Reliable hydrometallurgy pipes withstand corrosion, abrasion, high temperatures and pressures.

Whether high pressure acid leaching (HPAL) acid, oxygen injection (POx), heap leaching or in-situ leaching (ISL) is employed, every pipe used in the leaching method must be able to withstand corrosion and abrasion in slurries under high temperatures and pressures.

Traditional materials involve maintenance repairs (rubber-lined carbon steel, RLCS or FRP), or high capital investment in exotic materials, such as SS316/304, duplex, titanium, which are expensive. RLCS in particular requires constant maintenance. That’s why Pexgol’s piping is a must.

Unlike these traditional solutions, Pexgol’s hydrometallurgy pipes are corrosion resistant, durable and impact resistant, with no need for special handling that rigid pipes may require. Pexgol’s long length options offer versatile design and installation planning.

Some of Pexgol’s advantages:
  • Typically lower-cost alloy compared to exotic materials.
  • Pipe material allows operating temperatures up to 110°C/230°F (suitable for general conditions of before autoclaves and after flash vessels).
  • Resistant to H2SO4, H2S in a variety of concentrations and to other leaching acids.
  • Smooth internal surface reduces energy.
  • Does not require special treatment such as levelling, preparation, or handling as some rigid pipes (FRP, GRP) may require.
  • Eliminates corrosion related to failures and repairs.
  • Resistant to cyclic fatigue.
  • Durable and impact-resistant.
