BioZinalium coating system, creating sustainable solutions for our customers

Posted: Tuesday 25th March 2014

Saint-Gobain PAM UK has launched an enhanced external protection system for its range of ductile iron pipes, which not only provides outstanding sustainability credentials, but also reduces the overall cost of ownership when compared to other protection systems.

In an industry where there are increased pressures to achieve low leakage levels and to guarantee a durable infrastructure network, BioZinalium® is Saint-Gobain PAM’s practical response to the genuine concerns of water network investors, operators and managers.

The enhanced protection system retains the active properties of the existing Zinalium® (Zn-Al 85/15) alloy, which has now been enriched with copper, an antibacterial agent to reduce the potential risk of localised bio-corrosion.

Exclusive to Saint-Gobain PAM UK, BioZinalium® has been launched after many years of investigation and development into protection against bio-corrosion, and the proven research that up to an estimated 84 per cent of the service life of a pipe is determined by its external coating*.

The added enhancement of the copper enables the bactericidal properties of this metal to be leveraged to reduce the possible risk of localised bio-corrosion. BioZinalium® therefore provides a brand new way of reducing this risk and thus impacting positively on the durability of the pipes by reducing the total cost of ownership. This protection system is suitable for over 90% of soils in the UK without the need for any further protection. An estimated saving of a minimum of 3% has been identified when compared to alternative external coating systems.

Olga Luengo-Gonzalez, Marketing Manager - Water and Sewer Pipelines, comments: “BioZinalium® has been developed to help target a very real issue in the industry. Our extensive research has clearly identified the coating as the main contributor to the service life of pipes. Our combination of aluminium, zinc and copper improves the service life of the pipes by up to three times compared to traditional zinc only protection systems, as well as helping to reduce the risk of bio-corrosion.”

As sustainability is also a key issue, the new finishing coating is produced using an emulsion of water-based resin, which contributes towards reducing emissions of volatile organic compounds (VOCs) into the atmosphere, and complies with sanitary recommendations for reducing the risk of exposure to Bisphenol A (BPA) for the population and environment.

The enhanced coating is available on Natural® and Blutop® water pipes for diameters up to and including DN600, and there is full compatibility between the current and new ranges. BioZinalium® complies with European Standard EN545:2010 and International standard ISO 2531.
