Denso Protal coatings offer reliable corrosion prevention.

Denso Protal, the fast-curing, high-build pipeline coating, was recently selected for a valve station remediation project on the Amadeus Gas Pipeline in Australia thanks to its solid reputation for providing many years of reliable corrosion protection.

Project details

This project focused on the remediation of 26 valve stations along the Amadeus Gas Pipeline, which spans 1,625 kilometres in Australia's Northern Territory. An economical and high-quality solution for corrosion protection was required, and Denso Protal 7200 was the answer.

Protal features

The Protal 7200 pipeline coating from Denso is designed for on-site protection of fittings, tie-ins, girth welds, repairs and more. It is an epoxy liquid coating that can be applied by brush or spray in a single coat, either in the field or at the shop. It cures very fast to allow quick handling and backfill times. It also offers high abrasion resistance, high temperature resistance up to 95 degrees C (203 degrees F), and high build of up to 50 mils / 1270 microns in one coat. This coating provides excellent adhesion, especially with FBE coated pipe. It also meets AWWA C-210-92 specifications.

The result

There are many examples of Protal 7200 offering long-lasting corrosion protection in applications across the globe. The Amadeus pipeline application is no exception. The Protal 7200 was applied to the pipework using a plural spray method. Brushes were also used to apply coating to the valves and flanges. To coat the approximately 1,300 square metres of pipeline involved with the project, more than 5,000 litres of Protal 7200 was used. The project was completed after 14 months, and the valve stations now have reliable corrosion protection that will last for years to come.
