When using honing pipes, please pay attention to:
       When dents appear on the honing tube, the service life of the components will be affected, and the cylinder components will also affect the normal use of the entire system. What exactly causes concave folds to occur? There are just a few possibilities:

       First, the diameter reduction during the cold drawing process is too large or the steel pipe hammer head transitions too quickly;
       Second, the thickness of the pipe wall is uneven and partially too thin;
       Third, the honing equipment is too old and cannot meet the processing requirements of pipes.
   After these numerous improvements, similar bad flaws should be able to be improved.
