Duplex Steel Pipes & Its Application

Duplex steel pipes are a popular choice for various industrial applications due to their unique combination of high strength, excellent corrosion resistance, and good weldability. They are used in industries such as oil and gas, chemical processing, and marine engineering, among others. In this blog, we will discuss duplex steel pipes and the grades of duplex steel pipes in the UNS standard.

Duplex Steel Pipes


What is Duplex Steel?

Duplex steel is a type of stainless steel that contains a two-phase microstructure consisting of both austenitic and ferritic grains. This unique microstructure provides duplex steel with excellent corrosion resistance, high strength, and good weldability. Duplex steel is commonly used in environments where conventional austenitic stainless steels would be prone to stress corrosion cracking and pitting corrosion.

What are Duplex Steel Pipes?

Duplex steel pipes are pipes made from duplex steel. They are available in a variety of sizes and dimensions and are commonly used for transporting fluids and gases in corrosive environments. Duplex steel pipes can withstand high temperatures and pressures and are known for their excellent resistance to corrosion and erosion.

What are Duplex Steel Seamless Pipe ?

Duplex steel seamless pipes are a type of duplex stainless steel pipe that are manufactured without any welding or joints. These pipes are created by piercing a solid billet of duplex stainless steel and then rolling it into a seamless pipe.

What are Duplex Steel ERW Pipe?

Duplex steel ERW (Electric Resistance Welded) pipes are made from duplex stainless steel material through the process of forming and welding. These pipes are produced using a high-frequency electrical current to create a weld between the edges of the steel strip or coil. The welding process used to manufacture ERW pipes makes them more cost-effective than seamless pipes.

What are Duplex Steel Welded Pipe?

Duplex steel welded pipes are made by joining two pieces of duplex steel using different welding techniques such as TIG, MIG, or submerged arc welding. These pipes have a welded seam running along their length and are available in various sizes and thicknesses.

Grades of Duplex Steel Pipes in UNS Standard
