Pipelines

An early and successful use of Metal Spray in Australia was on the second Warragamba pipeline (3m diameter and 22km long) built between 1964 and 1969. The first had been coated with the same heat-cured zinc silicate invented by Victor Nightingall and first used on the Morgan-Whyalla pipe line. While these have since been repainted several times, this has been due to delamination of the various over-coating systems and the underlying flame-sprayed Zinc TSZ is still sound. These pipelines supply 80% of Sydney’s water supply.
