1. Product Overview & Core Advantages

1.1 Product Overview

The 6" Dry Type Fire Hydrant is a specialized anti-freeze fire control device designed for cold climates, featuring a dry internal structure that avoids standing water-effectively preventing freezing and bursting in low temperatures. It is a reliable emergency water supply tool with convenient, flexible, and reliable operation, suitable for underground/above-ground installation in municipal roads, industrial parks, commercial districts, and residential communities in cold regions.

Key design features include: a split structure (upper/lower body) for easy maintenance; EPDM seals for leak-proof performance; galvanized standard parts for anti-corrosion; and a dedicated drainage system that keeps the internal cavity dry when closed. The hydrant's assembly flange is compatible with 4" outlets, ensuring flexible connection with fire hoses and fire trucks. With a working pressure of 16.5MPa and test pressure of 22.5MPa, it meets high-pressure emergency water supply demands.

1.2 Core Advantages

Anti-Freeze Dry Structure: No standing water inside the valve cavity when closed, eliminating freezing and bursting risks in low-temperature environments (suitable for ≤-20℃ regions).

High Pressure Bearing Capacity: Working pressure 16.5MPa, test pressure 22.5MPa-far exceeding basic emergency requirements, ensuring structural integrity under extreme conditions.

Reliable Sealing Performance: Adopts high-quality EPDM seals at key joints, with good oil resistance and aging resistance, ensuring long-term leak-proof operation.

Convenient Operation & Maintenance: Split upper/lower body design, turbine-driven valve stem, and dedicated wrench for flexible operation; standardized parts for easy replacement.

Corrosion-Resistant Materials: Galvanized bolts/nuts, steel connecting pipes, and brass (59-1) joints-resisting corrosion from soil, moisture, and industrial environments.

Drainage Guarantee: Drainage outlet is unobstructed when closed, quickly removing residual water to maintain internal dryness.

Flange Compatibility: Assembly flange matches 4" outlets, compatible with standard fire hoses and fire truck connections.

3. Installation, Operation & Maintenance Guidelines

3.1 Installation Requirements

Foundation Preparation: Install on a reinforced concrete foundation (≥C25 strength) with embedded fixed feet to ensure stability under water pressure and impact.

Flange Connection: Align the assembly flange with the pipeline flange; use EPDM gaskets and torque galvanized bolts evenly to avoid leakage.

Drainage System Check: Ensure the drainage outlet is unobstructed and connected to the municipal drainage network to prevent residual water accumulation.

Cold Climate Installation: For regions with ≤-30℃ temperatures, add a thermal insulation sleeve to the above-ground part and wrap the underground pipeline with anti-freeze material.

Sealing Treatment: Use sealant for threaded connections to enhance leak-proof performance; avoid damaging the surface paint during installation.

3.2 Operation Instructions

Pre-Use Inspection: Remove the top cover, check the drainage outlet for blockage, confirm the turbine and valve stem operate flexibly, and verify no debris in the valve cavity.

Valve Opening: Insert the dedicated wrench into the turbine assembly, rotate clockwise to open the valve-water flows into the cavity and is discharged through the 4" outlet; adjust the opening degree to control flow rate.

Connection & Fire Suppression: Connect fire hoses or fire truck suction pipes to the 4" outlet; ensure tight connections to avoid leakage during high-pressure water supply.

Post-Use Shutdown: Rotate the wrench counterclockwise to close the valve tightly; confirm the drainage outlet is unobstructed to drain residual water, then reattach the top cover.

3.3 Maintenance Tips

Quarterly Inspection: Check the surface paint for peeling (touch up promptly), verify the drainage outlet is unblocked, and ensure the valve stem operates smoothly.

Semi-Annual Lubrication: Apply anti-rust grease to the turbine assembly and valve stem to prevent seizing in cold weather.

Annual Pressure Test: Conduct a 22.5MPa hydrostatic test to confirm no leakage in the body, flanges, and seals.

Winter Preparations: Before freezing temperatures, fully drain residual water and inspect the drainage system for blockages; replace aged EPDM seals if needed.

Corrosion Protection: For coastal or industrial areas, apply anti-corrosion coating to the above-ground part every 1-2 years.

4. Packaging & Transportation

Packaging: Each 6" Dry Type Fire Hydrant is wrapped in PE film and foam padding to protect the body and components from scratches. Accessories (wrench, gaskets, bolts) are packed in a separate carton. Multiple units are loaded into export-grade wooden crates with reinforced corners for sea/air freight.

Transportation: Avoid stacking heavy loads on crates; protect from rain, impact, and mechanical damage during transit. Store in a dry, ventilated warehouse (temperature: -10℃~40℃) for up to 12 months.

5. Application Scenarios

Cold Region Municipal Infrastructure: Urban roads, residential communities, parks, and public squares in northern China, high-altitude areas, and cold countries.

Industrial Zones in Cold Climates: Factories, petrochemical parks, logistics warehouses, and power plants in low-temperature industrial areas.

Commercial Districts & Public Facilities: Shopping malls, hotel clusters, hospitals, schools, and stadiums in cold regions.

Transport Hubs: Railway stations, highway service areas, and ports in freezing climates.

6. Frequently Asked Questions (FAQ)

Q: What is the difference between dry type and wet type fire hydrants?A: Dry type hydrants have no standing water in the cavity when closed, suitable for cold regions to prevent freezing; wet type hydrants are filled with water, suitable for warm regions with ≥0℃ temperatures.

Q: Why is the drainage outlet important for this hydrant?A: The drainage outlet quickly removes residual water after shutdown, keeping the cavity dry-this is the core anti-freeze design to avoid freezing and bursting.

Q: What is the maximum low temperature this hydrant can withstand?A: It is designed for ≤-20℃ environments; for ≤-30℃, add a thermal insulation sleeve and enhance anti-freeze measures for the pipeline.

Q: Can the hydrant be installed both underground and above-ground?A: Yes. It supports both installation types-underground for municipal roads (only the top cover exposed) and above-ground for industrial zones (full body exposed with anti-freeze treatment).

Q: What materials are the seals made of?A: The seals are EPDM, which has excellent oil resistance, aging resistance, and low-temperature flexibility-ensuring leak-proof performance in cold climates.
