What is a duplex steel heat exchanger tube, and what are its
advantages?
A
duplex steel heat exchanger tube
refers to a type of tube used in heat exchangers that is made
from duplex stainless steel. Duplex stainless steel is a highly
corrosion-resistant material that combines austenitic and
ferritic stainless steel benefits. It is characterized by its
high strength, excellent resistance to pitting and crevice
corrosion, and good weldability.
The advantages of using duplex steel heat exchanger tubes are manifold. Their superior corrosion resistance makes them ideal for applications in aggressive environments, such as chemical processing plants or marine environments, where exposure to corrosive fluids or seawater is common. Duplex steel offers high mechanical strength, which enables the tubes to withstand high pressures and temperatures, making them suitable for demanding industrial processes.

Their weldability allows easy fabrication and installation, reducing production time and costs. Duplex steel heat exchanger tubes exhibit excellent resistance to stress corrosion cracking, enhancing reliability and durability in harsh operating conditions. The combination of corrosion resistance, mechanical strength, weldability, and resistance to stress corrosion cracking makes duplex steel heat exchanger tubes a preferred choice for industries requiring efficient heat transfer with long-term reliability.
How does the duplex steel used in heat exchanger tubes differ
from other types of steel?
The duplex steel used in heat exchanger tubes differs from other
types of steel primarily in its microstructure and composition.
Unlike conventional steels, which consist solely of austenite or
ferrite, duplex steel is a dual-phase alloy containing both
phases in roughly equal proportions. This unique microstructure
is achieved by carefully controlling the amounts of
austenite-forming elements (nickel, nitrogen, and manganese) and
ferrite-forming elements (such as chromium and molybdenum)
during the steelmaking process.
The presence of both austenite and ferrite phases imparts distinctive properties to duplex steel. It combines the corrosion resistance and toughness of austenitic stainless steel with the high strength and resistance to stress corrosion cracking exhibited by ferritic stainless steel. This results in a material that offers an excellent balance of mechanical strength and corrosion resistance, making it well-suited for demanding applications such as heat exchangers.

Drawing/ Floating Process
Pulling a metal bar, rod, or wire through the entirety of a die to change its finish, shape, size, and/or mechanical qualities is known as floating or drawing. The tube's outer, inner, and wall thicknesses are all reduced via the tube drawing procedure. Stainless steel tubes benefit from maintaining the integrity of their surface.
Continuous Heat Exchanger Tube Mills
The production of Heat Exchanger tubes has been transformed by continuous tube mills. These mills do away with the necessity for forging welding or filler metal, in contrast to conventional procedures. With the use of this technology, Heat Exchanger pipes and tubes may be produced continuously, increasing productivity while lowering costs and improving efficiency.
Continuous Casting
A notable advancement in the production of Heat Exchanger tubes is continuous casting. The metal is solidified into a continuous billet through the continuous pouring of molten metal into a water-cooled mould. Better uniformity and enhanced mechanical qualities are guaranteed by this continuous casting technique for the tubes.
Annealing
Metal is heated above the point of re-crystallization and cooled to room temperature during the annealing process. The molecular bonds in metal tighten when it is shaped, making it rigid. The metal is put through an annealing process to regain its ductility.
Sinking Process
Tube sinking is a drawing technique that reduces the diameter of tubes. In this drawing technique, a tube is run through a die without the need of a mandrel. Good inner surface quality is not ensured when using a mandrel. The die angel determines the integrity of the outer surface. The die being used produces a uniform surface. A tube can be significantly smaller than it was originally. When cost is a factor, tube sinking is ideal.
Inspection and Testing
Before sending our items to our consumers, we conduct inspection procedures to verify their integrity.
