          Application of mandrel in pipe fitting production

          pipe expanding machineelbow machine
          In the production of pipe fitting, the choice of reasonable mandrel diameter and sufficient lubrication are the essential factors to ensure the quality of the elbow.
          After the shape of the mandrel is selected, high quality pipe fitting cannot be guaranteed, and the clearance between the mandrel and the inner diameter of the pipe is also an important factor affecting the quality of the bend. 
          For example, our elbow machine needs to use a bending mandrel;Straight mandrel is required for pipe expanding machine.
