SPRINKLER - LUCKY NUMBERS (PART I)
Every construction project has a fire protection system, always with the presence of SPRINKLER – THAT IS THE SOUL OF FIRE FIGHTING. THowever, we really understood, grasped and implemented it well!? Always looking forward to contributing a little effort in sacred mission that God has given - fire protection industry. DONATECH, I would like to inform you, friends near and far about the standards for the SPRINKLER system in fire protection work. Looking forward to receiving suggestions, and feedback from brothers from all over the world. Dear.
STANDARDS FOR SPRINKLER SYSTEM:
Depending on the air temperature in the room, the SPRINKLER water spray and fire extinguishing foam need to be designed to suit rooms with the lowest air temperature of the year above 4 degrees Celsius.
Each fire fighting cluster is only arrangedmax 800 SPRINKLER spray water or foam, and the total capacity of the SPRINKLER assembly lines to spray foam should not exceed 2 000 liters.There is no limit to the capacity of pipes located in the sprinkler system.
In buildings with ceiling beams (roof) made of non-combustible materials and combustible materials with protrusions over 0.2m and ceilings (roof) made of incombustible materials with overhangs higher than 0.32m, SPRINKLERs are arranged between trusses and other building structures.
Distance between fire sprinklers and ceiling (roof) plane Not larger than 0.4m, and not less than 0.08m. The distance between the underside of the foam nozzle of the foam fire suppression system to the ceiling (roof) plane should not be more than 0.5m.
In the rooms where SPRINKLER will be installed, there are working floors and ventilation boxes of round or square section with a larger diameter or side size: 0.75m then start required to install additional SPRINKLERs under these floors or vents.
The distance between the SPRINKLER and flammable walls should not exceed 1.2m.
In buildings with one or two pitched roofs with a slope greater than 1/3, horizontal distance from SPRINKLER to wall and from SPRINKLER to edge of roof must not exceed 0.8m for flammable and difficult-to-burn roofs and not exceed 1.5m for non-flammable roofs.
Where there is a risk of the SPRINKLER being subjected to mechanical forces causing damage, then adequate safeguards must be in place.
The impact temperature of the SPRINKLER of the system SPRINKLER Fire fighting with water is regulated as follows:
TEMPERATURE MAXIMUM AIR IN THE ROOM
TO:
|
SELECTSPRINKLER
|
55°
|
68° hoặc 72°
|
56°C – 70°C

|
71°C – 100°C
|
141°C
|
101°C – 140°C
|

The detailed volumetric foam firefighting should only be designed for the rooms in which volume due to foam does not exceed: 3000m³.
