Cast Iron Pipes
Cast iron pipes provide exceptional durability and service life in municipal water and sewage applications. The material’s inherent corrosion resistance improves with formation of protective internal oxide layers during service.
Cast iron’s thermal mass and damping characteristics minimize vibration and noise transmission in pressure systems. The material’s strength enables pressure ratings comparable to steel with simpler manufacturing processes.
Specifications
- Standard diameter range from 3″ to 24″ for main applications
- Pressure ratings from 150 to 300 PSI depending on thickness
- Ductile iron provides improved impact resistance over gray iron
- Standard bell-and-spigot or mechanical joint connections
Applications
- Municipal water supply main distribution lines
- Sewage and wastewater force main installations
- Industrial cooling water circulation systems
- Fire protection system underground mains
Benefits
- Service life exceeding 50 years in normal conditions
- Inherent corrosion resistance improves with age as oxide layer develops
- Superior damping reduces water hammer and vibration noise
- Cost-effective material for large-diameter applications
