Steel coil slitting is a manufacturing process used to cut a large coil of steel into smaller coils. The process involves feeding the coil through a slitter machine, which has multiple circular blades, or knives, that cut the coil into narrower strips. This process is commonly used in industries such as construction, automotive, and manufacturing, where the steel strips are further processed into various products.
ERW (Electric Resistance Welding) pipe and welded pipe are both commonly used in various industries for transporting fluids and gases. However, there are some key differences between these two types of pipes.
ERW pipe is made by rolling a steel plate or coil into a cylindrical shape and welding the seam using electric current. This process ensures a high-quality weld, and the resulting pipe is generally stronger than welded pipes. On the other hand, welded pipe is produced by forming a flat strip of steel into a cylindrical shape and welding the edges together. Although welded pipe is less expensive and easier to produce, its weld seam may not be as strong as that of ERW pipe.
