A bitumen tape wrap system from Winn & Coales (Denso) Ltd was utilised for the repair of damaged pipework at the new HS2 terminus at London Euston train station.
Following damage to the existing factory coating, corrosion had already begun to inflict damage upon the pipe and had propagated underneath the coating itself, causing it to delaminate. To eliminate further damage, the Denso™ Bitumen Tape Wrap System was applied to not only protect the pipe from the effects of further corrosion, but to provide a large degree of mechanical protection too.
Winn & Coales (Denso) Ltd are leading manufacturers and suppliers of corrosion prevention and sealing systems. The bitumen tape wrap system supplied for the project was comprised of a bitumen-based primer (Denso Primer D™), a heavy-duty PVC-backed bitumen tape (Densoclad 70™ Tape), and a protective outerwrap (Denso™ Glass Outerwrap). The protective outerwrap offers exceptional mechanical and impact strength for buried pipes exposed to aggressive backfill conditions. Once applied and fully cured, the whole system provides a long-term protective coating that is ready for immediate service.
