  • CUSTOMER: Vancouver, British Columbia, Canada Tug boat operator. Tugs used for hauling log booms up and down the coastline. Original application had taken place in 1996. Sections of the kort nozzle had to be replaced because of excessive internal corrosion. Much of the original coating and rebuilt areas were still in good condition and owner was happy to re-apply Belzona once the new sections were in place and welding complete.
  • APPLICATION DATE: August 2001
  • PROBLEM: Bi-metallic corrosion had eroded much of the metal and welds adjoining the stainless steel insert positioned in the center of the nozzle.
  • PRODUCTS:
    Belzona® 1311 Ceramic R Metal
    Belzona® 1321 Ceramic S Metal
  • SUBSTRATE: Mild and stainless steel.
  • APPLICATION METHOD: Application carried out in accordance with Belzona® Know-How Leaflets SOS-1 & 2
  • BELZONA FACTS: Using Belzona® eliminated the need to do extensive welding to restore the lost metal. This was limited to repairing holes in the kort nozzle which is also used as as radiator to cool the engine. Excessive welding also causes stress cracking which can create a major problem during the dry docking as the vessel cannot be put to sea if it is not able to pass a pressure test. Re-building with Belzona® 1311 eliminates all these problems. Coating the repaired area with Belzona® 1321 improves the abrasion resistance of the surfaces and eliminates any bi-metallic corrosion.
