FAQ (Frequently Asked Questions)

How are Duplex Steel Pipes different from other types of steel pipes?

Duplex steel pipes have a two-phase microstructure consisting of both austenitic and ferritic stainless steel, providing a unique combination of properties like high strength, good weldability, and enhanced corrosion resistance compared to other steel types.

What applications are Duplex Steel Pipes commonly used for?

Duplex steel pipes are commonly used in offshore oil and gas exploration, chemical processing plants, desalination plants, petrochemical industries, and in applications where high strength and corrosion resistance are required.

How is the welding process different for Duplex Steel Pipes compared to conventional stainless steel pipes?

Welding Duplex steel pipes requires special considerations to maintain the balance between the two phases of the microstructure. Preheating, interpass temperature control, and post-weld heat treatment are often necessary to prevent issues like embrittlement and corrosion.
