ASTM A335 P11 Seamless Pipe

Size: 10 Inch

Thickness: SCH60

Material: ASTM A335 P11

Type: Seamless
Length: 12 Meter

Standard: ANSI B36.10
Production Process of Seamless Steel Pipe: Hot Roll Draw and Cold Roll Draw

1.Hot-Rolled Seamless Steel Pipe Production Process: Tube preparation and inspection, Tube Heating, Perforation, Rolling, Tube Reheating, Sizing, Reducing, Heat Treatment, Finished Pipe Straightening, Finishing, Inspection, etc. The Outer Diameter of the Hot-Rolled Seamless Steel Pipe＞ 32mm, Wall Thickness is between 2.5-200mm.         

2.Cold-Rolled (Drawing) Seamless Steel Pipe Production Process: Billet Preparation, Pickling Lubrication, Cold Rolling (Drawing), Heat Treatment, Straightening, Finishing, Inspection, etc. The production process of Cold-Rolled Seamless Steel Pipe is relatively complex, Outer Diameter can be 6mm,Wall Thickness can be 0.25mm, the outer diameter of the thin-walled pipe can be 5mm, the wall thickness is less than 0.25mm.

3.Cold Rolling has Higher Dimensional Accuracy than Hot Rolling
