Manufacturing Process & Heat Treatment of Duplex 2304 EFW Pipe
Annealing
The annealing process for Duplex 2304 EFW pipes involves heating the material to a temperature range of 1020°C to 1100°C. This process helps to relieve internal stresses, improve ductility, and enhance overall mechanical properties. After reaching the desired temperature, the pipes are cooled in still air to ensure a homogeneous microstructure.
Forging
Forging of Duplex 2304 involves shaping the material at elevated temperatures, typically between 800°C and 1200°C. This process enhances the mechanical properties of the steel by refining the grain structure and improving strength and toughness. The forged pipes are then subjected to controlled cooling to preserve their enhanced characteristics.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1000 - 1100 | Water | To increase hardness and strength |
| Tempering | 600 - 800 | Air | To reduce brittleness and improve toughness |
| Stress Relieving | 300 - 500 | Air | To relieve internal stresses after welding |
The combination of these processes ensures that Duplex 2304 EFW pipes meet the stringent requirements for strength, corrosion resistance, and durability, making them suitable for various industrial applications.
