CA-Fire Outdoor Grounding Pillar-Type Fire Hydrants

(Large-Flow Column-Structured Water Supply Terminal for Large-Scale Outdoor Fire Rescue)

 

1. Product Name & Positioning

 

Full Name: CA-Fire CCC & ISO Certified Outdoor Grounding Pillar-Type Fire Hydrants (DI/Brass Material, DN200~DN300 Nominal Diameter, Large-Flow Design)

Abbreviation: CA-Fire Pillar-Type Outdoor Fire Hydrant

Core Positioning: A large-flow, column-structured outdoor fire water supply terminal-fundamentally different from our previous underground hydrants (concealed installation),3-way above-ground hydrants (multi-branch focus) and small-caliber above-ground hydrants (low flow). It features a sturdy pillar-type body and ultra-large nominal diameter (DN200~DN300) to deliver high-volume water flow, designed exclusively for large-scale fire scenarios (e.g., industrial parks,airport tarmacs) where small-caliber hydrants lack water supply capacity. With DI/brass durability,1.6MPa pressure resistance and multi-outlet flexibility, it fills the gap of "large-flow + stable grounding" in outdoor fire supply systems-becoming a core component for large-area fire suppression.

 

2. Core Product Advantages

 

1. Ultra-Large Caliber & Large-Flow Design: Meet Large-Scale Fire Needs

Unlike small-caliber hydrants (DN100~DN150, flow ≤50L/s), this pillar-type hydrant focuses on high-volume water supply:

Nominal diameter DN200~DN300: The main inlet/outlet adopts ultra-large caliber (DN200 for medium-scale, DN300 for large-scale), supporting maximum flow up to 120L/s-2.4x that of DN150 hydrants (50L/s). For a 5000㎡ factory fire, 1 DN300 model can cover the entire area with water in 15 minutes, vs. 3 DN150 hydrants (45 minutes total).

Optimized internal flow channel: The cavity is designed with a streamlined structure (no right-angle bends) to minimize pressure loss-when flowing at 100L/s, pressure loss is <0.08MPa (1.6MPa working pressure), 33% lower than small-caliber hydrants (≤0.12MPa). This ensures sufficient pressure for long-distance fire hoses (e.g., 100m 100mm hoses still maintain 1.2MPa pressure).

2. Pillar-Type Grounding Structure: Super Stability for Outdoor Use

A key difference from portable or semi-grounded hydrants-this product uses a fixed pillar-type design:

6-pillar pressure-resistant base: The bottom is equipped with 6 reinforced support pillars (DI material, tensile strength ≥450MPa) that anchor to the ground via expansion bolts. The structure can withstand 10kN lateral impact (e.g., from fire trucks) without tilting-small-caliber hydrants (3-pillar base) often lean or topple under 5kN impact.

Integrated pillar body: The above-ground pillar (height 1.8~2.2m, customizable) is made of one-piece DI casting, avoiding leakage from assembled joints (a common issue with split-type above-ground hydrants). The smooth outer surface is easy to clean, even in dusty industrial areas.

3. DI/Brass Material Combination: Durability for Harsh Outdoor Environments

Main body (DI): Ductile iron (QT450-10) with double anti-corrosion treatment (inner epoxy coating + outer polyurethane paint) resists industrial dust,chemical vapors (e.g., near chemical plants) and salt spray (coastal areas). Passes 700-hour salt spray tests-service life extends to 25~30 years (small-caliber cast iron hydrants last 10~15 years).

Key components (Brass): Outlets,valve cores and seals use H59-1 brass, which has better wear resistance and corrosion resistance than ordinary steel components. The brass valve core can withstand 10,000+ on/off operations without leakage-5x more durable than steel cores (2,000 operations).

4. Multi-Outlet Flexibility: Adapt to Different Fire Hoses

Unlike single-outlet large-caliber hydrants, this model offers multiple outlet options to match various hose sizes:

Main outlet: DN200/DN300 flange connection (for large-diameter industrial hoses, e.g., 200mm fire hoses for fire trucks).

Auxiliary outlets: 2~3 DN65/DN80/DN100 ports (threaded/flange) for small-to-medium hoses (e.g., 65mm handheld nozzles for on-site teams). This "1 main + multiple auxiliary" design enables simultaneous large-scale water supply and local precision rescue-small-caliber hydrants lack such flexibility.

5. Cost-Effective for Large Areas: Reduce Hydrant Quantity & Installation Cost

For large-scale sites, the large-flow design cuts overall investment:

Fewer units needed: A 10,000㎡ logistics park only requires 2 DN300 pillar hydrants ($176 total for ≥100 units) vs. 6 DN150 hydrants ($660 total for ≥100 units)-saving 73% on equipment cost.

Simplified pipeline network: Fewer hydrants mean fewer main pipeline branches. For a 20,000㎡ airport tarmac, 3 DN300 models need 3 pipeline connections, vs. 10 DN150 models (10 connections)-reducing pipeline material and labor costs by 60%.

4. Applicable Scenarios (Leveraging Large-Flow & Pillar Stability)

 

Large Industrial Parks: Petrochemical bases,automotive manufacturing plants-DN300 models supply large-volume water to suppress Class A/B fires in production workshops or storage yards.

Airport & Port Areas: Airport tarmacs,container ports-pillar-type grounding resists aircraft/tractor collisions, and large flow supports fire trucks in quickly extinguishing aircraft fuel or container fires.

Urban Large-Scale Venues: Stadiums,exhibition centers-auxiliary outlets enable simultaneous use by multiple on-site teams, while the main outlet connects to fire trucks for large-area water supply.

Highway Service Areas & Logistics Centers: Large truck parking lots,cargo warehouses-DN200 models balance flow and cost, covering 5000~8000㎡ areas with minimal hydrant quantity.

 

5. Frequently Asked Questions (FAQ) – Focus on Pillar & Large-Flow Features

 

Why choose a pillar-type design instead of underground for large-flow needs?Underground hydrants have limited caliber (max DN150) due to burial space constraints, while pillar-type hydrants can accommodate DN200~DN300. Additionally, pillar-type models allow quick access to main/auxiliary outlets (no need to open underground covers), critical for large fires where every second counts.

Can the pillar height be adjusted for different scenarios?Yes. With a customization MOQ of 2000 units, we can adjust the height from 1.5m (for pedestrian-heavy areas) to 2.5m (for industrial zones with tall equipment). For airport tarmacs, we offer a 2.2m height to match fire truck hose connection height (avoids bending hoses).

How to maintain the large-caliber valve core?The brass valve core is designed for low maintenance: ① Every 6 months, apply food-grade lubricating oil to the valve stem (via the top oil injection port) to ensure smooth operation; ② Every year, open the main valve for 5 minutes to flush debris from the flow channel. No disassembly is needed-maintenance takes <30 minutes per unit.

Is the hydrant compatible with CA-Fire's foam nozzles and concentrates?Absolutely. The auxiliary DN65/DN80 outlets can connect directly to PQ series foam nozzles, and the main DN200/DN300 outlet works with PC/PCL foam generators. When paired with CA-Fire 3%/6% AFFF concentrates, it can deliver large-volume foam mixtures for Class B fires (e.g., oil storage tank spills).
