A 789 A 790, A 815 Duplex Stainless Steel Pipes

• Standards:
  • ASTM A 182, A 240, A 276,
  • A 789, A 790, A 815
  • UNS S31803, S32205
  • NACE MR0175
• Forms of duplex 2205 available at Huaan international:
  • Sheet
  • Plate
  • Bar
  • Pipe & tube (welded & seamless)
  • Fittings (i.e. flanges, slip-ons, blinds, weld-necks, lap joints, long welding necks, socket welds, elbows, tees, stub-ends, returns, caps, crosses, reducers, and pipe nipples)
  • Welding wire and welding electrode
• Usages:
  • Usage of 2205 Duplex stainless steel should be limited to temperatures below 600° F. Extended elevated temperature exposure can embrittle 2205 stainless
• The combination of Cr, Mo and Ni convey the good resistance of 2205 to chloride pitting and crevice corrosion
• This resistance is extremely important for services such as marine environments, brackish water, bleaching operations, closed loop water systems and some food processing applications
• The high chromium, molybdenum and nitrogen contents of 2205 provide corrosion resistance superior to common stainless steels, such as, 316L and 317L in most environment
• What are the characteristics of Duplex 2205:
  • High resistance to chloride stress corrosion cracking
  • Resistance to chloride pitting and crevice corrosion
  • Good general corrosion resistance
  • Good sulfide stress corrosion resistance
  • High strength
  • Good weldability and workability
• In what applications is Duplex 2205 used:
  • Chemical process vessels, piping and heat exchangers
  • Pulp mill digesters, bleach washers, chip pre-steaming vessels
  • Food processing equipment
  • Oil field piping and heat exchangers
  • Flue gas desulfurization equipment
• Available size range for seamless pipes and tubes:
  • OD: 6-168mm
  • WT: 0.5-15mm
