STAINLESS AND DUPLEX

Rollmet seamless sets the standard for large diameter stainless steel and duplex stainless steel pipe and tube for the power, petrochemical and nuclear industries.
PRODUCTION DETAILS COLD ROLL EXTRUSION METHOD
  • Austenitic Stainless Steel ASTM A312/376 – 300 SERIES
  • Ferritic/Austenitic Stainless Steel ASTM A790 – S31803 DUPLEX and S32750 SUPER DUPLEX
  • Rollmet seamless pipe and tube is available in many other alloys such as zirconium, titanium, Alloy 200, 400, 600, 625, 718, 825, Alloy 20 and C276
  • Specializing in large diameter thin wall pipe and tube
  • 140 RA or better – I.D. finish
  • Single random lengths – ASTM allowables
  • Fine grain size for stainless grades runs 6 to 8 typical
  • Wall tolerances better than ASTM allowables
  • 50 years of manufacturing experience
  • Minumum 35% cold work
  • Cold Roll Extruded solid-solution alloy pipes offer greater strength than conventional manufactured pipe/tube because of the fine grain size achieved through cold working and recrystallization
  • Cold Roll Extrusion, as a net process, achieves final pipe dimensions through metal displacement with very little waste
  • Cold Roll Extrusion is performed at ambient room temperature
  • Cold Roll Extrusion utilizes precision stainless steel and duplex starting blanks or extruded preforms as starting material for all stainless and duplex and super duplex production
  • Isotropic properties can be achieved either as a cold worked tubular or in all finished annealed tubular products
  • Enhanced corrosion resistance is achieved through ASTM 5 or finer grain size
