Advantages
Better Mechanical Properties:
Microstructure comparison for Ductile Iron, Steel and Grey Cast Iron,
Better mechanical properties than steel pipe and grey cast iron pipe (as following table),
Type of Pipe | Mechanical Properties |
Tensile Strength | Elongation(%) | Hardness(HB) |
Ductile Iron Pipe | ≥420N/mm2 | (DN≤1000)≥10 (DN>1000)≥7 | ≤230 |
|
|
Grey Cast Iron Pipe | 150-260N/mm2 | Negligible | ≤230 |
|
Steel Pipe | ≥400N/mm2 | ≥18 | Approx.140 |
|
