• New method of manufacturing listed in ASTM A312 material specification (Heavily Cold Worked)
• Metallurgical equivalent of seamless
• Weld and Heat Affected Zone (HAZ) eliminated via PCC Rollmet Inc.’s patented Cold Roll Extrusion process (seam free)
• Corrosion tested by ASTM 249 – former weld/parent metal decay ratios of less than 1.0
• Corrosion tested to ASTM 262 practice A, B, C, E and F
• Lower cost than seamless
• Sizes 6” to 12” schedule 20, 10 and 5(s)

• 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 nickel alloy blanks or extruded preforms as starting material for all stainless and nickel alloy 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
