TUBE HAVING A HELICAL SEAM AND METHOD FOR PRODUCING A TUBE HAVING A HELICAL SEAM
The invention relates to a tube (2) having a helical seam, comprising at least one cylindrical tube portion which consists of a single-piece metal strip (n+x) that is bent in the manner of a helical line, is welded at a continuous helical seam line (3) and has a varying wall thickness over its length. The invention also relates to a method for producing a cylindrical tube (2) having a helical seam, in which method at least one metal strip (n+x) is deformed in the manner of a helical line by means of a bending device in order to form a slotted tube and the metal strip (n+x) is welded at the strip edges brought together at the helical seam line, and wherein a metal strip having a varying wall thickness over its length is used as the metal strip (n+x).
本发明涉及一种具有螺旋缝的管(2)，其包括至少一个筒状的管区段，该管区段由金属带(n+x)构成，该金属带一体形成、螺旋线形地弯曲并且在连续的螺旋缝线(3)处进行焊接，并且金属带在其长度上具有变化的壁厚。本发明还涉及一种用于生产筒状的具有螺旋缝的管(2)的方法，在该方法中，借助于至少一个弯曲装置使至少一个金属带(n+x)螺旋线形地变形成有缝管，并且对金属带(n+x)在带边缘处进行焊接，该带边缘在螺旋缝线处汇合，并且其中，将在其长度上具有变化的壁厚的金属带用作金属带(n+x)。
