Main characteristics:

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
Pressure class in conformity with Standard EN 545-2010 and ISO 2531-2009
Standard joint in alimentary elastomer EPDM (ACS, KTW, WRAS,…)

For specific soils (maritime, acid, polluted, isolated current)
For drinking water networks
High durability
Total compatibility with drinking water
Joint protection with elastomer sleeve and HDD metal cone
Adapted to the trenchless pipe laying in rocky soils (horizontal directional drilling and pipe bursting)

Type of water:

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.
