Cold drawn seamless steel pipe production technique


Precision bright tube may be a quite high preciseness steel tube material once being processed by fine drawing or cold rolling.Due to the preciseness bright tube within and outdoors the wall while not chemical compound layer, below air mass while not run, high preciseness, high end, cold bending while not deformation, flaming, flattening while not cracks so on, thus chiefly used for the assembly of gas or hydraulic parts of the merchandise, like cylinder or oil cylinder, will be seamless tube, additionally has welded tube.The chemical parts of preciseness bright tube are carbon C, silicon Si, atomic number 25 Mn, sulfur S, phosphorus P, Cr.
