Pipe linings and flanges.
Application was carried out in accordance with Belzona Know-How System Leaflet VPF-2.
Belzona’s electrical isolating properties form a barrier to the electrolytic cell set up by the dissimilar metal thus stopping galvanic corrosion. The previous vulcanized rubber coating had failed in less than 6 months. These repairs were still in service four years later.
