CA-FIRE Indoor Fire Hydrant With Aluminum Russian-Style Coupling

This Indoor Fire Hydrant With Aluminum Russian-Style Coupling is a core terminal device for building indoor fire water supply systems, featuring a ductile iron main body and an aluminum Russian-style quick-connect coupling. Compliant with Chinese standard GB 3445-2018 Indoor Fire Hydrants and Russian GOST 12.2.003-74 (for coupling compatibility), it is engineered for rapid fire suppression response.

Fire Safety Knowledge Integration: As specified in GB 50974-2014 Code for Design of Fire Water Supply and Hydrant Systems, indoor fire hydrants are critical for initial fire extinguishment-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 suppress Class A solid fires like wood or fabric blazes).

3.1 Ductile Iron Main Body (Fire-Resilient Design)

Made of QT450-10 ductile iron (tensile strength ≥450MPa), the main body withstands high-pressure water impact during emergency use-meeting the high-load requirements of fire systems. Its red epoxy powder coating passes 1000h neutral salt spray tests, resisting corrosion in humid indoor environments (e.g., basement fire cabinets) for ≥10 years.

3.2 Aluminum Russian-Style Coupling (Emergency-Optimized)

The lightweight aluminum coupling is 40% lighter than cast iron alternatives, enabling fast one-person operation. Its Russian-style quick-connect structure allows secure water hose docking in ≤10 seconds (critical for initial fire response), while the integrated silicone rubber seal ring maintains leak-free performance under 1.6MPa pressure (compatible with -40~80℃ temperature fluctuations).

3.3 Fire-Compliant Human-Machine Design

The corrugated anti-slip handwheel is sized for gloved fire-fighter operation, ensuring smooth valve opening/closing even in high-stress scenarios. The hydrant's compact structure fits standard fire cabinets (650×450×240mm), complying with space requirements for indoor fire facility layout.

Application Scenarios & Fire Safety Compliance

This hydrant is suitable for indoor fire water supply systems in:

Office buildings, commercial complexes, and high-rise residential lobbies (aligned with GB 50974-2018 layout standards).

Industrial workshops and warehouses (especially projects adopting Russian fire equipment specifications).

Basements and underground parking lots (corrosion-resistant coating adapts to humid environments).

Key Fire Safety Note: Per fire codes, each hydrant must be unobstructed (no storage or decorations blocking the 1.5m front operating space) to ensure immediate access during emergencies.

5. Installation & Maintenance (Fire Code-Aligned)

5.1 Installation Requirements

Mount at 1.1m above ground level (per GB 50974-2014), with ≥0.5m side clearance and ≥1.5m front clearance for operation.

Connect the lower port to DN50 fire water piping; match the aluminum coupling with Russian-standard Φ65 fire hoses.

After installation, conduct pressure tests (2.4MPa strength + 1.76MPa seal) to verify performance.

5.2 Maintenance Protocol (Fire Safety Mandates)

Monthly Inspection (Mandatory): Check handwheel flexibility, coupling seal integrity, and ensure no obstructions (per local fire department regulations).

Annual Pressure Test: Re-test at 2.4MPa (strength) and 1.76MPa (seal) for 2 minutes-replace the hydrant if leakage occurs.

3-Year Seal Replacement: Swap the coupling's silicone seal ring to prevent aging-induced leaks (critical for emergency reliability).

1. What is the material of the French-type coupling?
It is manufactured from high-quality brass, ensuring excellent corrosion resistance, durability, and reliable performance in harsh firefighting environments.

2. What hose sizes are compatible with this coupling?
French-type couplings are available in multiple sizes such as 1", 1.5", and 2". Custom dimensions can be provided to match your hose specifications.

3. Is the coupling compatible with other international standards?
French-type couplings follow specific French standards, but adapters can be supplied for compatibility with BSP, NST, Storz, and other fittings.

4. Can the coupling be used for both water and foam systems?
Yes, the brass material and sealing design make it suitable for water supply, foam systems, and general fire-fighting operations.

5. Do you offer OEM/ODM customization?
Yes, logo engraving, customized threads, size options, and special packaging can all be provided according to customer requirements.
