What are the different types of Duplex Steel Tubes?

Duplex Steel Tubes are a type of steel pipe that is made from a combination of ferritic and austenitic stainless steels. This gives them a unique combination of strength, corrosion resistance, and toughness.

Duplex Steel Tubes offer a number of benefits over other types of steel pipe, including: * Higher strength: Duplex Steel Tubes are stronger than other types of steel pipe, making them ideal for use in applications where high strength is required. * Greater corrosion resistance: Duplex Steel Tubes have a higher corrosion resistance than other types of steel pipe, making them ideal for use in applications where corrosion is a concern. * Improved toughness: Duplex Steel Tubes are tougher than other types of steel pipe, making them more resistant to damage.

Duplex Steel Tubes are used in a wide variety of applications, including: * Chemical processing: Duplex Steel Tubes are used in chemical processing plants to transport corrosive chemicals. * Oil and gas production: Duplex Steel Tubes are used in oil and gas production to transport oil and gas. * Marine applications: Duplex Steel Tubes are used in marine applications to transport seawater and other corrosive fluids. * Power generation: Duplex Steel Tubes are used in power generation plants to transport steam and other hot fluids.

Duplex Steel Tubes are manufactured using a variety of processes, including: * Hot rolling: Duplex Steel Tubes are hot rolled to form the desired shape and size. * Cold rolling: Duplex Steel Tubes are cold rolled to improve their surface finish and dimensional accuracy. * Welding: Duplex Steel Tubes can be welded to create longer lengths or to connect them to other components. * Heat treatment: Duplex Steel Tubes are heat treated to improve their mechanical properties.

There are a number of different types of Duplex Steel Tubes available, including: * Seamless Duplex Steel Tubes: Seamless Duplex Steel Tubes are made from a single piece of steel, which gives them a smooth, uniform surface. * Welded Duplex Steel Tubes: Welded Duplex Steel Tubes are made from two or more pieces of steel that are welded together. Welded Duplex Steel Tubes are typically less expensive than seamless Duplex Steel Tubes, but they may have a slightly lower strength. * Duplex Steel Tubes with Special Coatings: Duplex Steel Tubes can be coated with a variety of materials to improve their corrosion resistance or other properties.

Duplex Steel Tubes are made of duplex stainless steel which is a unique structure because of the inclusion of austenite and ferrite phases. This metallurgical structure of it is beneficial in providing great strength, toughness, hardness and excellent corrosion resistance, especially chloride pitting and stress cracking corrosion resistance. It has twice the yield strength of their counterparts i.e., austenitic stainless steel and mild steel. 

The chemical composition of Duplex Steel Tubes is 20-28% Chromium (Cr), up to 5% higher Molybdenum (Mo), up to 9% Nickel (Ni), and 0.05-0.50% Nitrogen (N). The structural property of the tube remain stable at high working temperatures which make it ideal for a vast range of applications, such as tubes used in oil and gas industry, chemical industry, pharmaceuticals, industrial plants and others. 

The main difference between stainless steel and duplex steel tubes lies in their chemical compositions. The duplex has higher chromium (Cr) content up to 25% and molybdenum content than that of stainless steel which contains only 11% chromium and lower molybdenum. The higher the Cr content, the higher yield strength; makes duplex steel more efficient, reliable and durable.

FAQs Related to Duplex Steel Tubes

Duplex steel has higher chromium (Cr) content up to 25%, while stainless steel has lower Cr content i.e., only 11%. Due to difference in their chemical compositions, duplex steel has twice the yield strength and corrosion resistance than stainless steel (SS).

•Excellent corrosion resistance, chloride pitting and stress cracking resistance 
•Twice yield strength than stainless steel 
•Heat resistance over 300°C
•Toughness and ductility 
•Weldability 
Super duplex steel has higher chromium content up to 32% which is much more than duplex steel tubes having about 25% Cr content. This makes super duplex more tough and corrosion resistant and duplex steel.

Seamless duplex steel tubes, welded tubes, fabricated tubes and ERW duplex steel tubes are the common types. Different grades of duplex steel also define types.
