Cold rolled steel pipe is manufactured through a cold rolling process at room temperature (below the metal recrystallization temperature). It is typically produced from hot - rolled seamless steel pipe billets.
In terms of characteristics, it boasts precise dimensions with tight tolerances for outer diameter, inner diameter, and wall thickness. The surface finish is excellent, with high smoothness and no oxide scale defects. Moreover, the cold working process induces work hardening, resulting in high strength and hardness. It can also produce extremely thin - walled pipes that are difficult to achieve by hot rolling.

Cold drawn steel pipe is produced by drawing hot - rolled or cold - rolled seamless steel pipes through a die at room temperature.
It features extremely precise dimensions with very strict control over outer diameter, inner diameter, and wall thickness. The surface quality is superior, with high smoothness and minimal surface defects. The cold drawing process enhances the mechanical properties, giving it high tensile strength, yield strength, and toughness. It can be made into pipes with complex cross - sectional shapes and very small diameters, which is difficult for other processes.
