Layout requirements for honing tubes

      Honed pipes are different from ordinary pipes, so both their processing methods and pipeline layout have very special requirements. A detailed description is given around these two aspects so that the effectiveness of the honing tube can be fully utilized.
      The honing pipe is essentially a specially treated high-precision seamless steel pipe. Its good performance makes it useful in various fields. When laying out the honing tubes, both arrangement and direction should be neat and consistent, and the layers should be clear. Try to arrange it horizontally or vertically, and there are strict regulations on parallelism and verticality.
     The cutting of honed pipes is also relatively slow. If the diameter is greater than 50mm, it is best to use mechanical processing to ensure that the cut surface of the pipe is smooth and there are no defects such as burrs, scale, and slag.
