Using ordinary black pipes for fire-fighting systems in an attempt to reduce procurement costs can lead to failure in final acceptance testing and create potential safety hazards.
Fire protection pipe networks are kept closed and circulated with water for a long time, and are most susceptible to rust, scale buildup, and blockage. Ordinary black pipes are prone to oxidation and rust. Rust flakes off and accumulates on the pipe walls. With long-term use, the inner diameter of the pipe decreases, the nozzles become clogged, and the valves become stuck. In the event of a fire, the water output and water pressure are insufficient, which directly affects the effectiveness of fire rescue and poses a great safety hazard. The zinc coating on the galvanized pipe protects the pipe wall, making it less prone to rust and scaling, ensuring clean water quality, and guaranteeing smooth water flow and stable operation of the fire protection system.
Galvanized pipes are corrosion-resistant, moisture-resistant, and suitable for complex building environments. Fire protection pipes are often embedded in ceilings, shafts, and damp underground areas, which are dark and damp all year round. Ordinary black pipes will corrode extensively within a few months, resulting in a very short service life and making later maintenance and replacement extremely difficult. Hot-dip galvanized pipes have strong anti-corrosion properties, are resistant to moisture, oxidation, and aging, and will not rust even after years of use. They are suitable for long-term concealed construction conditions, requiring no maintenance and minimal repairs.
