Potable water supply and distribution Ductile iron pipes and fittings system DN 60 to DN 1000 Comprehensive pipeline solutions

84% of the service life of a pipe is determined by its external coating.*

DN 60 to DN 600 Starting from 2014, the BioZinalium® coating will slowly replace the Zinalium® coating of the Natural® range. If you wish to know more about the external coating of the Natural® pipes, please check our BioZinalium® brochure. Saint-Gobain PAM - NATURAL® - Editi

The revolution towards... Always a coating ahead The decree of 27.01.2012 requires the water authorities to make a detailed assessment of their network assets and to set the objectives of reducing the leakage rate within a defined budgetary framework. These concerns have a direct influence on maintenance, renewal and extension programmes for water networks and also encourage the choice of reliable and durable pipes. BioZinalium® is a practical response of Saint-Gobain PAM to the genuine concerns of water network investors, managers and operators. Saint-Gobain PAM's research into zinc-based...

Natural® BioZinalium® DN 60 to 600* Zinalium® DN 700 to 1000 Aquacoat® acrylic pore sealer Copper enriched ZnAl (Cu) alloy, 400 g/m2 Ductile iron The BioZinalium® coating consists of 2 layers: A layer of zinc-aluminium 85/15 alloy, enriched with copper, with a minimum surface density of 400g/m2, applied by spraying molten metal onto the surface of the iron, using an electric arc spray gun, from ZnAl (Cu) alloy wire. A protective layer of Aquacoat® (semi-permeable) of water-based blue acrylic of average thickness of 80 microns applied using a spray gun. Saint-Gobain PAM - NATURAL® -...

Ductile iron... SAINT-GOBAIN PAM, more than 150 years of history and technical expertise Founded in 1856, SAINT-GOBAIN is the world leader in the manufacture and commercialisation of ductile iron pipeline systems. The emphasis placed on research and development has enabled the company to combine traditional know-how and technical innovation to continuously offer its customers high quality, reliable and ergonomic products. Ductile iron Ductile iron is an iron/carbon/silicon alloy containing pure carbon in a spheroidal graphite form. > Exceptional mechanical properties • Elasticity (Re ≥ 270...

Ductile cast iron benefits from the traditional longevity of cast irons with exceptional mechanical properties: elasticity of the metal, bending strength due to high elongation capacity, resistance to ovalisation, solidity and proven performance for over a century. Due to these exceptional mechanical qualities, ductile iron is suitable for all types of terrain and can withstand high stress without damage (deep or shallow depths of cover, traffic loads, other site contingencies, etc.). This explains why ductile iron and now the NATURAL® range has long been considered as the...

> In conformity with the specifications of the standard NF EN 545-2010, the pipes and fittings offer a considerable safety margin beyond the AOP (Allowable Operating Pressure): the safety coefficient is greater than 3. > In addition, the ductile iron material is not subject to any ageing and retains its mechanical strength over time. > The PFA* values of the pipes and fittings of the NATURAL® range comply with the standard NF EN 545-2010 (appendix A) and are always greater than 40 bar in sizes DN 60 to 300 and greater than 30 bar in sizes DN 350 to 600. D = diameter (mm) PFA = allowable...

3 components Optimum Service life • he material: resistance to mechanical stresses T (hydraulic pressure and ground weight), Coating Corrosion soil-water • the coatings: resistance to chemical attacks (of water and soil), Material Pressure soil burden The optimum service life is achieved when the three components - material, coatings and assemblies are perfectly reliable. • he assemblies: maintain waterproofness under all circumstances (excessive pressure or t ground movement). tightness flexibility Saint-Gobain PAM has therefore developed an original and rational approach to individually...

BioZinalium protection®... Overall corrosion protection The BioZinalium coating® retains the "active" properties of the Zinalium® coating when in contact with the ground, i.e.: • ormation of an adhesive and stable all-round protective layer (zinc hydroxides, etc.) that cover the f entire surface of the buried pipe; • estored continuity of this protective layer at points which have been slightly damaged (impacts r during transportation, scrapes when backfilling). The two-phase combination of aluminium and zinc in the ZnAl (Cu) alloy increases the strength of the overall protective layer. In...

BioZinalium protection®... Advantages of BioZinalium® The active nature of the metallic coating + the deposited surface mass + the properties of the finishing coat are the three dimensions that contribute to the efficiency of the zinc-based coating systems. oat® finish In compliance with the standards The BioZinalium® coating is in conformity with the European standard EN545: 2010 and the international standard ISO 2531. The BioZinalium coating® is suitable for the majority of soils as defined in appendix D.2.2. of the standard EN545: 2010, with the exception of: • oils located underneath...
