In late 2022, Denso Australia’s Protal 7700™ liquid epoxy was selected to protect one of the oldest gas pipelines in Australia. The pipeline boasts an OD of 400mm and extends from Moomba in Central Australia all the way to Adelaide, South Australia.
The project began with multiple bell-holes, (each ranging from 10-15m long) being created along the length of the pipeline prior to surface preparation and product application. Surface preparation of the substrate involved the removal of the previous coatings along the pipeline in order to rectify structural integrity in certain areas. Once these repairs had been completed, the pipe was then abrasive blasted to an SA2.5 standard and later coated with Protal 7700. The interface areas between the old existing coating and the newly, spray-applied Protal 7700 were accommodated with Denso Petrolatum Tape and Denso Glass Outerwrap (non-UV was ideal for this buried application).
In summary, the applied coating is expected to see out the life of the pipeline and the client has expressed that they are not only extremely comfortable using Protal 7700, but are also very happy with its application rates and overall performance.
