Abstract

　従来技術に比べてより一層、管の長手方向肉厚分布を均一にすることが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、マンドレルバーＢの常温での長手方向外径分布を測定する第１ステップと、マンドレルミルＭでの延伸圧延工程に供した後の当該マンドレルバーの長手方向温度分布を測定する第２ステップと、当該マンドレルバーが挿入されて延伸圧延された管の熱間状態での長手方向肉厚分布を測定する第３ステップとを含む。そして、第１～第３ステップで得られた各パラメータに基づき、当該マンドレルバーの延伸圧延時における長手方向外径分布を算出する第４ステップと、次のタイミングで当該マンドレルバーを管の内面に挿入して延伸圧延する際に、当該マンドレルバーの長手方向外径分布に基づいて、孔型ロールＲの圧下方向の設定位置を調整する第５ステップとを含む。
