Various measures to improve the wall thickness of high-precision cold drawn pipes

       In the production process of high-precision cold drawn pipes, the thickness of the pipe wall is difficult to control. Are there any optimization measures that can be adopted in this regard?
       If you want to change the wall thickness of cold-drawn tubes, you must do it from all angles. For example, when the tube blank is heated, you must maintain uniformity and ensure a smooth and slow rise and fall of the temperature. At the same time, you can also adjust the equipment to confirm the installation position and various parameters of the centering roller; and the rolling center line of the piercing machine and the center line of the piercing car must be the same to avoid bad situations.
       In addition, the production tools of cold-drawn tubes must be replaced in time, mainly the mandrel, which must be maintained in a better working condition and with higher precision. After improving all aspects of technology and equipment, the wall accuracy of cold-drawn tubes will increase.
