There is a cold drawing process in the processing of stainless steel heat exchange tubes, that is, cold processing. In order to make stainless steel heat exchange tubes meet higher requirements for cold processed products during cold processing. Cold drawing can be through plug cold drawing, mandrel cold drawing and free cold drawing.
So do you know the benefits of cold working of stainless steel heat exchange tubes?
① It can improve the surface of stainless steel heat exchange tubes, improve surface finish and corrosion resistance.
② Improve the dimensional accuracy. After cold rolling or cold drawing with the mandrel, not only the outer diameter accuracy can be improved, but also the wall thickness accuracy of the heat exchange tube can be improved.
③ It can produce steel pipes with smaller diameter and thinner wall.
④Cold deformation combined with external treatment can also improve the mechanical properties of heat exchange tubes.
⑤ Special size and special section can be made (except round shape).
