Can both DN65 outlets work simultaneously for fire suppression?

Yes, both DN65 outlets of this fire hydrant are engineered to operate simultaneously for fire suppression. The DN100 inlet provides a robust water supply, ensuring sufficient flow and pressure to support both outlets without performance degradation. The hydrant's internal flow distribution system is designed to evenly split water between the two DN65 connections, maintaining consistent pressure and flow for each hose.

This dual-outlet capability allows firefighters to deploy two hoses at once, enabling simultaneous suppression of multiple fire points or supporting different firefighting tools, such as foam applicators or spray nozzles. This design enhances operational flexibility, reduces response time, and ensures reliable performance in critical emergency situations, making it a valuable asset in modern fire protection systems.

fire hydrant ground--How to maintain the aluminum couplings to prevent oxidation?

Proper maintenance of aluminum couplings is critical to prevent oxidation and ensure reliable fire suppression performance. After each use, thoroughly clean the couplings with a soft brush to remove dirt, debris and residual water, as moisture trapped in crevices is a major trigger for oxidation. Avoid harsh chemical cleaners that can damage protective surfaces.

Inspect the couplings regularly for signs of oxidation, such as discoloration or pitting, and address minor issues promptly. If the anodized or painted coating is chipped or worn, touch up with matching anti-corrosion paint immediately to seal the aluminum surface. Apply a thin, food-grade or industrial-grade lubricant compatible with aluminum to the threaded and sealing areas after cleaning; this reduces friction during connection and creates an additional barrier against moisture and air.

Store the couplings in a dry, well-ventilated environment away from high humidity or salt spray. Avoid prolonged contact with corrosive substances, and ensure all connections are tightly sealed when not in use. Consistent maintenance protects the aluminum's integrity, extends service life and ensures optimal functionality in emergency situations.

fire hydrant ground--How to connect the DN100 inlet to the water pipe?

More details

Flange Bolt Connection

The DN100 inlet of this fire hydrant ground adopts a standard flange connection. Align the hydrant's inlet flange with the matching flange of the water supply pipe, ensuring the bolt holes correspond perfectly. Insert high-strength bolts through the holes and tighten nuts evenly to fix the two flanges firmly together. This mechanical connection is stable and suitable for outdoor water supply systems, bearing water pressure without loosening.

Sealing Gasket Installation

Place a professional sealing gasket between the DN100 inlet flange and the pipe flange. The gasket is usually made of high-pressure resistant rubber or composite material, matching the flange size precisely. When tightening the bolts, the gasket is compressed evenly to fill tiny gaps, blocking water leakage. This step ensures a tight, long-lasting seal between the hydrant and the water pipe under working pressure.

Alignment and Final Fixing

Keep the fire hydrant vertical and the DN100 inlet concentric with the water pipe to avoid eccentric stress. Tighten the bolts in a diagonal order gradually to ensure even pressure distribution. After connection, check the flange clearance and sealing surface carefully. This correct installation method avoids deformation, guarantees stable water flow, and maintains reliable long-term performance of the fire hydrant.
