What is the pressure of fire hydrant in roof test?

When installing a fire hydrant, be sure to know its pressure. Only when you know the pressure can you use it correctly. Next, I will introduce the pressure of fire hydrants in the roof test.

What is the pressure of fire hydrant in roof test?

Should not be greater than 0.50MPa, greater than 0.70MPa, to reset the pressure relief device, to ensure the height of the hydraulic column. Because the fire hydrant system is at the end and is not equipped with a water testing device, fire hydrants are installed on the roof to test the pressure of the pipe network, and the pressure value needs to be above 5 kg to be qualified.

What are the requirements for installing fire hydrants?

1, when installing a fire hydrant, when the location requirement is relatively high, the location requirement is also relatively high, which is also an obvious location, and the fire hydrant should be placed in this location, which is relatively easy to get, otherwise it will be difficult to meet the setting standards of fire hydrants.

2. If it is a fire hydrant installed in a cold storage, then the location of the fire hydrant should be designed in the stairwell or at a normal temperature, so that the fire hydrant will have some influence because the temperature is too low.

3. Fire hydrants can be installed in a relatively large area. This is to set a corresponding number according to the design drawings, and the interval between fire hydrants should also be within the standard range, so as to pass the acceptance.

4. If it is a flat roof, when installing fire hydrants, it is also necessary to set fire hydrants specially used for testing or inspection, so as to facilitate the maintenance and overhaul at the back.

5. When installing fire hydrants, it is also required to check the distance between the bottom and the ground. Generally speaking, it can be controlled between 12 and 22 cm.

Summary: The pressure of fire hydrant in roof test is so much that it cannot be lower than 0.50MPa. When it exceeds 0.70MPa, the pressure relief device should be reset and the height of hydraulic column should be ensured. I hope the above introduction can bring you some help.
