Advantages of polyethylene pipe in mining

Nov. 09, 2021

The two most important factors in selecting pipe materials for mining applications are safety and reliability.  The pipeline must be rust-resistant, bend-resistant, and corrosion-free.

 

HDPE pipe can be used in a variety of mining applications including water transfer, coal washing, general mineral processing, sluicing, and slurry transfer. Our pipe has been developed specifically to meet the unique requirements of hard rock and specialty mining operations. It provides safe, easy-to-install, economical fabrication for air separation structures, manholes, and mines, hoist bore liners, recovery tunnels, drifts, conveyor covers, and many other applications. Our pipe products easily handle the harsh conditions of mine entrances, rockfall protection, and storage tunnels. HDPE pipe is commonly used in mines, shafts, tunnels, gangways, and dumpsters.

Some of the proven benefits of HDPE pipe for mining applications include:

 

Chemical and abrasion resistance

ΔHDPE pipe will not rust, corrode, tumor, or support biological scaling or growth, providing excellent chemical resistance compared to traditional pipe materials.

△HDPE pipes are smooth inside, ensuring low resistance even at high flow rates.

△Many plastic pipes offer the benefits of corrosion and chemical resistance that are superior to traditional metal pipes, but HDPE pipes uniquely combine these attributes with the aforementioned advantages of hot-fusion joints, flexibility, and fatigue resistance.

△HDPE is unaffected by bacteria and fungi and is resistant to many organic substances.

△ HDPE pipe's tough corrosion resistance makes it ideal for all types of culverts, sewers, and underground drainage systems in mining applications, both above and below ground.

 

Pressure Surge Resistant

△PE pipe for mining applications is semi-rigid and can withstand high external loads and high internal pressure fluctuations. Its flexible characteristics expand with pressure fluctuations, extending the life of the pipe and reducing maintenance costs.

ΔHDPE pipe can withstand very high internal or external pressures, even at depths of hundreds of feet. It has a longer service life than stainless steel. Your operation can run smoothly at the highest level while ensuring that your facilities, people, and environment are always protected

△ What makes HDPE pipe so popular as a conveyance or drainage pipe is its combination of excellent hydraulics, surge resilience, and overall strength and toughness.

 

Easy to install

HDPE pipe is much easier to handle and install than heavier, rigid metal or concrete pipe sections, resulting in significant cost advantages and return on investment.

△ Because HDPE is about one-eighth the density of steel, it does not require the use of heavy lifting equipment during installation.

△Polyethylene pipe is structurally better able to withstand impacts than PVC pipe, especially in cold weather installations where other pipes are more prone to cracking and fracturing.

ΔHDPE's flexibility allows bending without additional fittings and can be easily installed in continuous lengths.

△Flexible and leak-free fittings allow for unique and cost-effective installation methods that rigid PVC and ductile iron pipe cannot be used with ball and socket joints.  In most applications, these alternative installation methods (horizontal directional drilling, pipe bursting, slip, plow and plant, submerged or floating pipe, etc.) can save significant time and money.

 

Low Cost

Polyethylene pipe is cost-effective and offers long-term cost advantages due to its physical properties, leak-free joints, and reduced maintenance costs.

△ The polyethylene pipe industry estimates a conservative 50-100 year service life for PE pipe.  This saves replacement costs for future generations. You want a pipe that's easy to install and will last forever.

△In addition to the life-cycle capital cost advantage of HDPE pipe, homeowners have the added cost savings of zero "allowable leakage" versus the typical 10% to 20% leakage rate of PVC and ductile iron.
