Key Features & Benefits
Common Use and Key Advantages:
common Uses:
Fire pipes are the core supporting pipes for all building and facility fire suppression systems.
- Residential, commercial, and public buildings, covering indoor and outdoor fire hydrant pipelines, automatic sprinkler pipelines, and pipelines supporting fire booster pumps.
- Factory workshops, warehouses, and industrial park supporting buildings, in addition to conventional fire-fighting pipelines, are also used for water supply pipelines for industrial foam fire extinguishing systems and water spray fire extinguishing systems.
advantage Of Fire Pipes：
- High pressure resistance: can meet the high-pressure water supply needs of high-rise buildings without the risk of pipe bursts.
- Corrosion and rust resistant: mostly made with hot-dip galvanizing or internal and external plastic coating processes, making them suitable for long-term use in various humid and chemical environments.
- High temperature resistance and flame retardant: (galvanized, seamless steel) Excellent high temperature resistance, will not easily deform or melt at high temperatures; in addition, the coating is made of flame-retardant material for enhanced safety.
- This pipe is used for sprinkler systems, standpipes, and water lines, offering enhanced corrosion resistance and high-pressure capacity.
