FIELD OF APPLICATION

 

The ductile iron pipes “AQUA” are suitable for conveying all kinds of potable water in compliance with the Directive 98/83/EC, in case of other types of water the main limitations of use are described in the following table:

The “AQUA” pipes can be buried in all kinds of soils, except in acid peaty soils, soils containing waste, ash, slag or polluted by industrial wastes or effluents, soils located below the marine groundwater with resistivity less than 500 Ohm*cm. In these soils and also in presence of stray currents, it’s recommended to use other types of coatings for soils of higher aggressiveness according to EN 545:2010.

MAIN TECHNICAL FEATURES

 

Pressure class in accordance with EN 545:2010 and ISO 2531:2009.

 

External coating in zinc- aluminum alloy (400 g/m2) applied by metallization and watery epoxy paint certified to be in contact with water intended for human use.

 

Internal lining in cement mortar blast furnace sulfate-resistant in accordance with EN 545 and ISO 4179

 

Automatic flexible joint in compliance with UNI 9163 or DIN 28603 with EPDM elastomer gasket, certified to be in contact with water intended for human use, conforming to EN 681-1.

 

 

COMPETITIVE ADVANTAGES

 

Quick and safe installation thanks to the automatic flexible joint

 

Fast execution of the installation and possibility of reducing the number of fittings, even in the case of land with irregular elevation course, due to the high angular deviation

 

Excellent behavior in case of earthquake

 

Low roughness that determines minimum pressure losses

 

Resistance to corrosion by corrosive waters

 

Resistance to corrosion by aggressive soils in most of the cases
