Densopol Protects Outfall Pipeline

Posted: Thursday 24th June 2010

Winn & Coales’ Densopol 80 Tape System was recently selected to protect the field joints on the Alkimos outfall pipeline situated 40km north of Perth, Western Australia. It was supplied by Denso (Australia) Pty Ltd of Brunswick, Victoria, a subsidiary of Winn & Coales International Ltd. The project is part of the Alkimos Wastewater Treatment Scheme and is an alliance between the Water Corporation and the private sector, being named the Almimos Water Alliance.

The outfall pipeline is a 3.7km long 1270mm diameter MSCL pipe, comprising 294 joints which have been protected. The Sintakote pipe supplied by Tyco Water was delivered to site and then a concrete weight coating was applied.

At the cutback area Denso Primer ‘D’ was first applied , followed by the Densopol 80 Tape, spirally wrapped incorporating a 55% overlap. This effectively gives a protective coating of 4mm (4000 microns) prior to the cutback areas being in-filled with concrete.

The 3.7km long ocean outfall pipeline was buried up to 4 meters below the beach and sits in a trench on the seabed some 8-123 metres below sea level. Towards the end of the pipelines the depth of water is between 25-30 metres.
