Hydrotransport of ores and mineral concentrates is a rapidly growing application at many mines. In hydrotransport, a slurry is pumped through the hydrotransport pipeline at rates of approximately 4 to 5 meters per second over distances of up to many km.
The slurry is generally an abrasive mixture generally consisting of water, sand, rocks and ore. The high velocities and abrasive nature of the slurry create rapid wear of the regular polyethylene pipelines and is particularly harsh on elbows and sweeping bends.
Conventional polyethylene pipes are rotated several times a year to even-out the wear on the inside of the pipe caused by the abrasive slurry.
Regular HDPE pipes when used to hydrotransport slurry require frequent maintenance, rotation, repair and replacement resulting in higher operating expenses and increased costs and process downtime.
PEXGOL crosslinked PEX pipes are well suited for aggressive hydrotransport slurry applications owing to their exceptional abrasion resistance and inherent low surface roughness.
PEXGOL pipes thus offer financial and operational benefits associated with increased production uptime and lower times lost in rotating and replacing worn polyethylene pipes.
