Super Duplex Steel S32950 Seamless Pipes Manufacturing Process

Manufacturing ASME SA790 super duplex pipes follows a structured five main steps which is outlined below.
Super Duplex Steel Seamless Pipes Manufacturing Process

1. Raw Material Selection

High-quality super duplex stainless steel billets and strips are carefully selected for superior strength and corrosion resistance.

2. Pipes Formation
The selected raw material is formed into pipes using seamless extrusion methods, depending on the application.

3. Heat Treatment
Pipes undergo required controlled heat treatment to enhance mechanical properties and relieve internal stresses.

4. Cold Working & Finishing
After heat treatment, pipes are cold-worked for better surface finish, dimensional accuracy and improved strength.

5. Quality Control and Testing
Every pipe is thoroughly inspected and tested to ensure it meets international quality standards for performance and reliability.
