Manufacturing Process & Heat Treatment of Duplex Pipes
Annealing
Annealing of duplex pipes involves heating the material to a temperature range of 1020°C to 1100°C, followed by controlled cooling. This process helps to relieve internal stresses and improve ductility, ensuring optimal mechanical properties for further processing and applications.
Forging
Forging of duplex pipes is conducted at elevated temperatures between 1000°C and 1200°C. This process enhances the material's strength by refining the grain structure and improving its overall mechanical performance. Forged duplex pipes exhibit superior toughness and resistance to corrosion.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1050 - 1150 | Water or Oil | Increase hardness and strength of the material. |
| Tempering | 400 - 600 | Air | Reduce brittleness while maintaining hardness. |
| Stabilization | 800 - 900 | Air | Enhance corrosion resistance and stabilize microstructure. |
The manufacturing and heat treatment processes of duplex pipes are crucial for achieving the desired mechanical properties and ensuring performance in demanding applications. These processes contribute to the durability and reliability of the final product.
