Reliable, Safe, Rugged, and Cost-Effective Pipe for Mining

Mining operations depend on reliable movement of water, slurry, tailings, and chemicals to keep production running safely and efficiently. Pipelines are the lifelines of these systems, connecting pits, plants, and tailings facilities across often harsh and remote environments.

From dewatering deep pits to transporting slurry over miles of rugged terrain, every pipeline in a mine plays a vital role. And with focus on productivity, cost control, and operational integrity, the choice of pipeline material has never been more important.

That’s where Composite Piping Technology’s MaxDR® delivers measurable advantages across every phase of mining operations. MaxDR is a high-pressure, fusible composite poly pipe that takes HDPE to where only fiberglass and steel have gone before.

Key Pipeline Applications in Mining

1. Slurry Transport. Pipelines moving slurries from the mine to the processing plant or from the plant to a port or tailings storage facility (TSF).

• Challenges: High internal pressure, abrasion, corrosion, and long distances.
• MaxDR Advantage: Composite reinforcement delivers higher pressure ratings with thinner walls – allowing for more wear while maintaining pressure capacity.  As an HDPE pipe, MaxDR has superb abrasion resistance. MDPE is available for additional abrasion resistance.

2. Water Supply and Dewatering. Mining operations requiring constant water movement – bringing in fresh or recycled water while pumping out groundwater or stormwater.

• Challenges: Variable flow rates, pressure fluctuations and erosion.
• MaxDR Advantage: Corrosion and abrasion-resistant, and lightweight, MaxDR can be installed quickly in remote terrain and support higher operating pressures ensuring long-term reliability.

3. Tailings Disposal. Slurry transported safely to tailings storage facilities (TSFs).

• Challenges: Highly abrasive, sometimes acidic materials that can wear down metal pipes.
• MaxDR Advantage: Smooth inner walls and high abrasion-resistant material extend service life, reduce maintenance, and minimize risk of ruptures.

4. Backfill Delivery. Pipelines to pump cemented paste or heavy slurry backfill into mined-out voids to maintain ground stability.

• Challenges: High density and abrasion of paste backfill, coupled with tight underground spaces.
• MaxDR Advantage: Its lighter weight and high strength make it easier to handle in confined tunnels, while its smooth interior maintains flow performance over time, and its flexibility supports bends without fittings.

5. Harsh Environment. Ability to stand up to the harsh conditions of above ground operations.

• Challenges: Piping installed and moved across harsh, uneven surface conditions with extreme temperature swings.
• MaxDR Advantage: MaxDR includes an outside protective layer of pipe grade PE4710 which includes ultraviolet (U.V.) stabilization to ensure years of high integrity operations and relocation.

6. Environmental and Chemical Systems. Pipelines to manage process reagents, fuel, and wastewater – materials that can be corrosive and environmentally sensitive.

• Challenges: Leak prevention, corrosion control, and chemical compatibility.
• MaxDR Advantage: Engineered composite construction combined with HDPE material ensures chemical resistance and long-term integrity, reducing risk and downtime.

Why Choose MaxDR Pipe Solutions for Mining

CPT’s MaxDR delivers a Measurable Difference in Performance and Value™ by combining the Strength of Composite with the Ease of Poly™.

A joint of MaxDR 350 is half the weight of the equivalent ID DR7 poly pipe due to a thinner wall strengthened by composite material, which means it uses less material while achieving higher operating pressures.  As a result, MaxDR maintains higher pressure performance while reducing the wall thickness of the pipe – making it lighter, easier to handle, less expensive to transport, and dramatically faster to fuse with standard fusing equipment. The fiberglass reinforcement layer allows for more internal wear while maintaining higher operating pressures. The rugged HDPE protective cover provides protection from rough terrain and U.V. rays.

MaxDR supports working pressures of 350, 550, and 750 psi.

MaxDR Performance Benefits:

• Higher pressure capacity with a thinner wall
• Larger internal diameter for greater flow and lower pumping costs
• Lightweight design for faster, safer installation
• Corrosion and abrasion resistance in aggressive mining conditions
• Faster fusion joints that reduce installation time and downtime
• Extended service life with minimal maintenance
• Lower total cost of ownership compared to steel or standard HDPE
