Denso Bore-Wrap™ Protects Power Station Gas Pipeline During HDD Installation

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 whilst the ARO is curing , then removed once fully cured . The undamaged Denso Bore-Wrap™ is visible after the pipe is pulled ( inset ).
