Cement-lined ductile iron pipe fittings are engineered for durability and performance in demanding fluid transport systems. Combining the strength of ductile iron with a protective cement mortar lining, these fittings excel in water supply, wastewater management, fire protection, and industrial applications.
Applications
Cement-lined ductile iron fittings are ideal for:
- Potable Water Distribution: Safeguards water quality by preventing corrosion and scaling.
- Fire Suppression Systems: Ensures reliable pressure resistance for emergency infrastructure.
- Wastewater and Sewage Systems: Resists chemical degradation in aggressive environments.
- Industrial Pipelines: Suitable for slurry transport, cooling systems, and chemical processing.
Pressure Ratings and International Standards
Pressure Classes:
- Standard pressure ratings range from Class 150 (PN10) to Class 350 (PN35), accommodating pressures up to 350 psi (24 bar).
- Customizable designs available for high-pressure industrial requirements.
Compliance with Global Standards:
- ISO 2531: Specifies dimensions, pressure ratings, and cement lining requirements.
- EN 545/EN 598: European standards for water/wastewater applications.
- AWWA C104/C110: American Water Works Association guidelines for lining and joint integrity.
- BS 4772: British standards for ductile iron fittings in fire hydrant systems.
Key Advantages
- Corrosion Resistance:
- The cement lining acts as a pH-neutral barrier, protecting against electrochemical and microbial corrosion.
- Outperforms unlined ductile iron or steel fittings in longevity (50+ years with proper maintenance).
- Hydraulic Efficiency:
- Smooth interior surface minimizes friction loss, reducing pump energy costs by up to 15% compared to corroded pipes.
- Mechanical Strength:
- Ductile iron’s tensile strength (≥420 MPa) and impact resistance ensure structural integrity under ground movement or heavy loads.
- Cost-Effectiveness:
- Lower lifecycle costs due to minimal maintenance and replacement needs.
- Environmental Sustainability:
- Fully recyclable material aligns with green construction practices.
Price Comparison with Alternative Materials
| Material | Initial Cost | Lifespan | Maintenance Cost | Best Use Case |
|---|---|---|---|---|
| Cement-Lined DI | Moderate | 50+ years | Low | Long-term water infrastructure |
| PVC/CPVC | Low | 25–40 years | Very low | Low-pressure residential |
| Carbon Steel | High | 20–30 years | High | High-temperature industrial |
| Stainless Steel | Very High | 40+ years | Moderate | Chemical processing |
Note: Cement-lined ductile iron offers the optimal balance of durability and affordability for municipal and industrial projects.
