ATOFINA CHEMICALS, INC.

The Arkema Group

Arkema manufactures thousands of chemicals worldwide, determined to commit its activities in compliance with top safety and environmental standards. It manufactures chemicals for virtually all types of water treatment applications.

Arkema consolidates Vinyl Products, Industrial Chemicals and Performance Products. Arkema holds the top position due to its command over original polymerization techniques (ionic or radical polymerization) and advanced research related to the nanostructuring of polymers (molecular structures on a nano-scale, the nanometer being one billionth of a meter).

Arkema is an organization built on profit centers, and has earned strong and well known commercial rankings worldwide. Their industrial facilities in Europe and the U.S are audited by the ISRS (International Safety Rating System).

Arkema is in constant two-way dialogue with the local community and public at large, through its Common Ground® initiative. It is involved in updating local communities about changes and alterations in their industrial facilities and addressing to community expectations and opinions.

Arkema’s Water Products

Rilsan® Fine Powder

Rilsan® coatings have been used for water transportation equipments and water treatment plants since 1970. They combine thermal stability, physical durability, chemical resistance and mechanical integrity in a coating material that stands up to almost anything.

Durable and Strong

Water Supply Systems coated with Rilsan® Fine Powder enable metal parts to withstand years of intense use without altering the drinking water quality. Dirty water and effluent pipes used in aggressive environments have also been protected by Rilsan® Fine Powder coatings. The brand offers significant advantages over rigid thermoset counterparts such as FBE (Fusion Bonded Epoxy) resins.

Rilsan® Fine Powder coatings are virtually impervious to extreme pressures, chemicals and temperatures. They provide high dimensional stability, good resistance to stress cracking, low moisture absorption and have a low coefficient of friction which avoids abrasion.

Easy Application Techniques

Unlike thermosetting resins, Rilsan® is a fully polymerized thermoplastic, and as such requires no curing. It is available as ready-to-use powders with unlimited shelf-life. They have a sharp melting point which fuses the entire coat at once, giving products a uniform, glossy finish. This gives Rilsan® Fine Powders a Cost Performance Ratio that is tough to beat.

The diverse Rilsan® coatings provide optimum protection for all types of components used in water installations:

• Coating in fluidised powder bed
• Powder application on heated components
• Electrostatic spray on cold components
• Minicoat process on small components
• Rotocoating

Regulatory approvals

Rilsan® is a world class product that meets various international regulatory requirements.

The application of Rilsan® coatings on pipes and fittings in the water sector has been approved by two French standards, NFA 49-713 and NFA 49-714, and an American standard AWWAC224-01 which defines application parameters for the two-layer system. Rilsan® is certified in the following countries:

• France (Circular DGS/VS4/N°99.217)
• United Kingdom (WRAS and DWI certification)
• Netherlands (ATA certification)
• Belgium (NBN S 29-001 standard)
• Germany (DVGW certification)
• Italy (Circular 102)
• South Africa (SABS 1217 standard)
• Canada (Ontario Ministry of Energy and Environment, and Bureau de Normalisation du Québec - Quebec Standards Authority - BNQ   3660- 950)
• United States (NSF 61 certification)

Rilsan Case Studies

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.
