- ASTM A789 – Standard specification for seamless and welded ferritic/austenitic stainless steel tubes.
Equivalent Grades of Super Duplex Steel Pipes
- UNS S32750
- UNS S32760
- SAF 2507
- 1.4410
These equivalent grades are designed to offer similar mechanical properties, corrosion resistance, and high strength. They are ideal for use in various demanding environments, such as in the oil and gas, chemical processing, and marine industries.
Manufacturing Process of Super Duplex Steel Pipes
- Rolling and Welding
The process begins with strips passing through rollers to achieve the required size. These strips are then shaped into tubes, and a welding machine is used to join the edges using the TIG welding process. - Length Cutting
Once the pipes are formed, they are cut to the required lengths using a variety of methods, such as sawing, lathe cutting, and laser cutting. - Cleaning and Heating Phase
The pipes undergo cleaning to remove any contaminants. Following this, heat treatment is applied to relieve stress caused by welding and forming processes. - Cold Drawing Process
If the required size is not achieved in the initial rolling process, cold drawing is employed. This process involves drawing the pipe over a die to achieve the desired size and finish. - Finishing Process
Finally, the pipes undergo pickling, heat treatment, and straightening. The finished products are then marked with the grade, size, and heat number using a computerized ink-jet marking machine.
Chemical Composition of Super Duplex Steel Pipes
Super Duplex Steel pipes are made from a mixture of chromium, nickel, molybdenum, and nitrogen in precise proportions. A typical composition may include:
- Chromium: 25%
- Nickel: 7%
- Molybdenum: 3%
- Nitrogen: 0.25%
This specific combination of elements gives Super Duplex Steel its impressive corrosion resistance, high strength, and excellent weldability.
Mechanical Properties of Super Duplex Steel Pipes
Super Duplex Steel pipes exhibit outstanding mechanical properties, making them ideal for demanding applications. These properties include:
- High tensile strength
- Excellent resistance to corrosion
- Superior toughness, even at low temperatures
Thanks to the unique combination of austenitic and ferritic stainless steels, these pipes are highly versatile and perform well in applications across industries like oil and gas, chemical processing, marine engineering, and more.
