• 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

• c: weld bead position, in mm

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

• Reference: commercial reference Saint-Gobain PAM

• Aggressive or soft waters

• Pressure class in conformity with Standard EN 545-2010 and ISO 2531-2009
• External Zinalium 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: 800 microns mini thick layer of sand-coloured polyurethane
• Standard joint in alimentary elastomer EPDM (ACS, KTW, WRAS,…)

^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).
