Discharge Hose Heavy Duty Reinforced Design High Flow Capacity Reliable Pressure Handling

Description

The Hongruntong Mining Hose is purpose-built for extreme mining environments where high-pressure slurry, abrasive materials, and chemical exposure are common. Each hose is constructed with multi-layer synthetic fiber reinforcement and a highly durable rubber lining, providing exceptional mechanical strength, flexibility, and chemical resistance. The hoses are designed to endure demanding mining conditions, including long-distance slurry transfer, tailings management, and dewatering operations.

Case Study

In 2021, a nickel mine in Indonesia experienced frequent failures of conventional hoses in their long-distance slurry pipelines. The mine faced issues with high-volume abrasive slurry, tropical heat, and high humidity, which caused rapid wear and chemical degradation of the hose linings. Hongruntong engineered a 14-inch diameter Mining Hose with quadruple synthetic reinforcement layers, optimized for high-pressure slurry transport and long-term abrasion resistance.

The hose featured a specially formulated inner lining resistant to corrosive and mildly acidic tailings water, as well as an outer layer capable of withstanding UV radiation and mechanical abrasion during surface deployment. Over a continuous 18-month operation period, the hoses performed flawlessly, even under frequent pump start-stop cycles and pressure surges exceeding 20 bar.

The engineering team reported a 45% reduction in maintenance and replacement costs, a significant improvement in pipeline uptime, and enhanced safety for personnel due to the reduced risk of sudden hose failures. Additionally, the hose demonstrated exceptional flexibility, allowing for installation along challenging terrain, including steep inclines, bends around rock formations, and transitions between underground and surface pipelines. Detailed monitoring confirmed minimal wall wear, excellent chemical resistance, and consistent flow rates throughout the operational period. This project showcased the Hongruntong Mining Hose’s ability to maintain integrity under the combined stresses of abrasive material, chemical exposure, and extreme tropical climates.

Specifications

Features

Quadruple Synthetic Reinforcement Layers
The hose incorporates four layers of high-tensile synthetic fibers strategically designed to distribute pressure evenly across the hose wall. This advanced reinforcement structure prevents bulging, deformation, and rupture under extreme high-pressure conditions. The multi-layer design also enhances fatigue resistance during repeated pressure cycles, a common challenge in long-distance slurry pumping. Laboratory testing demonstrated that hoses with quadruple reinforcement could sustain over 50,000 pressure cycles at 20 bar without structural compromise, representing a 60% improvement over standard double-reinforced hoses.

Optimized Anti Abrasion Inner Lining
The inner lining of the hose utilizes a proprietary rubber compound with exceptional wear resistance. Designed for highly abrasive slurries, this lining minimizes particle-induced erosion, ensuring wall thickness remains consistent over long operational periods. The material is engineered to handle slurry velocities up to 15 m/s, providing optimal throughput without premature degradation. This feature is particularly critical in pipelines transporting tailings, sand, and finely ground ores where abrasion is severe.

Thermal and Chemical Stability
The hose can operate safely in temperatures ranging from -30°C to 75°C, accommodating both underground cold conditions and surface heat exposure. Its chemical resistance covers a wide pH range from 3 to 11, allowing safe transport of mildly acidic or alkaline slurries, commonly found in nickel, copper, and gold mining operations. Extensive chemical immersion testing showed no significant swelling, cracking, or loss of flexibility after prolonged exposure, confirming long-term operational reliability.

High Flexibility and Maneuverability
The combination of synthetic reinforcement and engineered rubber compounds enables the hose to maintain flexibility even at large diameters and long lengths. The hose can negotiate tight bends, vertical inclines, and complex routing without kinking or collapsing. This flexibility allows for safer installations in underground tunnels, pit slopes, and conveyor integration points. Field reports indicate a significant reduction in installation labor and time due to this maneuverability, particularly in complex, space-constrained mine layouts.

Applications

Long Distance Slurry Pipelines
Ideal for transporting mineral slurries over distances exceeding several hundred meters, the hose maintains pressure integrity and consistent flow rates, reducing energy consumption and minimizing pipeline maintenance.

Tailings Disposal Systems
Designed for transporting abrasive tailings to disposal sites or treatment ponds, the hose offers high wear resistance and chemical compatibility, extending operational life and enhancing environmental safety compliance.

Dewatering and Water Management
Perfect for pit and tunnel dewatering, the hose safely handles water removal under high-pressure pumping and abrasive sediment conditions. The chemical resistance also allows handling of process water containing residual reagents or acids without damage.
