After the surface does not respond to cracks, the round tube must be cut by a cutting machine and cut into a blank of about one meter in length. Then enter the annealing process. The annealing should be pickled with acid liquid. When pickling, pay attention to whether there is a lot of blistering on the surface. If there is a lot of blistering, it means that the quality of the steel pipe does not meet the corresponding standards. In appearance, cold-rolled seamless steel tube is shorter than hot-rolled seamless steel tube. The wall thickness of cold-rolled seamless steel tube is generally smaller than that of hot-rolled seamless steel tube, but the surface looks brighter than thick-walled seamless steel tube.
