    Advantage:

    1. High dimensional accuracy, the tolerance of inner and outer diameter size can be accurate to within 0.05mm, better tolerance can controled wihthin 0.025mm. Precision H8-H10
    2. Good surfacesmoothness finish; 
    3. Good cleanliness, inside and outside surface no oxide layer
    4. Can withstand high pressure, cold bending, flaring flattening, without cracking/wrinkled
    5. Excellent overall performance, can make a variety of complex deformation and machining.


    COLD DRAWN  SEAMLESS TUBE (CDS)

    image001

    Produced  into A519 from 1020/1026 carbon steel and various alloy grades, cold drawn  seamless (CDS)  tubes have closer dimensional tolerances, better surface  finish and higher mechanical properties than the corresponding grades of hot  finished seamless tubes.
