A cold-drawn pipe is tubing drawn cold through steel or carbide die to elongate and improve its dimensional accuracy. The cold drawing process may or may not have a mandrel or a floating plug inserted inside the tube to help enhance the wall thickness.
Cold drawing costs more than hot rolling as the manufacturing process involves more labor, time, and energy. However, the result of this process is also superior, with the cold drawn steel pipe revealing a better surface finish and more even concentricity.
