Newcrest Mining – Lihir,
Heavy Fuel Oil Tank – Ultra High Build Epoxy Tank Lining
APPLICATION OF INTERZONE 485 TO 4,300 SQUARE METRES
1.5MM – 2MM
Applying UHB (Ultra High Build) coatings in a tropical environment requires the correct equipment, professional applicators and specialised experience.
The API 650 Tank with 14,000 tonne capacity HFO (Heavy Fuel Oil) at Newcrest Mining, Lihir Island – Papua New Guinea, required re-lining with Interzone 485, an Ultra High Build Epoxy coating system which is 99% solids, extremely viscous, has a short pot life, and is easily affected by high humidity.
Following Nukote’s success in lining the site’s Pre-Oxidation tanks with Nukote ST pure polyurea, Newcrest appointed Nukote for this important project.
Nukote successfully prepared and lined the base, walls, and roof supports of the 36.5m diameter tank with 1.5mm – 2mm of Interzone 485, applied with airless spray in a single coat. The underside of the roof was coated with Interzone 954.
Over 4,300 square metres of surface area was completed within the 20 days allowed for the project. This was less than half the time previous contractors had taken for a similar tank. Humidity was controlled using a 100kW Caterpillar dehumidifier.
Quality assurance was undertaken by Nukote’s in-house NACE accredited coating inspectors who ensured that all surface preparation and coating application met the specification’s requirements.
Nukote Australia Pty Ltd, with a successful track spanning over 15 years, is well regarded in the Australian mining industry for their expertise in applying all types of high performance coatings and linings.
The Nukote range of specialised elastomeric polyureas and polyurethanes include products formulated for high abrasion, high chemical exposure, hydrocarbon containment, and fire retardance.
Nukote products save mineral processors time and money because they are fast to apply and give a long service life.
Typical plant items lined or coated by Nukote include CIL tanks, water/process tanks, thickeners, SAG/Ball Mill Shells, concrete bunds, screen decks, structural steel, rail wagons, concentrate bins, and agitators.
