Listed below are some examples of failures that have been investigated.

Fertilizer Plant (NSW)

Collapse of Conveyor Gantry

A fully laden conveyor gantry collapsed in service causing significant structural damage to the production area and the storage shed as well as the loss of the gantry itself.

A detailed study of the products of corrosion in metals recovered from the plant identified partial and complete chemical reactions that contributed to corrosion and excessive metal loss resulting in the demise of the gantry.

A Power Station

Failure of Fire Hydrant Lines Attributed to MIC

Loss of water pressure in the fire service lines necessitated removal and sectioning of the pipes.

The pipes were blocked with substantial tubercles, a result of stagnant water and microbiological activity.

A Sydney Hospital

Failure of Potable Water Storage Tanks

Stainless steel water storage tanks had corroded, especially at and above the maximum water level, within twelve months of installation.

Cummins Diesel

Failure of Turbo Heat-Exchanger

Unexplained corrosion of the turbo heat-exchangers in imported large diesel motors was causing concern even though the cooling fluid was allegedly drained during shipment.

Rail Terminal (Hunter Valley)

Failure of Water Supply Piping

Perforation of this main had occurred in several places showing all the hallmarks of stray current corrosion.

Metso

Failure of Waste Treatment Fabrication

Premature failure at the welds of a waste treatment mixer revealed that an unsuitable grade of stainless steel had been specified and used.
