NATURAL BioZinalium pipes DN80 to 300 with TYTON socket (prefered pressure classes)

• DN: nominal diameter

• Lu: laying length, in m

• Class: pressure class according to EN 545 and ISO 2531

• e: nominal thickness according to ISO 2531, in mm

• ØDE: external nominal diameter of the barrel according to EN 545 and ISO 2531, in mm

• ØDI: internal nominal diameter of the socket, in mm

• P: nominal depth of the socket, in mm

• ØB: nominal diameter of the socket, in mm

• Mass: total mass per metre (including cement coating and socket), determined with the nominal thickness, in kg/m

• Reference: commercial reference Saint-Gobain PAM

• For drinking water and other water network applications (except sewage water)

• Pressure class in conformity with Standard EN 545-2010 and ISO 2531-2009
• External BioZinalium® coating consists of two 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), a water-based blue acrylic of average thickness 80 microns applied using a spray gun (RAL 5005)
• Internal coating: sulfate resisting blast furnace cement mortar
• Tyton joint in alimentary elastomer EPDM (ACS, KTW, WRAS,…)
• Vi anchoring without bolts

BioZinalium® coating can be in contact with all type of soil, as defined in Annex D.2.2 of EN545:2010, except:

• peaty and acid soils
• soils containing wastes, scraps, ashes, slags or soils contaminated by industrial effluents or other wastes
• soils located under the level of the marine water table with a resistivity lower than 500 Ω cm

In such soils, and also in the event of stray currents, it is recommended to use other types of external coatings for more aggressive soils (TT PE or TT PUX ranges).

NATURAL^® ductile iron pipes with internal coating of sulphate resisting blast furnace cement mortar are adapted to convey all types of drinking water in conformity with Directive 98/83/CE.

In case of other type of water, please refer to below information:

Blast furnace cement mortar is a sulphate resisting cement (SRC).
