Large Diameter Tailings Slurry Hose

JIDONGDA Large Diameter Tailings Slurry Hose is specifically designed for complex long-distance, high-flow-rate material transport in mines. Compared to traditional steel pipes, the hose is more flexible, impact-resistant, significantly reduces pipeline vibration, and simplifies on-site installation.

Applicable scenarios include slurry discharge in mineral processing plants, tailings dam filling, underground mine backfilling, dredged mud transport, port mineral powder loading and unloading, and transport of various industrial solid-liquid mixtures. Leveraging the customized production capabilities of our local factory, we can provide one-stop pipeline solutions for mining companies and engineering contractors worldwide.

Product Structure and Materials

Large Diameter Tailings Slurry Hose: Each layer is integrally molded at high temperature and vulcanized, eliminating the risk of delamination. It is compatible with various pumping equipment and comes with multiple connectors:

1. Inner Rubber Layer: Wear-resistant natural rubber / High-wear-resistant synthetic rubber (NR/SBR/PU optional; PU lining is suitable for high-silica hard tailings, offering optimal wear resistance)

2. Reinforcing Layer: Multi-layer high-strength fiber curtain + steel wire spiral skeleton, evenly distributing pressure, preventing collapse under negative pressure conditions

3. Outer Rubber Layer: Weather-resistant, ozone-resistant, and UV-resistant synthetic rubber, resisting outdoor exposure and chemical corrosion in mining areas

4. Optional Connectors: Standard flanges, quick couplings, and custom-made metal ends according to drawings

Performance Testing and Quality Control

1. Wear Resistance Test: 72 hours of continuous wear with quartz sand mortar, mass loss ≤ 0.05g

2. Burst Pressure: Burst pressure reaches 3–4 times the working pressure, capable of withstanding instantaneous pressure impacts

3. Pulse Fatigue: 20 10,000 Pressure Cycles Without Cracking, Delamination, or Deformation

4. Bending Performance: No breakage or delamination at minimum bending radius

5. Media Resistance: Stable operation in acidic and alkaline slurry environments (pH 2–12)

Core Advantages

1. Wear-resistant and Long Service Life: Exclusive high-wear-resistant inner rubber formula significantly reduces erosion loss from hard particles, suitable for high-sand-content slurries such as quartz, iron ore, and copper ore.

2. Large Diameter and High Flow Rate: Covers all sizes from DN100 to DN1200, suitable for large-scale tailings discharge systems, improving conveying efficiency and reducing pumping energy consumption.

3. Impact-resistant and Explosion-proof Pipe: Multi-layer composite reinforced structure buffers pressure fluctuations, eliminating the safety hazards of pipe bursts caused by blockages or start-ups/shutdowns.

4. Easy Installation and Low Maintenance Costs: Significantly lighter than steel pipes, easy to lay and relocate, reducing maintenance downtime.

5. Excellent Corrosion and Weather Resistance: The outer rubber layer resists sun, rain, and mining area corrosion fog, ensuring stable performance during year-round outdoor operation. 6. Full-Specification Customization Service

The factory supports customization of length, diameter, pressure rating, connector style, and wear resistance rating of the lining to match various special project requirements.

FAQ

Q1. Which lining material should be chosen for high-abrasion quartz tailings?

A. For tailings with a high proportion of hard particles such as quartz and granite, PU polyurethane lining is the preferred choice. Under a 72-hour standard abrasion resistance test, the wear is significantly lower than NR and SBR rubber, and the service life can be increased by 2-3 times under the same working conditions. The technical team can match the optimal lining formula based on the slurry particle composition and pH value.

Q2. Can JIDONGDA customize pipe diameters, lengths, and pressure ratings for special mining projects?

A. Yes, our factory provides full-dimensional customization. We support non-standard lengths, full diameters from DN100 to DN1200, and multiple working pressures from 1.0 to 10MPa. Flanges, quick couplings, and metal ends can all be customized according to construction drawings. After providing project parameters, we will provide a solution and quotation within 24 hours.

Q3. What is the warranty period for JIDONGDA Large Diameter Tailings Slurry Hose, and what after-sales support is included?

A. Standard products have a 12-month warranty from the date of shipment. Damage caused by defects in raw materials or processes under normal operating conditions will be replaced free of charge within the warranty period. Professional mining pipeline engineers provide remote guidance for laying, installation, and routine maintenance; on-site technical services can be negotiated for large-scale mining projects.
