What is a Duplex Stainless Steel Pipe?

Duplex stainless steels are called “duplex” because they have a two-phase microstructure consisting of grains of ferritic and austenitic stainless steel. The picture shows the yellow austenitic phase as “islands” surrounded by the blue ferritic phase. When duplex stainless steel is melted it solidifies from the liquid phase to a completely ferritic structure. 2205 duplex stainless steel is a cost effective solution for many applications where the 300 series stainless steels are susceptible to chloride stress corrosion cracking. Stress corrosion cracking occurs when stainless steels are subjected to tensile stress, while in contact with solutions containing chlorides. Increasing temperatures also increase the susceptibility of stainless steels to stress corrosion cracking.

Inspection & Testing of Duplex Stainless Steel Pipes

  • Mechanical Testing Such as Tensile of Area, Hardness Test, Positive Material Identification – PMI Testing, Flattening Test, Micro and Macro Test, Pitting Resistance Test, Flaring Test, Intergranular Corrosion (IGC) Test.

Metline is a large producer of various type of duplex stainless steel pipes such as seamless pipes, welded pipes, ERW pipes types. We produce and forge duplex stainless steel pipes to specifications of ASTM A249, ASTM A269, ASTM A213, ASTM A312, ASTM A790. Duplex steels are easily welded and formed, similar to austenitic grades. Depending on chromium, nickel and molybdenum content, duplex stainless steels are divided into four main categories: lean duplex, duplex, super duplex and hyper duplex.

Features of Duplex Stainless Steel Pipes

  • Durable
  • High strength
  • Excellent finish
  • Dimensional accuracy
  • High energy absorption.
  • High energy absorption.
  • Good workability and weldability
  • Good sulfide stress corrosion resistance
  • High resistance to pitting, crevice corrosion resistance
  • Low thermal expansion and higher heat conductivity than austenitic steels.

Metline Industries is one of the prominent supplier, manufacturer and exporter of duplex stainless steel pipes which have only moderate resistance to carbon absorption and are not suggested for its usage in highly carburizing atmospheres. Our manufacturing process for duplex stainless steel pipes includes an adequate heat treatment and the examination of chemical and mechanical properties. We have CNC machines as well as conventional lathe machines for machining and processing various types of duplex stainless steel pipes.
