Rilsan® protective coatings have been successfully used throughout the world.
In Japan
Japan experiences regular earthquake tremors. Many architects specify that suitably protected carbon steel pipe systems should be incorporated in building constructions. The conventionally used mechanically strong, ferrous metal pipes risk the onset of premature corrosion without a reliable protective coating.
For the past 20 years, many Rilsan® fine powder coated metal pipes and fittings have been installed in Japan. No reported failures have been attributed to the Rilsan® fine powders protective coating system.
In UK
The use of Rilsan® fine powder coated couplings and fasteners was pioneered in the UK and has become commonplace in the water industry.
The economic performance of Rilsan® fine powder coated fasteners compares favorably with alternative options including stainless steel. A service life of 50 plus years is commonly expected. Couplings and connector components are fluid-bed coated to obtain a film thickness of 250 to 350 microns, fasteners (nuts & bolts) are electrostatically sprayed to obtain film thickness of about 100 microns.
France and Australia
Throughout Paris, Rilsan® fine powder coatings are used extensively by the drinking water distribution networks.
In Australia, many distribution mains incorporating Rilsan® fine powder coated cast iron valves and couplings have been installed.
Oil Well Applications
When extracting oil from wells it is often necessary to increase the well pressure by injecting water. This water, often obtained from adjacent aquifers can be highly corrosive, containing carbon dioxide, hydrogen sulphide and bacteria. In Algeria, pipelines used for this purpose suffered repeated failures during the first 18 months of service. After replacing with Rilsan ® Fine Powder coated pipes, the lines are still intact after 5 years of intensive use.
