Electrolytic cutting. This method is suitable for cutting stainless steel pipes. Firstly, mark the cutting line on the pipe with tape, leaving a slight gap. Then, prepare two clamps and a piece of cotton thread, securing the thread to the clamps and wrapping it around the pipe to ensure it is tightly against the surface. Next, prepare a charger (such as a 14V computer charger) and a cup of saltwater (mix tap water with salt and stir until well combined). Connect one end of the charger to the clamp and plug the other end into the outlet. Immerse the pipe in the saltwater; through the electrolysis reaction, the pipe will break at the point where the cotton thread is wrapped.12
Mechanical cutting. Suitable for smaller seamless steel pipes, requiring a flat and smooth cutting section. Common mechanical cutting methods include sawing and abrasive wheel cutting.4
Flame Cutting. Suitable for large seamless steel pipes, it offers the advantages of fast cutting speed and low cost, but may cause deformation and oxidation. Common flame cutting methods include gas cutting and plasma cutting.
Laser Cutting. Suitable for seamless steel tube cutting in various materials, especially thin-walled steel tubes. This method offers high precision and speed, but requires advanced operator skills.
High-pressure water cutting. It's an eco-friendly and efficient cutting method with excellent cut quality, no deformation, and no pollution, although the equipment costs are high.
