What mining buyers struggle with
Steel slurry mains corrode within 2–4 years, leak at every welded joint and need a 7-day shutdown each time a section is replaced. The capital cost is low but the lifetime cost is brutal — and unscheduled downtime in a copper concentrator costs USD 50,000–200,000 per day.
Why HDPE PE100 wins on mining slurry
HDPE has 1/8 the surface roughness of new carbon steel, so wear-per-pass is dramatically lower. PE100-RC adds notched-pipe resistance for buried sand-bedded runs where point loads would otherwise propagate slow cracks. Joints are heat-fused into a single monolithic line — there is nothing to leak. Replacement is rapid: a pipe-bursting crew can swap 200 m of dying steel main in a 2-day shift without trenching the access road.
Typical mining-grade specifications
