Abstract
PURPOSE:To improve the quality by manufacturing tubes in a manufacturing stage where plural piercing machines and one or more plug mills, one or more furnaces heating a tube stock at a workable temp. and installed in front of the plug mills. CONSTITUTION:A pierced and formed tube stock is expanded and thinly rolled by plural piercing machines. Then, heating the stock at a workable temp. by at least one or more furnaces and a tube having a wall thickness/outside diameter ratio of <=2% is obtained by adjusting its outside diameter and wall thickness by at least one or more plug mills. By this method, the product of excellent quality is obtained.
