With the potential of carrying up to 11,000 liters of wastewater a second, an effective anti-corrosion lining with low maintenance and lifetime costs was required.
• The pipes were grit blasted internally and externally to ISO 8501-1 cleanliness standard SA 2½.
• For the internal pipe surfaces Polyglass VEF – a glass
flake vinyl ester acrylic co-polymer was applied at 1500
microns. VEF offers superior resistance to chemical attack in a severe immersion environment such as this.
• To give extra protection at key erosion points such as
bends, Corrocoat Armagel – an abrasion resistant vinyl
ester co-polymer containing glass flake and silicon carbide was used.
• For the external surfaces Plasmet ZF and Zip e was
applied. This durable glass flake coating provides effective protection in the aggressive atmospheric conditions found at waste water treatment plants.
