CA-FIRE Indoor Copper Fire Hydrant

Fire Safety Basics Integration: Per Code for Fire Protection Design of Buildings (GB 50016-2014, 2018 revision), indoor fire hydrants are the primary tool for initial fire suppression-they must be accessible within 30 seconds of a fire alarm, paired with a 25m Φ65 fire hose and 19mm water gun to deliver a minimum flow rate of 5L/s (sufficient to control Class A solid fires, e.g., wood, fabric, or paper blazes, in their early stages).

1 High-Performance Material Engineering

HPb58-3 Brass Body: Outperforms standard H62 brass with higher lead content (58% copper, 3% lead), enhancing machinability and ensuring thread precision for NPT interface tightness. It passes 1200h neutral salt spray tests, resisting corrosion in coastal or high-humidity buildings (e.g., underground malls with frequent water vapor).

SUS304 Valve Stem: Prevents rust-induced jamming-critical for cold regions (-20℃) where frozen water often causes valve seizure in ordinary steel stems. The stem is pre-lubricated with food-grade silicone grease during assembly to maintain smooth lifting/lowering without additional maintenance for 12 months.

Nitrile Rubber Seals: Withstands 80℃ high-temperature water (common in fire systems using heated water sources) and resists swelling from fire-fighting foam, ensuring seal integrity for ≥5 years.

2 Fire-Response Optimized Design

Right-Angle Compact Structure: Fits standard 650×450×240mm fire cabinets, complying with GB 50974-2014's "no protrusion beyond cabinet edges" requirement-avoiding accidental collision damage in crowded corridors.

Anti-Slip Handwheel: Features a red corrugated surface (high-visibility for smoke-filled environments) and ergonomic diameter (120mm) for single-hand operation, enabling fast valve opening even with wet, gloved hands.

Dual-Stage Pressure Resistance: The valve body undergoes integral casting to eliminate internal pores, passing 2.4MPa strength tests (1.5× nominal pressure) to withstand water hammer during sudden system activation-preventing burst failures in high-pressure fire networks.

1 Installation Requirements (Per GB 50974-2014)

Mounting Height: Fix at 1.1m above finished floor (tolerance ±5mm) to ensure operability for adults of average height; avoid mounting near heat sources (e.g., air vents) to prevent seal aging.

Clearance Rules: Reserve a 1.5m×1.0m unobstructed area in front of the hydrant-blocking this space (e.g., with cleaning carts) violates fire codes and may result in administrative penalties.

Thread Connection: Use PTFE tape (avoid hemp) for NPT interface sealing; tighten the inlet thread to 10~12N·m to prevent leakage-over-tightening will damage the brass thread.

Post-Installation Testing: Conduct seal and strength tests within 24 hours of installation; record test data in the fire facility maintenance log (required for annual fire inspections).

2 Maintenance Protocol (Fire Department Guidelines)

Monthly Visual Inspection: Check handwheel rotation smoothness, thread integrity, and red paint visibility (touch up with fire-rated red paint if chipped to ensure emergency identification).

Quarterly Silicone Grease Check: Inspect the valve stem for grease residue; replenish with food-grade silicone grease if dry (ordinary grease will corrode nitrile rubber seals).

Annual Pressure Retest: Re-perform 1.6MPa seal and 2.4MPa strength tests; replace the hydrant if leakage occurs at the valve stem or thread interface.

3-Year Seal Replacement: Swap nitrile rubber seals and aluminum gaskets-even without visible damage, aging seals may cause hidden leakage under high pressure.
