Manufacturing Process & Heat Treatment of Duplex Pipes
Annealing
The annealing process for duplex pipes involves heating the material to a temperature range of 1020°C to 1100°C, followed by a controlled cooling process. This treatment helps to relieve internal stresses, enhance ductility, and improve the overall mechanical properties of the duplex stainless steel.
Forging
Forging of duplex pipes is conducted at elevated temperatures, typically between 1050°C and 1200°C. This process improves the strength and structural integrity of the material by refining the grain structure, resulting in enhanced performance in demanding applications.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1000 - 1100 | Water or Oil | Increase hardness and strength |
| Tempering | 300 - 600 | Air | Reduce brittleness and improve toughness |
| Stress Relieving | 600 - 700 | Air | Eliminate residual stresses |
The combination of these processes ensures that duplex pipes meet the stringent requirements for strength, corrosion resistance, and durability in various industrial applications, making them suitable for global exports.
