Size Range: 2″(60.3mm) to 20″(508mm) Delivery Condition: As roll/ Normalized Cold drawn 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. Comparing hot rolled pipe, 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/ Hard, Cold Drawn / Soft, Cold Drawn and Stress Relief, Annealed, Normalized Cold rolled 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 Uses For Chilled Water, Steam, Heat Exchanger, Boiler Manufacturing For Construction, Structure,Industrial, Fire Fighting For Drain/sewage, Dredging, Irrigation For Oil and Gas For Marine/offshore
