What is duplex steel, and why is it used in boiler tubes?

Duplex Steel is a type of stainless steel that contains a balanced microstructure of austenite and ferrite phases. This unique combination of phases gives duplex steel desirable properties, making it an ideal material for various applications, including boiler tubes. Austenite and ferrite phases in duplex steel provide exceptional strength, corrosion resistance, and toughness.

These characteristics make it highly suitable for boiler tubes exposed to high temperatures, pressure, and corrosive environments. Duplex steel's ability to withstand harsh operating conditions helps ensure boiler systems' longevity and reliability while minimizing the risk of corrosion-related failures. Additionally, the high mechanical strength of duplex steel allows for thinner tube walls, resulting in more efficient heat transfer and improved energy efficiency in boiler applications.

What are the advantages of duplex steel boiler tubes compared to other materials?

Using duplex steel boiler tubes offers several advantages over other materials. Duplex steel exhibits excellent corrosion resistance, especially in aggressive environments containing chlorides and acids. This superior corrosion resistance minimizes the risk of tube failures and extends the operational lifespan of the boiler system. Duplex steel possesses high mechanical strength, allowing for the design of thinner tube walls without compromising structural integrity.

This results in improved heat transfer efficiency and energy savings. Moreover, duplex steel maintains its mechanical properties at elevated temperatures, ensuring the stability and reliability of the boiler tubes under demanding operating conditions. Additionally, duplex steel's dual-phase microstructure provides a good combination of toughness and flexibility, enhancing the resistance to stress corrosion cracking and reducing the likelihood of tube rupture. Duplex steel is readily available in the market and has well-established fabrication and welding techniques, making it a practical and cost-effective choice for boiler tube applications.

Duplex Steel Boiler Tube Manufacturing Process

Welding Process

The grade and application requirements have an impact on tube welding and forming. For the manufacturing of tiny diameter tubes, we employ TIG welding. Steel sheets are coiled and welded inside of a welding machine. The steel sheets are shaped into a coil before entering the machine. The seam between these coils is then welded to create a Tube.

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 Seamless Tube Mills

The production of seamless 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, seamless pipes and tubes may be produced continuously, increasing productivity while lowering costs and improving efficiency.

Continuous Casting

A notable advancement in the production of seamless 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.
