When wrapping the pipeline, there are generally two ways of wrapping. The first is to "pipe" turn and "tie", that is, while rotating the pipeline, move the cold wrapping tape roll at a constant speed to ensure that the cold wrapping tape is spirally wrapped around the pipeline. This prevention requires a single section of pipeline. The second method is to "pipe" fixed and "tie" moving, that is, the pipeline is completely motionless, and the tape roll is operated to make the cold wrapping tape spirally wrapped around the pipeline. It is aimed at pipelines that have been connected or are longer.
