Mining Pipeline

1.Product Overview​​

Mining pipelines are specialized conveyance systems engineered for harsh mining conditions, featuring ​​superior abrasion resistance, impact tolerance, and corrosion protection​​ for transporting mineral slurries, tailings, coal powder, and other abrasive media.

​​2. Core Product Types​​

​​(1) Ultra-High Molecular Weight Polyethylene Pipe (UHMWPE)​​

​​Abrasion Resistance Index​​: ≥150% (vs. Q235 steel baseline)

​​Compatible Media​​: Mineral slurries (≤60% concentration), concentrated ores

​​Advantages​​: Lightweight (1/8 of steel pipe weight), self-lubricating, anti-scaling

​​(2) Ceramic-Lined Steel Pipe​​

​​Structure​​: Carbon steel outer layer + alumina ceramic liner (AL₂O₃≥95%)

​​Wear Resistance​​: 10x more durable than manganese steel

​​Temperature Range​​: -40°C to 350°C

​​(3) Steel-Rubber Composite Pipe​​

​​Structure​​: Seamless steel outer shell + wear-resistant rubber liner (natural/neoprene)

Impact Resistance​​: Withstands 20J/cm² impact energy

​​Application​​: Large-particle ore conveyance (≤150mm particle size)

​​(4) Reinforced HDPE Mining Pipe​​

Reinforcement​​: Steel wire mesh or fiber-wound construction

​​Pressure Rating​​: PN1.0-PN2.5MPa

​​Anti-Static​​: Surface resistance <10⁶Ω (GB3836 compliant)

​​3. Technical Comparison Table​​

​​4. Key Performance Metrics​​

​​Service Life​​: 8-10x longer than standard steel pipes in iron ore slurry (2m/s flow velocity)

​​Impact Strength​​: Continuous exposure to ≤200mm ore particles

​​Explosion-Proof​​: MT558.1-2005 mining safety certification

​​Flame Retardancy​​: VO rating (GB/T2408 standard)

​​5. Selection Guide​​

Match pipeline type to media characteristics:

​​6. Installation & Maintenance​​

​​Flange Seals​​: Use acid-resistant EPDM gaskets

​​Support Spacing​​: ≤2.5m for DN300 pipes (prevents sagging)

​​Inspection Interval​​: Liner wear check every 5,000 service hours

​​Emergency Repair​​: On-site patching kits with high-performance polymers

​​7. Quality Assurance​​

​​Material Testing​​: Batch verification of UHMWPE GUR values (≥5.0g/10min)

​​Pressure Testing​​: 1.5x working pressure for 30 minutes

​​Wear Validation​​: 1,000-hour slurry test bed endurance trials

​​Certifications​​: Mining Product Safety Certification (MA/KC)

​​8. Service Commitment​​

​​Engineering Support​​: Hydraulic calculations + 3D pipeline layout

​​Rapid Delivery​​: DN200-DN800 pipes available from stock

​​Onsite Guidance​​: Engineers available for specialized installations (underground/high-altitude)
