Frost-Proof Pressure-Regulating Fire Hydrants

(Outdoor Fixed Water Supply Hub for Cold-Climate Fire Rescue)

 

1. Product Name & Positioning

 

Full Name: CA-Fire SSF150/65-1.6 Series CCC-Certified Frost-Proof Pressure-Regulating Fire Hydrants (Ductile Iron, DN150 Outlet, Flange Connection)

Abbreviation: CA-Fire SSF Frost-Proof Fire Hydrant

Core Positioning: A fixed outdoor fire water supply terminal with dual functions of anti-freezing and pressure stabilization-fundamentally different from our previous mobile foam tools (e.g., PQ foam nozzles),control valves (e.g., wet alarm valves) or foam concentrates (consumables). It serves as the direct connection point between municipal fire water pipelines and fire hoses, designed exclusively for cold regions where ordinary hydrants freeze and burst in winter. With ductile iron durability,1.6MPa pressure regulation and compatibility with water/foam mixtures, it ensures reliable outdoor water supply for fire rescue-filling the gap of ordinary hydrants that lack cold resistance and pressure control.

 

2. Core Product Advantages (Distinct from Ordinary Hydrants & CA-Fire Equipment)

 

1. Frost-Proof Structure: No Freezing in Low Temperatures (≤-25℃)

Unlike ordinary outdoor hydrants (prone to freezing and cracking at -5℃), this product adopts a "underground drainage + insulation" design:

Underground Drainage Valve: A built-in drain valve is installed in the underground section (below the frost line). After use, opening the valve drains all residual water in the hydrant body-preventing water from freezing and expanding to crack the ductile iron shell (a common failure of ordinary hydrants in winter).

Insulated Upper Body: The above-ground part is wrapped with a high-density polyurethane insulation layer (thickness ≥50mm) and an anti-UV outer casing-maintaining the internal temperature above 0℃ even when the ambient temperature drops to -25℃, avoiding ice blockage in the water channel.This design eliminates the need for manual winter insulation (e.g., wrapping with cotton felt) for ordinary hydrants, reducing maintenance workload by 80%.

2. Built-In Pressure Regulation: Stable Water Supply for Fire Hoses

A key function not found in ordinary hydrants (which lack pressure control):

1.6MPa Fixed Working Pressure: The hydrant integrates a pressure-regulating valve that stabilizes the outlet water pressure at 1.6MPa, even if the municipal pipeline pressure fluctuates (e.g., 1.2-2.0MPa). This prevents high-pressure water from damaging fire hoses (e.g., bursting 65mm standard hoses) or low-pressure water from reducing spray range-critical for consistent fire suppression efficiency.

Pressure Relief Protection: If the inlet pressure exceeds 2.0MPa, the pressure-regulating valve automatically releases excess pressure to protect the hydrant body and downstream equipment (ordinary hydrants rely on external pressure relief valves, increasing installation costs).

3. Ductile Iron Durability: Withstands Outdoor Harsh Conditions

Made of high-strength ductile iron (tensile strength ≥420MPa), far more durable than ordinary gray cast iron hydrants:

Impact Resistance: The body can withstand accidental collisions from vehicles (≤5kN impact force) without deformation-suitable for busy municipal roads or industrial park entrances (ordinary cast iron hydrants crack under 3kN impact).

Corrosion Resistance: The external surface is treated with a double-layer anti-rust coating (epoxy primer + polyurethane topcoat), passing 500-hour salt spray tests-resists humidity, industrial dust and minor chemical vapors (e.g., near gasoline stations), service life extends to 20-25 years (vs. 10-15 years for ordinary hydrants).

4. Water/Foam Mixture Compatibility: Synergy with CA-Fire Foam Systems

Unlike some hydrants that only support water, this product is designed to work with CA-Fire's foam systems:

It can supply not only pure water but also water-foam mixtures (from PHYM foam tanks or PC foam generators) to downstream PQ foam nozzles-forming a complete "hydrant → foam system → nozzle" fire suppression chain.

The internal water channel has no dead corners, avoiding foam residue accumulation (which causes clogging in ordinary hydrants) and ensuring smooth flow of foam mixtures.

5. Low Customization Threshold (MOQ 100 Units): Adapt to Regional Needs

Ordinary hydrants often require MOQ ≥500 units for customization, but this product supports logo,packaging and graphic customization with just 100 units:

Branding Customization: Laser engraving of municipal logos or project numbers on the hydrant body (e.g., "City Fire Department 2024") for asset management.

Packaging Customization: Wooden cases or pallets tailored to regional transportation needs (e.g., waterproof pallets for rainy Southeast Asian regions, insulated packaging for northern cold areas).

4. Applicable Scenarios (Leveraging Frost-Proof & Pressure-Regulating Advantages)

 

Cold-Region Municipal Roads: Northern China,Canada,Russia-installed on sidewalks or green belts, providing reliable water supply for winter road or residential building fires (ordinary hydrants are inoperable due to freezing).

Industrial Parks & Factories: Chemical parks,automotive manufacturing bases-ductile iron body withstands equipment collisions, and pressure regulation protects industrial-grade fire hoses (e.g., 100mm large-diameter hoses).

Gasoline Stations & Oil Terminals: Outdoor fuel storage areas-compatible with foam mixtures, enabling quick connection to PQ foam nozzles for Class B (liquid) fire suppression.

Large-Scale Residential Communities: High-rise residential areas in cold regions-fixed installation near fire hydrant cabinets, ensuring fire trucks can connect and draw water within 1 minute (faster than mobile water sources).

 

5. Frequently Asked Questions (FAQ)

 

How does the frost-proof function work in extremely cold weather (-30℃)?The underground drain valve must be opened to drain residual water after each use-this is the core of anti-freezing. For -30℃ environments, we recommend adding an optional electric heating cable (MOQ 50 units) around the underground section, which maintains the drain valve at 5℃-10℃ and prevents it from freezing shut.

Can the pressure be adjusted to less than 1.6MPa?No, the 1.6MPa pressure is factory-calibrated to match global standard fire hoses (e.g., NFPA 1961,GB 6246). Lower pressure would reduce the spray range of fire hoses (e.g., a 65mm hose's range drops from 20m to 12m at 1.0MPa). If you need lower pressure for special scenarios, we can provide custom pressure-regulating valves (MOQ 200 units).

What's the difference between this hydrant and your previous foam nozzles?They serve opposite roles: This hydrant is a fixed water supply terminal (provides water/foam mixture to the system); foam nozzles are mobile spray tools (use the mixture to produce foam). A complete fire system needs both-hydrant supplies water → foam generator/concentrate mixes → nozzle sprays foam.

How to install the hydrant to ensure frost resistance?The underground drain section must be buried below the local frost line (e.g., 1.2m deep in northern China, 0.8m in central China). We provide a "frost line measurement guide" for different regions-installers can follow it to determine burial depth, avoiding freezing due to shallow installation.
