Then enter the annealing process, annealing with acid liquid pickling, pickling should pay attention to whether there is a large number of surface bubbles, if there is a large number of bubbles produced that the quality of steel pipe can not meet the corresponding standards. Cold-rolled seamless steel pipe is shorter than hot-rolled seamless steel pipe in appearance, the wall thickness of cold-rolled seamless steel pipe is generally smaller than hot-rolled seamless steel pipe, but the surface looks brighter than thick-walled seamless steel pipe, the surface is not too rough, the caliber is not too much burr.
