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 and then cooling it slowly in air. This process helps to relieve internal stresses, enhance ductility, and improve corrosion resistance, making it suitable for various industrial applications.
Forging
Forging of Duplex 2304 involves shaping the material through compressive forces at elevated temperatures, typically between 950°C and 1150°C. This method improves mechanical properties by refining the grain structure and ensuring uniformity in the material, which is critical for high-strength applications.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1000 - 1100 | Oil | Increase hardness and strength |
| Tempering | 600 - 800 | Air | Reduce brittleness and improve toughness |
| Solution Treatment | 1020 - 1100 | Water | Enhance corrosion resistance and mechanical properties |
The combination of these processes ensures that Duplex 2304 EFW pipes meet the stringent requirements for strength, durability, and resistance to corrosion, making them ideal for various applications in the oil and gas, chemical, and marine industries.
