SAF 2906/ UNS S32906 super duplex stainless steel seamless pipe

• SAF 2906/ UNS S32906 General introduction:
  • UNS S32906 is a highly corrosion resistant material specially developed for the Stamicarbon urea process. Suitable for the severe conditions in urea production, tubes in S32906 are designed to enable an oxygen-less process that increases output and safety
  • It is now a standard material for urea production and has effectively replaced X2CrNiMoN 25 22 2
  • UNS S32906 eliminates all known active forms of corrosion that occur in the urea plant, thanks to its superior mechanical properties and improved processing (like welding). The result is that for high-pressure applications it outperforms alternative and expensive metals like titanium and zirconium. Most importantly, UNS S32906 lasts longer
• SAF 2906/UNS S32906 offers numerous significant benefits, including:
  • Lower emissions
  • Lower corrosion rates, leading to longer equipment lifetimes
  • No risk for active corrosion
  • Condensation corrosion
  • Crevice corrosion
  • Stress corrosion cracking
  • Better resistant against erosion-corrosion
  • Longer running intervals between turnarounds (read resulting in extra production capacity)
  • Better mechanical properties, allowing for smaller tube and piping wall thicknesses
  • Less equipment and piping weight, leading to less investment costs
  • Improved fatigue properties
  • Improved weld ability
  • Higher stripping capacity due to increasing the inside tube diameter.
  • What's more, UNS S32906 offers you a nearly maintenance-free urea plant with a significant longer life time than any other commercially available urea process
• Size range:
  • O.D.: 14.0-219.1mm
  • Thickness:1.65-32.0mm
• Test method: ASTM A262, practice B-Ferric sulfate-sulfuric acid test for detecting susceptibility to inter granular attack in Austenitic stainless steels
• We choose the right way of packing to protect products and save your cost:
  • Plywood cases
  • Reinforced plywood case by steel angle bar
  • Plastic bags bundled
