Manufacturing Process & Heat Treatment of Duplex Pipes
Annealing
The annealing process for duplex pipes involves heating the material to a temperature range of 950-1100°C and holding it for a specified duration. This process helps to relieve internal stresses, improve ductility, and enhance the overall microstructure of the steel, ensuring optimal performance in various applications.
Forging
Forging of duplex pipes is conducted at elevated temperatures ranging from 1050-1200°C. This process involves shaping the metal through compressive forces, which refines the grain structure and enhances mechanical properties such as strength and toughness. The resulting forged pipes exhibit improved resistance to stress corrosion cracking.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1020-1100 | Oil | Increase hardness and strength |
| Tempering | 600-800 | Air | Reduce brittleness and improve toughness |
| Stress Relieving | 550-650 | Air | Minimize residual stresses |
The combination of these heat treatment processes ensures that duplex pipes achieve the desired mechanical properties, durability, and resistance to corrosion, making them suitable for a wide range of industrial applications.
