Scope of supply

The coating requirements are getting stricter due to the extreme conditions crane components suffer, such as: extreme temperatures (negatives or positive), corrosion areas in direct contact with salt (seaboard coastal areas with an exceed of salinity or hooks located on the decks of commercial vessels or in their supporting works), direct contact with salt water (e.g., submerged subsea components), direct contact with fresh water (hydroelectric plants), direct contact with chlorinated water (nuclear power station cooling pools), being the most extreme ones from coating specification point of view:

  • Subsea Pre-SALT: Because of being continuously submerged in ecosystems still unknown for its effects at the metals (6000m depth), the metallic components have to be protected from bacteriologic attack.
  • Auxiliary Hydro equipments: For having a precisely amphibious ambiguity, for being submerged or in dry sunlight, the difficulty of enduring both environments, makes the unions, seals and surfaces suffer and shortens their lifetime, and because of this they must be subjected to strict maintenance tests and inspections.

For the extreme cases just mentioned, as a result of its experience IRIZAR FORGE has developed specific instructions and procedures for protection in these applications, for example, to combine the welding beads with zinc- rich silicones and other specific seals.
