Lincolnshire Pipebridges Protected With Denso Steelcoat System

Posted: Wednesday 30th January 2013

Engineering and coating contractors Repair Protection & Maintenance Ltd of Kellington, North Yorks, are currently applying Winn & Coales (Denso) Ltd’s Denso Steelcoat system to protect four pipebridges in Lincolnshire for the Environment Agency. Main contractors for the project are Interserve Construction Ltd.

The function of the pipebridges is to take away drainage water. There are two at Torksey, near Lincoln, which discharge drainage water into the nearby River Trent.

The contract also includes pipebridges at Shortferry and Foldingworth.

RPM has chosen the Denso Steelcoat system to give the long-term protection required for the pipebridges. The surfaces are first manually prepared by wire brushing / scraping to ST2, removing all rust and loose coating material, which consists of a previous bitumen coating on two of the bridges. Denso profiling mastic is then used to provide an even surface and provide a smooth contour over flanges etc. The Denso Steelcoat system then applied consists of : Hi-Tack Primer, Denso Hi-Tack Tape, Ultraseal Tape, followed by a final two coats of a moisture cured polyurethane topcoat.

RPM have undertaken this contract as a turnkey project by looking after the refurbishment of the air valves, replacing a pipe coupling and organised the access scaffolding.
