Long-Distance High-Volume Fire Water Supply Hose is a large-diameter hose specifically designed for rapidly delivering large volumes of firefighting water from natural water sources far from the fire scene (such as rivers and lakes) to the fire scene or pumps. Its core design objectives are to achieve high-volume delivery, low friction pressure loss along the route, and lightweight ease of long-distance deployment and coiling, while ensuring adequate pressure resistance.

Forged Aluminum Long-Distance High-Volume Fire Water Supply Hose Coupling is a coupling matched to the Long-Distance High-Volume Fire Water Supply Hose. Our hose coupling is based on the general technical specifications in the firefighting coupling field and the mature forging process for aluminum alloy couplings.

Structural Features:

Such couplings typically adopt a quick-connect structure, achieving connection through the engagement of claws and grooves with a small rotation angle, aimed at meeting the requirements for rapid deployment and disassembly in long-distance water supply. The body is integrally forged, and the internal flow passage is machined to ensure smoothness and reduce pressure loss during high-volume delivery.

Material:

The body material is generally 6061 aluminum-magnesium alloy, subjected to T6 heat treatment and anodized surface treatment. This combination of processes ensures lightweight while providing tensile strength and corrosion resistance far superior to ordinary castings, suitable for prolonged outdoor and high-pressure working conditions. Seals are typically oil-resistant rubber (such as NBR).

Main Type:

• Fire Layflat Hose V-Grooved Coupling, including Normal V-Grooved Coupling, Flange V-Grooved Coupling , Multi-lug V-Grooved Coupling
• Fire Layflat Hose Storz Coupling , including Normal Storz Coupling, Flange Storz Coupling, Multi-Lug Storz Coupling

Working Pressure:

For high-volume water supply scenarios, the nominal pressure (working pressure) of forged aluminum alloy couplings is typically not less than 2.5 MPa, with test pressure required to reach 4.0 MPa or even higher. Some high-pressure variants or specific specifications can have a design working pressure at the 4.0 MPa level to meet the higher outlet pressures required for long-distance pumping.

Key Characteristics:

• Lightweight and high strength: Forged aluminum alloy weighs significantly less than copper or cast iron couplings at the same pressure rating, facilitating long-distance handling and rapid deployment.
• Quick operation: Groove with Clamp or Storz-style connection supports "push and twist" locking, greatly shortening hose connection time compared to threaded couplings.
• Corrosion resistance and durability: The anodized layer effectively resists scale, chemicals, and UV erosion; the forged structure is dense and highly resistant to drops and impacts.

Main Applications:

Dedicated to high-volume, long-distance firefighting water supply systems. Typical scenarios include: pumping firefighting water from natural water sources far from the fire scene (such as rivers and lakes) through large-diameter hose mains to the fire scene; and serving as the connection hub between hoses and pumps, manifolds, or fire trucks in industrial fires such as petrochemical and large-scale warehousing that require high-volume cooling or foam supply.
