Nansteel - Model SMLS -Seamless Steel Pipe/Tube

Sizes of seamless pipe

• Out diameter: 1/2"-36" (21.3mm-914.4mm)
• Thickness: 2.11mm-60mm ( SCH10, SCH20, SCH40, SCH80, STD, SCH120, SCH160, XXS)

Continuous rolling is the most advanced technology for producing hot rolled seamless steel pipe of modern industry.It creates high quality seamless steel pipe efficiently, even for high alloy pipe and light wall pipe. Hot rolling process can significantly reduce energy consumption and reduce costs. High metal plasticity during hot rolling.
Size Range: 2″(60.3mm) to 20″(508mm)
Delivery Condition: As roll/ Normalized

Used for producing small size pipe. There are several times of cold forming process, so yield strength and tensile strength values increase, while elongation and toughness values decrease. A heat treatment must to be applied for each cold forming operation. cold drawn pipe maintains precise dimension, smooth surface and shining appearance.
Size Range: 1/2″(21.3mm) to 1-1/2″(48.3mm)
Delivery Condition: Cold Drawn and Stress Relief, Annealed, Normalized

As another type of cold forming process, cold rolled mill also works at room temperature to stretch large size pipe to required small size. Comparing cold drawn mill ,it takes pilger mill with fewer cold forming processes and lower productivity, but come out the pie in much precise size and shinning apperance.
Size Range: 1/2″(21.3mm) to 1-1/2″(48.3mm)
Delivery Condition: Cold roll, Annealed, Normalized
