3.Features:
Facilitating high resistance to loadings, pressure and vacuum with high tensile strength,
Enabling high resistance to corrosion,
Not requiring cathodic protection,
Less operating cost since cast pipes have larger nominal diameter than polyethylene pipes.
Being the best pipe in case of an earthquake, with its ability of resilience and resistance to impacts without deformation,
Long product life, exceeding 50 years,
Preserving the quality of water with healthy interior coating.
