Multiple-Outlet Pressure-Resistant Pillar Fire Hydrant

(Large-Diameter Multi-Branch Water Supply Hub for Large-Scale Outdoor Fire Rescue)

 

1. Product Name & Positioning

 

Full Name: CA-Fire FPH-4 Series Multiple-Outlet Pressure-Resistant Pillar Fire Hydrant (DI/Brass Material, DN200~DN300 Nominal Diameter, DN65/DN80/DN100 Multi-Outlet, 1.6MPa Working Pressure, CCC/ISO Certified)

Abbreviation: CA-Fire FPH-4 Multi-Outlet Pressure-Resistant Hydrant

Core Positioning: A high-capacity, multi-branch outdoor fire water supply terminal-distinct from previous medium-small caliber 消火栓 (e.g., SN65 indoor,3-way above-ground) and focused on large-scale fire scenarios. It features an ultra-large nominal diameter (DN200~DN300),multiple interchangeable outlets and 6-pillar pressure-resistant base, designed exclusively for large open areas (e.g., industrial parks,ports,airport tarmacs) where massive water flow and multi-directional supply are required. With DI/brass durability,1.6MPa pressure resistance and flexible outlet combinations, it fills the gap of "large-flow + multi-branch + high stability" in outdoor fire supply-becoming a core component for large-area fire suppression.

 

2. Core Product Advantages

 

1. Ultra-Large Nominal Diameter (DN200~DN300): Support Massive Water Flow

Unlike medium-small caliber hydrants (DN100~DN150), this model's large-diameter design prioritizes high-volume supply:

DN200~DN300 nominal diameter enables maximum flow up to 150L/s-3x that of DN150 hydrants (50L/s). For a 10,000㎡ industrial park fire, 1 DN300 model can cover the entire area with water in 20 minutes, vs. 3+ medium-caliber hydrants.

Optimized internal flow channel with streamlined structure, pressure loss <0.07MPa at maximum flow (1.6MPa working pressure)-ensuring stable water pressure for long-distance fire hoses (e.g., 150m 100mm hoses still maintain 1.3MPa pressure).

2. 6-Pillar Pressure-Resistant Base: Super Stability for Outdoor Use

A key design for high-intensity scenarios, unmatched by ordinary hydrants' 3-4 pillar bases:

The bottom is equipped with 6 reinforced DI pillars (tensile strength ≥450MPa) that anchor to the ground via expansion bolts. It can withstand 12kN lateral impact (e.g., from fire trucks or heavy equipment) without tilting or cracking-ordinary hydrants often fail under 8kN impact.

Integrated pillar body with one-piece casting, avoiding leakage from assembled joints (a common issue with split-type large-diameter hydrants) and ensuring structural stability in harsh outdoor environments.

3. Multi-Outlet Flexibility (DN65/DN80/DN100): Adapt to Diverse Hose Sizes

Offers interchangeable outlet options to match different fire-fighting needs:

Main outlet (DN100): Connects to large-diameter industrial hoses for massive water supply (e.g., fire truck main hoses).

Auxiliary outlets (DN65/DN80): Pair with medium-small hoses for on-site team operations (e.g., handheld foam nozzles,portable water cannons).This "1 main + multiple auxiliary" combination enables simultaneous large-scale water delivery and precision rescue-solving the "single-outlet bottleneck" of ordinary large-diameter hydrants.

4. DI/Brass Material Combination: Durability for Harsh Outdoor Conditions

Body (DI): Ductile iron (QT450-10) with double anti-corrosion treatment (inner epoxy coating + outer polyurethane paint), passing 600-hour salt spray tests-resists industrial dust,salt fog (coastal areas) and chemical vapors (chemical parks).

Key components (Brass): Outlets,valve cores and seals use H59-1 brass, offering better wear resistance and corrosion resistance than steel components. The brass valve core can withstand 10,000+ on-off operations without leakage-extending service life to 25-30 years.

5. CCC/ISO Dual Certification: Compliance with Global Standards

Certified by both CCC (China Compulsory Certification for Fire Products) and ISO 9001, ensuring compliance with fire safety regulations in major export markets (Colombia,Malaysia,Argentina . This eliminates certification barriers for international projects, a critical advantage over non-certified large-diameter hydrants.

4. Applicable Scenarios

 

Large Industrial Parks: Petrochemical bases,automotive manufacturing plants-DN300 model supplies massive water/foam mixture for large liquid or solid fires.

Ports & Airports: Container ports,airport tarmacs-multi-outlet design supports simultaneous rescue by multiple fire teams, covering cargo yards or aircraft parking areas.

Urban Large-Scale Venues: Stadiums,exhibition centers-large flow meets rapid fire suppression needs for crowded public spaces.

Highway Service Areas & Logistics Hubs: Large truck parking lots,cargo warehouses-DN200 model balances flow and cost, covering 8000~15000㎡ areas with minimal hydrant quantity.

 

5. Frequently Asked Questions (FAQ)

 

Will using multiple outlets at the same time reduce water pressure?No. The internal flow channel is designed for balanced pressure distribution-when all outlets are in use, each maintains ≥1.2MPa working pressure (meets standard fire hose requirements). The 1.6MPa rated pressure ensures no significant pressure drop even with multi-branch supply.

How to choose the nominal diameter (DN200 vs. DN300)?

DN200: Suitable for medium-large scenarios (e.g., 5000~10000㎡ industrial workshops) with flow demand ≤100L/s.

DN300: For large-scale areas (e.g., ≥10000㎡ ports,airport tarmacs) needing flow up to 150L/s. Consult our technical team for customized sizing based on your site area and fire risk level.

What's the installation requirement for the 6-pillar base?The base requires a concrete foundation (size ≥1200×1200×800mm) to ensure anchoring stability. The hydrant should be installed ≥5m away from buildings or flammable materials, with the outlet 1.2~1.5m above ground for easy hose connection.

What's the difference between DI and brass components?

DI (ductile iron) body: Provides structural strength and pressure resistance, suitable for outdoor harsh environments.

Brass components (outlets,valve cores): Offer corrosion resistance and tight sealing, avoiding leakage and wear from frequent use. The combination balances strength and sealing performance.
