Key Advantages
Exceptional Strength - Higher tensile strength (≥500 MPa) and impact resistance than traditional cast iron.
Corrosion Protection - Optional epoxy/zinc coatings for harsh environments (e.g., seawater, acidic soils).
Leak-Free Performance - Precision-machined joints ensure tight sealing (tested to 1.5x working pressure).
Cost-Effective - 30% lighter than gray iron fittings, reducing transport/installation costs.
Eco-Friendly - 100% recyclable material with low carbon footprint.
Applications
Water & Wastewater: Municipal water supply, drainage, and sewage treatment plants.
Industrial: Chemical processing, mining slurry pipelines, and fire protection systems.
Infrastructure: HVAC systems, underground cable conduits, and bridge drainage.
