Winn & Coales Steelcoat 400 System has been used to protect North West Water's 27in. water mains crossing the rivers at Langdenholme and Loud Way in the Trough of Bowland, North Lancashire, UK. The work was carried out by Daniel Contractors Ltd.
The Denso Steelcoat System was used by North-West Water's contractors in a renovation programme on the two pipebridges. They were previously protected with a bitumen-based wrapping. All loose material was removed and subsequent holes and depressions were filled with Densyl mastic to provide a smooth profile prior to wrapping with tape. Denso Hi-Tack Primer was applied followed by Denso Hi-Tack Tape forming the main corrosion prevention layer. Denso Hi-Tack Reinforcing Tape was then spirally applied. Owing to the coldness of the pipes as a result of the water flowing through them, a hot blower paint stripper torch was used to gently heat and seal the wrap joint while installing the final wrap.
The completed wrap was finally given a two-coat application of Denso Acrylic topcoat in Forest Green to complete the tough, weather-resistant Steelcoat System, enabling Daniel Contracting to meet its client's requirement for a 20-year guarantee of surface finish.
