Mining Applications for HDPE Pipelines
HDPE (High-Density Polyethylene) is the go-to material for mining pipelines due to its durability, flexibility, and corrosion resistance. Here’s where it shines:
Water Supply & Dewatering
HDPE is ideal for transporting raw water to processing plants and removing excess groundwater from pits.
Its flexibility allows for easy rerouting as mine layouts evolve.
Slurry Transport
HDPE handles abrasive slurries (tailings, concentrates, overburden etc)
Civil Construction Applications for HDPE Pipelines
HDPE’s versatility makes it a top choice across a wide range of civil projects:
Water Supply & Reticulation
Used in potable water mains, rural supply lines, and irrigation networks.
PE100/PE112 grades meet Australian drinking water standards (AS/NZS 4020).
Stormwater & Drainage
Corrugated HDPE pipes (SN8+) are ideal for culverts, detention basins, and urban drainage.
Lightweight and easy to install in tight or unstable ground conditions.
Sewer Rising Mains
HDPE resists hydrogen sulfide corrosion far better than concrete or steel.
Electrofusion and butt welding ensure leak-free pressure systems.
Road & Rail Infrastructure
Used for under-road crossings, conduits, and service sleeves.
Flexible enough to handle ground movement and vibration.
Diversion Channels & Flood Mitigation
HDPE pipelines support rapid deployment in emergency works.
GEM’s large-diameter fusion capabilities are ideal for high-flow diversion systems.
Commercial Applications for HDPE Pipelines
Water Supply & Fire Services
HDPE is used for potable water mains and fire ring mains in commercial precincts.
PE100 pipes meet AS/NZS 4020 for drinking water and can be fusion-welded for leak-free fire protection systems.
Stormwater & Drainage
Corrugated HDPE (SN8+) is ideal for car parks, roof runoff, and detention systems.
Its flexibility helps navigate tight urban layouts and variable soil conditions.
Sewer & Trade Waste
HDPE resists chemical attack from trade waste (e.g., food courts, workshops).
Electrofusion fittings allow for compact installations in basements and service corridors.
Gas & Compressed Air
HDPE is used for low-pressure gas reticulation and compressed air lines in industrial zones.
Colour-coded pipe systems (yellow for gas, blue for water) simplify asset management.
Conduits & Sleeving
HDPE conduits protect electrical and comms cabling under slabs and roads.
Its smooth bore and flexibility make it ideal for trenchless installs (e.g., directional drilling).
Major Infrastructure Projects Using HDPE
Water Supply & Diversion Schemes
HDPE is used in long-distance trunk mains, irrigation channels, and inter-basin transfers.
PE100/PE112 grades handle high pressure, UV exposure, and aggressive soils.
Fusion welding ensures leak-free joints over kilometres of pipeline.
Flood Mitigation & Stormwater Management
Large-diameter HDPE (up to 2000mm) is deployed in culverts, detention basins, and bypass channels.
Corrugated HDPE options (SN8+) offer structural integrity with flexibility.
Transport & Rail Corridors
HDPE conduits protect electrical, comms, and drainage under roads and rail.
Its flexibility allows for trenchless installs and vibration resistance.
Mining & Energy Infrastructure
HDPE supports water supply, tailings return, and slurry transport across vast sites.
Lightweight and modular — ideal for remote deployment and rapid mobilisation.
Wastewater & Reuse Networks
Rising mains, pressure sewers, and recycled water systems rely on HDPE for chemical resistance and longevity.
Compatible with smart metering and asset tracking systems.
