AGRU piping system with chemical resistance in Chile
For the application a PP-R piping system with white outside layer and a total length of 6 km was installed. Large quantities of abrasive industrial slurry accumulate at the company Ecometales which are then transported over a distance of 6 km to a treatment plant.
Different solutions were evaluated, such as the transport of the waste by trucks or the construction of a waste disposal piping system. Due to easier logistics and the resulting lower costs the installation of a pipeline was preferred.
Various requirements have to be met by this piping system, for example a temperature resistance
of up to 60 °C and a pressure resistance of up to 7.4 bar (108 psi). In
addition, the pipes are installed above ground which means that resistance against UV radiation is also required. A special challenge is the high abrasion which resulting from the transported slurry.
PP-R pipes with white UV resistant outside layer are the appropriate solution and have therefore been selected for this specific application.
This means excellent pressure resistance at high temperatures, greater
flexibility and impact resistance (very important for the conditions in
Chile). Another important feature is the very high abrasion resistance
of PP-R. Tests confirm that PP-R is more resistant to abrasion than
other materials like steel or concrete. For this application, pipes with
three different outside diameters are used:
Pipes with a length of 11.8 m were supplied to keep the number of welding joints to a minimum.
The so called PP-R multi-layer pipes are coextruded. The
white outside layer with a thickness of approximately 2.5 mm is
integrated in the wall thickness. The total wall thickness correlates
with international standards regarding the wall thickness for the individual diameters and pressure ratings
especially UV resistant. The white outside layer is specifically
stabilized in order to and guarantees the required lifetime of more than
5 years in Chile.
Excellent cooperation with our local representative “Agru
Tecnología en Plástico Sudamerica Ltda.” in Santiago de Chile insured
that project was quickly engineered and realised. In total 6,000 m of
pipes were installed. In addition to this product which is specially
manufactured for the application in the mining industry, AGRU has
developed a new piping system based on PE 100 / PE 100-RC
material, called “Mine-Line”. This piping system provides an extra
coextruded inside abrasion resistance layer as an innovative solution for slurry pipelines in the mining industry.
PLASTIC PRODUCTS FOR SEAWATER DESALINATION PLANTS
Today's modern seawater desalination Plant (SWRO) applies many plastic products manufactured from AGRU. Also for plants using other treatment technologies plastic piping and lining products are utilized.

Double containment system for waste water in Belgium
An extraordinary project regarding a double containment piping system was realised in Belgium close to Brussels. This project was executed in cooperation with Vink Belgium for the company JANS-SEN PHARMACEUTICAL.

Total solution for pure water in the Netherlands
The oil from the Schoonebeek oilfield in the Netherlands is viscous and fairly heavy which made extraction very difficult for a long time. The client NAM (Nederlandse Aardolie Maatschappij BV) decided to resume extraction by the end of 2007 and to employ a new technology whereby steam was injected into the ground.
