Claims (11)
- 外側に位置する支持層(1)と、内側に位置する少なくとも1つの被覆層(2)とを備える多層の大径管を製造する方法であって、
支持層(1)用の、予め規定された初期曲げ半径(RB0)に予め曲げられた支持金属薄板と、被覆層(2)用の、予め規定された初期曲げ半径(RA0)に予め曲げられた少なくとも1つの被覆金属薄板とを用意する方法ステップと、
前記予め曲げられた少なくとも1つの被覆金属薄板を、前記予め曲げられた支持金属薄板の内面に載置し、両金属薄板の、曲げ軸線の方向に延びる長手方向縁部同士を互いに平行な方向に揃えて位置決めして、支持層(1)と前記少なくとも1つの被覆層(2)とを形成する方法ステップと、
前記少なくとも1つの被覆金属薄板の少なくとも両長手方向縁部(3a,3b,3c,3d)を前記支持金属薄板に材料接続的に結合する方法ステップと、
互いに材料接続的に結合された支持層(1)と前記少なくとも1つの被覆層(2)とから成る複合体を曲げ機械によって、材料接続的に結合されていない当付け領域で摩擦接続的な結合を行いつつ丸め成形して、スリットを備えた多層の大径管を製造する方法ステップと、
前記スリットを備えた多層の大径管の残されたギャップを溶接による長手方向シームで閉鎖する方法ステップと、
を上記順序で有することを特徴とする、多層の大径管を製造する方法。 - 前記材料接続的に結合する方法ステップに際して、前記少なくとも1つの被覆金属薄板の、曲げに関して環状に延びる縁部(4)も少なくとも部分的に前記支持金属薄板に結合しかつ/または材料接続的な結合を前記被覆金属薄板の貫通溶接によって行う、請求項1記載の方法。
- 予め曲げられた複数の分割被覆金属薄板を、前記内面に周方向で互いに並置し、該内面で少なくとも前記分割被覆金属薄板の両長手方向縁部に沿って前記支持金属薄板に個別に材料接続的に結合する、請求項1または2記載の方法。
- 種々異なる材料、それぞれ異なる厚さおよび/または周方向に延びるそれぞれ異なる幅の前記分割被覆金属薄板を使用する、請求項3記載の方法。
- 前記支持金属薄板の前記内面の初期曲げ半径(RB0)と、前記少なくとも1つの被覆金属薄板の外面の初期曲げ半径(RA0)とを互いに等しいサイズに選択する、請求項1から4までのいずれか1項記載の方法。
- 両初期曲げ半径(RB0,RA0)を、完成した状態に曲げられた前記大径管の半径の少なくとも2倍のサイズに選択する、請求項1から5までのいずれか1項記載の方法。
- 前記支持金属薄板の初期曲げ半径(RB0)と、前記少なくとも1つの被覆金属薄板の初期曲げ半径(RA0)とを、支持層(1)と前記少なくとも1つの被覆層(2)とから成る前記材料接続的な複合体を丸め成形して、前記スリットを備えた大径管を形成する際に、膨れまたは皺形成が回避されるようなサイズに選択する、請求項1から6までのいずれか1項記載の方法。
- 丸め成形して、前記スリットを備えた大径管を形成する間に、前記少なくとも1つの被覆金属薄板の圧縮が生じるように、両初期曲げ半径(RB0,RA0)を選択する、請求項1から7までのいずれか1項記載の方法。
- 前記支持金属薄板よりも高い降伏点を有する材料を含む前記少なくとも1つの被覆金属薄板を選択する、請求項1から8までのいずれか1項記載の方法。
- 支持層(1)と被覆層(2)とから成る前記材料接続的な複合体を丸め成形して、前記スリットを備えた大径管を形成する際に、前記少なくとも1つの被覆金属薄板の圧縮限界を、予め規定された程度、意図的に超過させる、請求項1から9までのいずれか1項記載の方法。
- 丸め成形して前記スリットを備えた大径管を形成した後に残されたギャップを、支持層(1)から形成された支持管をサブマージアーク溶接法により溶接し、これに続いて、こうして形成された内側の溶接シームを、同種の合金または被覆層(2)の材料に適した合金での肉盛溶接により覆うようにして閉鎖する、請求項1から10までのいずれか1項記載の方法。
