Abstract

　管の目標肉厚が異なる場合であっても、同一外径のマンドレルバーを用いることができると共に、管の周方向偏肉を効果的に抑制可能な継目無管の製造方法を提供する。 　本発明に係る継目無管の製造方法は、延伸圧延後の管の目標肉厚ｗｔが複数存在する場合に、複数の圧延スタンドの内、仕上スタンドに配設される孔型ロール１のみを、下記の式（１）の条件を満足すると共に、各目標肉厚毎に異なる溝底曲率半径Ｒ１を有する孔型ロールに変更して管を延伸圧延する工程を含むことを特徴とする。 　－０．１ｍｍ≦（１－ｃｏｓθ）・Ｓ≦０．１ｍｍ　・・・（１） 　ここで、上記式（１）におけるθは、各圧延スタンドに配設される孔型ロールの個数をｉ（ｉ＝２～４）とした場合にθ＝９０／ｉ（°）で表され、Ｓは孔型ロールのオフセット量（ｍｍ）を意味する。
