Description

Technical Field

[0001] The present application relates to the technical field of fire protection pipes, and in particular to a fixing device for fire protection pipes in underground pipe galleries. Background Art

[0002] Fire protection pipes refer to piping systems specifically used for fire protection purposes, which are used to transport water for fire fighting. Fire protection pipes are usually made of corrosion-resistant metal materials, such as steel (black iron, galvanized steel pipes), stainless steel, etc., to ensure the durability and stability of the system for long-term use. Fire protection pipes are usually arranged through walls, floors and ceilings to protect the pipes from damage or destruction, ensuring reliable water supply in emergency situations. Fire protection pipe systems use special connectors and valves to ensure that water flow can be quickly started and shut down when necessary, as well as to drain and maintain the pipes. Fire protection pipe systems need to be inspected and maintained regularly to ensure the integrity and performance of pipes, valves and connectors, as well as the normal operation of water flow and stable pressure. Fire protection pipe systems are one of the most critical safety facilities in buildings. Their design, installation and maintenance are essential to the fire fighting effect and the safety of buildings.
