Spiral welded pipe: the steel strip is rolled into a pipe blank according to a certain Angle of the helix (called forming Angle), and then the pipe seam is welded together to make it, which can use a narrower strip to produce a large diameter steel pipe, and can also use a steel strip with the same bandwidth to produce a different pipe diameter steel pipe.
