316Lmod/724L, urea steel seamless pipe

316Lmod/724L, urea steel seamless pipe

• Equal grades: 316LMOD/1.4435/TP316LN/724L
• 316Lmod--urea 316L modified grade has been specially developed for Urea plant applications
• It is a 316L modified stainless steel with extra-low silicone content and substantial higher molybdenum contents
• The low carbon content, combined with a well balanced chemistry (low silicone and nickel content close to 14%) makes the alloy fully austenitic, free of intermetallic phase precipitations
• The ferrite level is kept under 0.5% in the solution annealing and water quenched conditions
• The alloy is designed for improved corrosion resistance properties in urea- carbonate environments
• Typical maximum corrosion results required following different specifications after Huey tests (ASTM A262 C - five periods of 48 h.) are: maximum weight loss lower than 3,3 µm/48 h (ª 130 mg/dm² per 24 h.), with a maximum depth for micro cracks of 200 µm in the long direction and 70 µm in the transverse direction
• Test & inspection plan:
  • 100% PMI/spectro chemical analysis tests
  • 100% dimension tests & 100% visual examination
  • Tension test, flaring tests (for seamless tube/pipe)/flange tests (for welded tube/pipe), hardness test, reversed flattening test (for welded tube/pipe), flattening test (for seamless tube/pipe)
  • 100% hydrostatic test/100% non-destructive tests
• Option test & inspection plan:
  • Straightness test
  • Roughness test
  • Crystalline phase analysis
  • Inter-granular attack tests
  • Impact attack test under low temperature
  • U-bend balling pass test u
  • PT test on bending area
  • Ultra-sonic testing
• Documents provided by Huaan International:
  • A.MTC (material test certification) according to en10204/3.1 or en 10204/3.2
  • Raw material certification
  • All the test & inspection reports as per po and standards
  • Heat treatment report
  • Shipping notification before shipment
