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.

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.
