Steel pipes, as conveying equipment, are widely used in industries such as oil, petrochemical, gas, and chemical sectors. As the years of use increase, some pipelines begin to experience corrosion and leakage issues, leading to frequent pipeline accidents that threaten public property safety, social stability, and industrial production. Therefore, it is crucial to ensure the safe cutting of pipelines during construction. Currently, cold cutting technology for pipelines is a relatively safe method, primarily categorized into manual pipe cutting machines (manual pipe cutters), segmented hydraulic pipe cutting machines, and electric climbing pipe cutting machines. Among these three cutting methods, manual pipe cutting machines are more affordable, safer to operate, and easy to carry. In this issue, Henan Yiwok will first introduce the manual pipe cutting tool to you, including what tools are used for manually cutting steel pipes?
