Water pipes to last 200 years with Plascoat PPA 571
Keywords: Pipes, Coatings
A long-term field test monitored by the Swedish Corrosion Institute has resulted in remarkable findings for thermoplastic coating manufacturer, Plascoat Systems Ltd.
After 11 years of being buried in the salty clay soils around Gothenburg, six water pipes coated with thermoplastic polyolefin alloys were dug up for examination and were found to be in outstanding condition.
The pipes showed absolutely no rusting, blistering, cracking or flaking. In fact all of the pipes were deliberately damaged before they were laid and the spread of these defects such as scratching, holes and blow marks were also found to be nil.
The Gothenburg Water and Sewage works has indicated that water pipes in similar conditions, coated with Plascoat PPA 571 would have a lifetime of over 200 years.
PPA 571 has been used for water pipes all over the world from snow making in Switzerland to the seaport in the USA city of Seattle. It has a wide range of potable water approvals including NSF61 and conforms to the requirements of FDA food contact.
The key benefits of PPA 571 include long-term adhesion (without the need for a primer), excellent edge coverage and extremely high levels of resistance to impact, abrasion, stress cracking, weather and pollutants.
PPA 571 is available for both fluidised bed dipping and electrostatic spraying.
