1. Multi-storey building fire pipe network setting
a. When there are more than 10 indoor fire hydrants and the fire water consumption exceeds 15L/s, the indoor fire water supply pipeline should have at least two water inlet pipes connected to the outdoor pipe network, and the indoor pipes should be looped or the water inlet pipe should be connected to the outdoor pipe in a ring shape.
b. The indoor fire standpipes of high-rise industrial buildings should be annular, and the diameter of the pipes should not be less than 100mm.
c. For workshops and warehouses with more than four floors, high-rise industrial buildings, residences with fire pipe networks, and other civil facilities with more than five stories, the fire water supply pipes should be equipped with water pump adapters.
2. High-rise building fire pipe network setting
a. There are independent fire-fighting water supply systems and regional centralized fire-fighting water supply systems.
b. According to the height of the building, there are partitioned and non-partitioned fire-fighting water supply systems.
c. Introduce pipe ≮ 2, ring network.
d. The fire water supply pipeline should be equipped with a water pump adapter.
e. The fire standpipe shall ensure that the water guns of two adjacent fire hydrants on the same floor fill the water column and reach any part of the room at the same time. The diameter of the riser is not less than 100mm.
f. Use a single outlet bolt, the water tank is ≮7m away from the bolt, otherwise pressurize and start the pump from a long distance, and the pump must be created 5 minutes after the fire alarm.
g. Set up separately or independently from the automatic spraying system before the alarm valve.
