Material & Manufacturing
DN80mm ductile iron pipes are crafted from high-strength ductile iron (Grade 450-12), featuring 3% carbon content and nodular graphite microstructure for exceptional:
-
Tensile strength: ≥420 MPa.
-
Impact resistance: 12 Joules at -20°C.
-
Corrosion protection: Cement mortar lining + zinc-aluminum coating (ISO 8179 standard).
Applications
Ideal for high-pressure and corrosive environments:
✅ Potable water distribution (e.g., municipal networks in EU/ASEAN).
✅ Wastewater treatment plants (acid-resistant lining options available).
✅ Industrial pipelines (oil/gas, mining slurry transport).
✅ Fire protection systems (tested to BS EN 10255:2004).
