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, followed by a controlled cooling process. This treatment helps to relieve internal stresses, enhance ductility, and improve corrosion resistance by promoting a more uniform microstructure.

Forging

Forging of Duplex 2304 involves shaping the material at elevated temperatures, typically between 900°C and 1200°C. This process enhances the mechanical properties of the steel through deformation, resulting in improved strength and toughness. The forged pipes are then cooled gradually to maintain their structural integrity.

Hardening & Tempering

Process Temperature Range (°C) Quenching Medium Purpose
Hardening 1000 - 1100 Oil or Water Increase hardness and strength
Tempering 600 - 800 Air Reduce brittleness and improve toughness
Stress Relieving 500 - 600 Air Reduce residual stresses from welding and forming

The manufacturing and heat treatment processes for Duplex 2304 EFW pipes are critical to ensuring that the final products meet the stringent requirements for strength, durability, and corrosion resistance, making them suitable for a wide range of industrial applications.
