Ductile iron pipes for highly aggressive soils

All Terrain or TT (“Tous Terrain”) ductile iron pipes are protected by an exterior coating that is suitable for extremely corrosive soil in which a zinc coating is no longer sufficient.

The pipes come in two types according to the diameter - PE or PUX:

  • For diameters between 80 and 700 mm: TT PE pipes, coated with a 2 mm layer of extruded polyethylene over an undercoat of zinc (conforming to standard EN 14628)

  • For diameters between 800 and 2000 mm: TT PUX pipes, coated with a 1 mm layer of polyurethane thermally sprayed onto shot-blasted ductile cast iron (conforming to standard EN 15189)

The fittings for these pipes have a thick epoxy external coating for the small diameters and a polyurethane coating for the larger ones. The range of application of coatings is specified in Annex D of standard EN 545.


Saint­-Gobain PAM's technical teams can conduct soil surveys as per the customers’ request.

 
DN : 80 to 2000
