source of water for commercial construction work, sewer cleaning, road construction, road cleaning, etc.
How do Fire Hydrant Systems Function?
Fire Hydrant System is specially called “Fire Well”. In this system, water was stored in the Hydrant system throughout the year. This water well is connected to the pump room. From the pump room, there are two to three main pipes.
These pipes form a network of pipes that cover the factory compound and the factory. The pump has a job, constantly filling all the pipes connected to the water under pressure. The pressure of the system is around 7 to 10 times. When a person sees a fire, they activate the hydrant system and point to the fire. A very strong current of water now attacks the fire and eventually the fire is extinguished. By maintaining the pressure of the system, the pump constantly pumps the water pressure and supply.
What are the Types of Fire Hydrant systems?
Basically, there are 2 types of Fire Hydrant systems available in the market;
1. Dry Fire Hydrant
2. Wet Fire Hydrant
1. Dry Fire hydrant
A dry hydrant system stores water underground. The temperature of the earth is usually higher than the temperature of the cold environment of the cold region. When a dry hydrant system needs to be used, firefighters open a valve on top of the hydrant and attach their hose to it. This opens the drain valve inside the hydrant. This allows water to come through which firefighters use against the fire.
- Dry Fire hydrant systems are used in cold regions where routine water temperature drops below freezing temperatures.
- In addition, The maintenance of the Dry Fire Hydrants system is very difficult.
- The design of the dry barrel is kept under the ground to avoid water accumulation.
- Dry barrels or Dry wet hydrants are also expensive and difficult to build.
2. Wet Fire hydrant
Wet hydrant Systems are widely used in places where freezing is not a problem. In the Wet fire hydrant system, the main water supplies the hydrant closer to the surface. Thus, in cold weather, it is susceptible to freezing.
- Basically, Wet Hydrant system, water is stored above the ground.
- Wet hydrants are used where water accumulation is not a problem.
- Wet hydrants are easy to make and inexpensive.
- It is very easy to access and maintain the Wet Hydrants System.
What are the advantages and Disadvantages of Fire Hydrant Systems?
Advantage:
To extinguish the fire in open areas Fire hydrant systems are very powerful and effective. It has a long range. Since the fire hydrant system is spread out, fire hydrants can attack the fire from different angles.
- This is very easy to operate the full process, due to its stable installation. You don’t worry about the installation service, Arnavindia: Fire hydrant system supplier is always open their service for you.
- The ring of the Fire Hydrants in the building is placed under the ground, so there are no barriers for vehicles, and are not affected by the fire.
- From the availability of water and pressure at the beginning of the fire to the main fire it is the most useful system for controlling and extinguishing.
- Other systems such as water spray, sprinkler, and foam systems can be tapped from this system.
Disadvantage:
- You need to manually activate the System in any normal ad or very emergency case.
- As, because the pressure and flow of the fire hydrant system are very high. two people are required to hold the pipe.
- Fire can damage hydrant systems, instruments, or machines.
Conclusion
To sum up, the Fire Hydrant system works very effectively in open area fire. the Flow of the water is very high. Therefore, I hope you have got the complete information on this Fire Hydrant System Designing from this article.
