Main characteristics:

Pressure class in conformity with Standard EN 545-2010 and ISO 2531-2009
External coating with 2 barriers, in accordance with EN14628-1:2020 (option PE-G): - Back barrier: a metallic layer of ZnAl(Cu) 85/15 alloy (mini surface density 400 g/m²) applied by spraying molten metal on to the surface of the ductile iron + finishing acrylic layer (Aquacoat) - Front barrier: a continuous thick organic layer of extruded PE + hot melt adhesive layer applied on the back barrier, standard thickness according to DN (table 2 of EN14628-1)
Internal coating: sulfate resisting blast furnace cement mortar
EPDM rubber gasket suitable for contact with drinking water (ACS, KTW, WRAS,…)
Restraining possible with STD Vi joint (without bolts)

Soils characteristics: Ductile iron pipes coated with TT PE may be buried in contact with a large number of soils, normal and highly corrosive soils (low resistivity soil, mixed soils, polluted soils...), also in soils with occurrence of stray currents. Please refer to the informative annex D of EN545.
Water characteristics: Ductile iron pipelines supplied with lining sulfate resisting blast furnace cement mortar may be used to convey all types of water intended for human consumption in conformity with the Directive 98/83/EC. For other types of water, the limits of use are as given in below Table. Please refer to the informative annex E of EN545. Minimum value Maximum value Parameter pH CO2 aggressive Sulphate Magnesium Ammonium Unit - mg/l mg/l mg/l mg/l Value 5,5 15 3000 500 30
