Rubber Slurry Hose Flexible Rubber Build Enhanced Particle
Resistance Long Service Cycle
Description
The Hongruntong Mining Hose is engineered for mining operations
facing extreme environmental and chemical challenges. Designed for
high-pressure slurry transport, corrosive material handling, and
demanding surface or underground deployments, this hose combines
multi-layer synthetic reinforcement with specialized chemical- and
abrasion-resistant rubber compounds. Its design emphasizes
structural integrity, flexibility, and longevity under the harshest
mining conditions, including acidic tailings, high temperatures,
and UV exposure.
Case Study
In 2020, a lithium mine in the Atacama Desert, Chile, required a
hose solution for transferring highly alkaline lithium-bearing
brine through long pipelines across desert terrain. The mine had
previously experienced frequent hose failures due to corrosion, UV
damage, and abrasion from suspended solids. Hongruntong supplied a
16-inch diameter Mining Hose with a triple synthetic reinforcement
design, an inner lining resistant to strong alkaline solutions, and
an outer layer formulated for UV and sand abrasion resistance.
The hose was deployed across a 2-kilometer pipeline with multiple
bends and steep inclines, operating continuously under temperatures
reaching 60°C during daytime and dropping to -10°C at night. Over
24 months of operation, the hose maintained integrity, with no
leaks, wall degradation, or chemical breakdown. Engineers reported
a 50% reduction in maintenance costs compared to prior hoses and
observed consistent brine flow rates, which improved overall
production efficiency. The hose’s flexibility allowed safe
installation over uneven desert terrain, and its chemical-resistant
lining prevented contamination of the transported lithium solution,
safeguarding both product purity and operational safety.

Features
Extreme Chemical Resistance
The inner rubber lining is formulated to resist a broad spectrum of
corrosive substances, including acidic tailings, alkaline brines,
and process chemicals. Extensive chemical immersion testing shows
no swelling, cracking, or loss of flexibility even after prolonged
exposure, ensuring safe transfer of corrosive mining fluids. This
makes the hose particularly suitable for lithium, phosphate, and
rare-earth mineral operations where chemical exposure is a critical
concern.
High Temperature Tolerance
The hose maintains structural integrity and flexibility in
temperature ranges from -30°C to 75°C. Heat-resistant compounds
prevent softening, while low-temperature flexibility ensures that
the hose does not become brittle underground or during night-time
operations in deserts. Field tests demonstrated that hoses retained
performance even under repeated thermal cycling, making them ideal
for regions with extreme diurnal temperature variations.
Multi Layer Reinforcement for Pressure Stability
The triple synthetic fiber reinforcement distributes internal
pressure evenly and provides resistance to bulging, bursting, or
deformation during high-pressure slurry transport. This design
allows hoses to safely operate under pressures up to 25 bar and
withstand repeated pump start-stop cycles. Reinforcement layers
also contribute to excellent fatigue resistance, essential for
continuous operation in demanding mining applications.
Abrasion and UV Protection
The outer layer incorporates specialized abrasion-resistant
compounds and UV inhibitors, protecting the hose from mechanical
wear, sand impact, and solar degradation. This feature is crucial
for long-term surface deployments, open-pit mines, and desert
operations where hoses are exposed to sunlight, shifting sand, and
mechanical contact with rocks or equipment.
Applications
Corrosive Slurry and Brine Transfer
Suitable for transporting chemically aggressive slurries and brines
over long distances, the hose protects product purity and prevents
environmental contamination.
High Temperature Surface Mining
Designed for use in open-pit mines with extreme temperature
fluctuations, maintaining flexibility and durability under direct
sunlight and desert heat.
Tailings Disposal in Chemically Aggressive Environments
Effective for moving tailings containing acidic or alkaline
components to disposal or processing sites, reducing wear,
preventing chemical breakdown, and extending hose service life.
