Duplex

Chemipetro Limited offers a large variety of products in Duplex Stainless Steel alloys such as tubing, seamless- and welded pipe, butt weld fittings, flanges, pressure fittings and fasteners:

Called duplex because of its mixed microstructure with about equal proportions of ferrite and and austenite, duplex stainless steels are a family of grades, which range in corrosion performance depending on their alloy content.

BENEFITS OF DUPLEX STAINLESS STEEL

  • High strength
  • A cost-effective alternative to austenitic stainless steel 316L.
  • High resistance to pitting, crevice corrosion resistance
  • High resistance to stress corrosion cracking, corrosion fatigue and erosion,
  • Good sulfide stress corrosion resistance,
  • Low thermal expansion and higher heat conductivity than austenitic steels,
  • Good workability and weldability,
  • High energy absorption.

DUPLEX STAINLESS STEEL APPLICATIONS

  • Heat exchangers, tubes and pipes for production and handling of gas and oil,
  • Heat exchangers and pipes in desalination plants,
  • Pressure vessels, pipes, tanks and heat exchangers for processing and transport of various chemicals,
  • Pressure vessels, tanks and pipes in process industries handling solutions containing chlorides,
  • Rotors, fans, shafts and press rolls where the high corrosion fatigue strength can be utilized,
  • Cargo tanks, piping and welding consumables for chemical tankers.
