The special plasma round pipe cutting machine is a cutting equipment developed by Changzhou Runyun for the steel pipe industry. The equipment solves the problem of cutting the scrap part of the cold-drawn steel pipe fixture, and realizes the scrap cutting of the cold-drawn steel pipe during processing. There is no need for additional hoisting and sawing, and the cutting is completed in seconds with one click. It perfectly replaces the slow sawing machine and adapts to pipes of different diameters and wall thicknesses, greatly improving factory production efficiency.
