Cold Drawn Seamless Pipe

Cold drawn seamless, as implied, is made by cold drawing larger mother seamless pipes, which are typically manufactured using the HFS process. In the seamless cold drawing process, the main pipe is pulled through the mold and cold plugged without any heating. Due to the better surface and tolerance of the tool on both the external and internal surfaces in seamless cold drawing. Although this is an additional process of HFS, smaller pipes must be obtained, otherwise they cannot be manufactured in HFS. Some applications that require tight tolerances and smooth surfaces also specify the requirements for cold drawn seamless pipes. Cold drawn seamless pipes and tubes are widely used in the fields of heat exchangers, bearings, and automobiles. The mechanical structure adopts cold drawn seamless steel pipes, hydraulic equipment, precise dimensions, and good surface smoothness. It can greatly reduce machining time, improve material utilization, and improve product quality. High quality co…
