Weir Arterra UHMWPE Pipelines Boost Mining Efficiency, Cut Emissions

Weir introduced Arterra™ UHMWPE pipelines for slurry transport, offering mining operations a more durable alternative to standard HDPE. These pipelines feature a molecular weight seven times greater than HDPE, providing superior abrasion resistance and lower friction. A South Australian iron ore mine reported a significant lifespan increase for its pipelines. Arterra™ UHMWPE extended pipeline life from 4–6 weeks to 12–16 months. This durability reduces replacement frequency and associated downtime. In a 10 km copper-gold tailings transport test, Arterra™ pipelines lowered power consumption by 14.5%. This translates to an annual saving of 2.1 GWh and a reduction of 1,418 tons in carbon emissions. The company estimates annual energy cost savings of A$302,346. Arterra™ UHMWPE pipeline production generates 85% less CO₂ compared to steel. The manufacturing process also eliminates wastewater and toxic byproducts common with other materials. As mining companies focus on sustainability, these pipelines support reduced energy needs and emissions, enhancing both operational performance and environmental stewardship.
