Project Details
Winn & Coales (Denso) Ltd, leading manufacturer and supplier of corrosion prevention and sealing systems, recently supplied their abrasion resistant outerwrap (ARO), Denso Bore-Wrap™ for use on sections of a new 2.7km natural gas pipeline constructed to service Kilroot Power Station, situated on the north shore of Belfast Lough. The contract, secured by GMC Utilities Group with their joint venture partner Rayden Engineering, is part of a £600m decarbonisation scheme to transform the coal fired power station and create a new low carbon energy park.
The welded steel pipeline from Marshallstown Above Ground Installation (AGI) to Kilroot AGI was mainly installed by open cut methods, but at road crossings, including one on the A2, the pipe was installed by horizontal directional drilling (HDD). To ensure that the integrity of the anti-corrosion coatings on the pipe was maintained, Denso Bore-Wrap was applied to these sections prior to pulling the pipe under the roadways. Once pulled through, the ARO showed no signs of damage, indicating no damage to the coatings underneath and clearly demonstrating the exceptional mechanical protection offered by the system.

Denso Clear Outerwrap is applied to compress the ARO and aid curing.
The surface of the Clear Outerwrap is perforated to allow excess resin, water, and CO2 from the reaction to escape.
