    FERRITIC ALLOY

Rollmet seamless large diameter ferritic alloy pipe sets the standard in thin wall pipe and tube applications for the power and petrochemical industries.
PRODUCTION DETAILS COLD ROLL EXTRUSION METHOD
  • Ferritic Alloy Steel ASTM/ASME A335 – P5, P9, P11, P22, P91, P92, 125 to 150 RMS ID finish
  • 15 to 24 ft single random lengths
  • ASTM +/- 1% ovality tolerance met on all seamless pipes
  • All seamless pipe within +10% /-5% of the nominal weight per ft for the entire length
  • All seamless pipe within +/- 12.5% of the nominal wall call out per ASTM Specification
  • Specializing in large diameter thin wall ferritic alloy steel pipe
MANUFACTURING RANGE
  • 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 ferritic alloy starting blanks or extruded preforms as starting material for all ferritic alloy production
  • Isotropic properties can be achieved in all finished annealed tubular products
  • Enhanced corrosion resistance is achieved through ASTM 5 or finer grain size
QUALITY CERTIFICATIONS
  • AS9100/ISO9001
  • ISO 9001 approved
  • AD2000-Merkblatt W0 approved

* Wall sizes available up to 1.5” on certain pipe sizes
