Lead/steel apparatus engineeringBuilt for acid, pressure and temperature.

Lead has proven itself in chemical apparatus engineering thanks to its corrosion resistance. We combine it with steel to build equipment that stays in service for decades.

Star tube coolers

Star tube coolers and tube bundle condensers are part of gas cleaning plants for zinc, copper and molybdenum production. Extruded internal fins ensure high heat transfer.

  • Lead tubes with extruded internal fins (star tubes)
  • Tube sheets in lead/steel construction
  • Hand lead burning (lead welding) of tube connections

Wet electrostatic precipitators & emission electrodes

Complete wet electrostatic precipitators (WESP) for submicron particles, heavy metals, acid and oil mist – plus components and spare parts for existing plants.

  • Gas cleaning for zinc, copper, sulphuric acid, titanium dioxide, viscose, methyl acrylate
  • Precipitator casings, collecting and emission electrodes
  • Dry insulation
  • Inspection, repair and general overhaul

Homogeneously lead-lined equipment

In homogeneous lead lining, lead is bonded metallurgically and without pores to the steel body. This makes equipment durable and highly corrosion resistant – a clear advantage against leaks.

  • Linings of electrolysis cells for copper and zinc
  • Autoclaves and reactors for hydrometallurgy (gold, nickel, molybdenum)
  • Storage tanks for sulphuric acid and process liquids
  • On-site fabrication of large, segmented vessels
