Mild Steel Filter
The above images, provided courtesy of Grade 2 Impact Blast Cleaning, show the flame spraying of Zinc onto a mild steel filter used in the water industry.
Water Treatment Plant
The photograph shows a Fylde Water Board Tower at Barnacre, UK. The tower was grit blasted to BS 4232, and then zinc sprayed to 175 microns (0.007”) followed by one coat of inhibitive sealer to Zn7/a. Fylde Water Board has adopted this Metallisation Protective System as their standard anti-corrosion treatment, as it has proved over many years to be the optimum for efficiency, economy and maintenance free operation.
Water Treatment Vessels
Eleven 12.19m (40ft) vessels, weighing 10,500kg each, together with nearly 300 smaller units, were treated with Metallisation Zn3/a anti-corrosive system for the North West Water Authority UK. This involved shot blasting to BS 4232 followed by metal spraying with zinc, and finally a coating of a passivating sealer. The main reasons for the Water Board adopting this system was its proven anti-corrosive qualities and the ease with which it can be over-coated with conventional paint.
