Main characteristics:

Joint in alimentary elastomer EPDM (ACS, KTW, WRAS,…)
External coating: 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 + cement mortar ZMU with polymeric additiv and reinforced with PE fibers
Internal coating: sulfate resisting blast furnace cement mortar
ZMU pipes in accordance with EN 545
ZMU coating according to EN 15542

Field of use:

Drinking water networks

Type of soils:

ZMU coating can be in contact with nearly all types of soil. Please consider the following matrix based upon resistivity of soils. In case of doubt, please advise.

Type of water:

Ductile iron pipes with internal coating of sulphate resisting blast furnace cement mortar (SRC) 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 to check the compatibility with cement mortar.
