摘要： PROBLEM TO BE SOLVED: To easily adjust circumference of a spiral steel pipe while preventing defective offset of welding in the process of manufacturing the spiral steel pipe. SOLUTION: The inside circumference or the outside circumference in the portion which is formed into a pipe shape of the spiral steel pipe 7 in the middle of manufacturing is measured in a position which is just after welding. The variation of the inside circumference or the outside circumference on the basis of the measured value of the inside circumference or the outside circumference of the spiral steel pipe 7 is obtained. The spiral steel pipe 7 in the middle of the manufacturing just after internal welding is rotationally moved so that the inside circumference or the outside circumference of the spiral steel pipe 7 approaches the target value. At this time, the corrected angle to a steel strip 2 of the spiral steel pipe 7 is obtained from the variation of the outside circumference and the spiral steel pipe 7 is rotationally moved to the steel strip 2 by the corrected angle.
