The production of pipes by the spiral method is one of the methods of producing large-diameter seamed pipes, in which the welding seam of the pipe is in the form of a spiral. In this pipe production method, steel coil is used as raw material. The very significant advantages of large-diameter pipe production by the spiral method have established the position of this production method in the world as one of the best methods.
