What is Duplex Steel Pipe?

Duplex Steel Pipe is used in various industrial applications and has proven to be a reliable material. The material is especially beneficial for structural applications. This is because it can resist intergranular and crevice corrosion, which are common problems with other stainless steel types. It also exhibits good resistance to stress corrosion cracking, even when used at temperatures as high as 300 degrees.

Because of these advantages, the use of Duplex Steel Pipe has increased significantly. They can resist pitting and crevice corrosion and have better strength than austenitic grades. Additionally, they are more resistant to stress corrosion cracking than austenitic grades, making them ideal for high-stress environments. Duplex is less expensive than other stainless steel, which is why more and more companies are using it.

Uses and Advantages of Duplex Steel Pipe

Many industries use duplex stainless steel pipes, including the medical, food, oil, gas, and chemical industries. They are used for several reasons, such as their excellent corrosion resistance and strength, which allows them to withstand high chlorine exposure. Since they can withstand various stresses, they are suitable for pressure vessels. Furthermore, they are not as brittle as other types of stainless steel, which is important for pressure vessels.

Depending on the application, duplex stainless steel can be produced in several different diameters and styles. Typical applications include ducting, piping, firefighting, and injection and ballast water systems. The tensile strength of these pipes can be very high. Therefore, these piping systems are very efficient.
