What is a super duplex pipe?

Super duplex stainless steel is the third-generation combination of austenitic and ferrite alloys. With higher chromium composition of over 25%, the PREN or pitting resistance equivalent number of super duplex alloy will be over 40. Hence it applies in many demanding applications like offshore oil & gas, the food & beverage industry, etc.

Super Duplex pipe has high corrosion resistance as it is made from super duplex steel to have additional properties. Though expensive because of its higher nickel content finds use in many more applications. It includes heat exchangers, cargo tanks, rotors, shafts, hydraulic lines, etc.

Super Duplex Pipe Properties

Super duplex vs. duplex

Duplex and super duplex are part of the stainless steel family with higher corrosion resistance and strength. The highly demanding industrial applications involving high chlorine and temperature needed more potent stainless steel. The duplex was the second generation of stainless steel with added chromium, nickel, and molybdenum. Super duplex is the third generation with the same content but with increased quantity. Hence there are a few differences between the two, including the following among others.

  • A Super duplex is higher in strength than a duplex.
  • Super duplex is more corrosion resistant than duplex
  • Super duplex is more expensive than duplex

Do you need a super duplex steel pipe in a seamless or welded form in a specific size from a reliable stockist in the Middle East or Africa? Your search is over here. Look at the material grades.

What are super duplex stainless steel pipe material grades?

There are over 3500 grades of steel to identify the composition for specific uses. Also, the many super duplex stainless steel pipe material grades depend on their chromium, nickel, and molybdenum composition. The prestigious standard organizations ASTM and ASME or SAE approve many of them for specific uses in many industries. They also support many grades for pipes, welded, seamless, welded, welded, etc.

The super duplex steel pipe grades include 2507 with a high chromium content of 28% and 4501duplex pipes. As per the grades, the duplex pipes find use in seawater systems, umbilicals, desalination plants, flue-gas cleaning, pressure vessels, tanks, and others.

What are the benefits of the super duplex steel pipe?

The super duplex pipe has many benefits for many sectors to use in diverse applications. A few benefits of its include the following, among others.

  • High strength, thermal conductivity, heat conductivity, and energy absorption
  • Low coefficient of thermal expansion
  • Excellent resistance to erosion, corrosion fatigue, and stress corrosion cracking
  • High resistance crevice and pitting corrosion resistance
  • Good weldability, workability, and sulfide stress corrosion resistance
  • Pipes made of super duplex steel having the above top properties are best for making power energy FGD systems, heat exchangers, mechanical and structural components, etc.

Which cutting method is best to cut super duplex seamless pipe?

Super duplex pipe though harder than pipes made of many other stainless steel grades, can be cut using specific methods. The high strength and elongation combination of super duplex steel makes breaking its chips difficult, as it will affect the surface finish negatively. Also, it is critical to cut it without affecting the mechanical strength and corrosion resistance properties.

So the best method to cut pipes made of the super duplex is laser cutting because it provides excellent tolerance and surface quality. Since laser has no problem with high strength, selective laser melting is fast emerging as the additive process to get near-net shape manufacturing solutions for super duplex steel pipes and pipes.

What is SDSS material?

During the late 1960s, the second-generation duplex steels evolved to super duplex stainless steel called SDSS. Though with the same elements like chromium, nickel, and molybdenum, the quantity of the SDSS material increased to provide high strength and corrosion resistance. Many SDSS material-made pipes are available in different sizes, shapes, wall thicknesses, and others.

The super duplex welded pipe is one of them to be useful in many applications. Also, the super duplex welded pipe are the best in medical and other sectors. The top super duplex pipe suppliers offer many other pipes made of SDSS material at competitive costs.
