    Cold Drawn Steel Pipe For Ecuador

    Cold drawn steel pipe is a kind of steel pipe, that is, it is classified according to different production processes, which is different from hot rolled (expanded) pipe. In the process of expanding the diameter of a wool pipe blank or a raw material pipe, a plurality of cold drawing processes are carried out. Accuracy and surface quality are obviously superior to those of hot-rolled steel pipe, but due to technological constraints, its diameter and length are limited to some extent.
