Commercial Seamless NICKEL ALLOY
Rollmet seamless pipe and tube sets the standard for large diameter high nickel alloy pipe and tube for the power, petrochemical and nuclear industries.
PRODUCTION DETAILS COLD ROLL EXTRUSION METHOD
  • Seamless Nickel Alloy pipe to ASTM/ASME B/SB 161, 163, 165, 167, 407, 423, 444, 622 & 729 specifications
  • Seamless Nickel Alloy pipe meets ASTM/ASME B/SB829 dimensional requirements for cold worked pipe and tube
  • Seamless Nickel Alloy pipe furnished in cold worked and or cold worked annealed condition
  • 15 ft to 24 ft single random lengths – some sizes in 10 to 15 ft lengths
  • Up to 40 ft lengths in CRA Casing and Line Pipe
  • Minumum 35% cold work
  • 50 years of manufacturing experience
  • 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 nickel alloy blanks or extruded preforms as starting material for all nickel alloy production
  • Isotropic properties can be achieved either as a cold worked tubular or in a finished annealed tubular
  • Enhanced corrosion resistance is achieved through ASTM 5 or finer grain size
