In order to ensure the safety of buildings and people, many buildings will be installed fire pipes, but fire pipes can not be installed casually, need to be carried out according to the relevant installation specifications, so what are the requirements of fire pipe installation specifications? Now let's learn with me.

What are the installation specifications for fire pipes?

1, fire pipe thread connection

When reducing the diameter of the fire extinguishing pipe, reduce pipe parts should be used to connect the wire, so as to avoid the use of a replenishment core. If you need to fill the core, then the elbow can not be used up and down, and the three-way parts can only be used 1, the four-way parts can not be more than 2. Threaded sealing packing shall be evenly filled at the threaded position of the pipe. When tightening the thread, do not squeeze the sealing packing into the pipe. After connecting the pipe, clean up the residual sealing packing outside the pipe.

2, fire pipe welding connection

When welding the fire fighting pipe, the difference between the diameter of the reduced pipe can not exceed 50 mm. If it is more than 50 cm, the size of the head should be used for welding, and to ensure that the surface will not appear cracking, porosity, slag, splashing, biting edge, depression or other phenomena.

3, casing

(1) When the fire pipeline is going through the wall, a sleeve should be added when it is going through the floor, and the pipeline weld can not be placed in the sleeve, and the length of the sleeve can not be less than the thickness of the wall.

(2) The floor casing should be 50 mm higher than the floor or ground.

4, fire pipeline installation

(1) No other water facilities should be set up on the pipe behind the alarm valve, and galvanized steel pipe or seamless steel pipe should be used.

(2) When setting up the automatic sprinkler pipe, the slope should be maintained, and the slope should flow to the drainage pipe or auxiliary drainage pipe. The slope of the dry pipe of the wet system should not be less than 0.002°, and the slope of the water distribution pipe and water distribution branch pipe should not be less than 0.005°.

(3) The diameter of all water distribution pipes or water distribution branches shall not be less than 25 mm.

The above is a detailed introduction to the requirements for the installation of fire pipes. I hope it can help you.
