Cold Drawn Seamless Steel Pipe as implied is made by cold drawing a larger mother seamless pipe, which is generally manufactured through an HFS process. In the Cold Drawn Seamless process, the mother pipe is pulled through a die & plugin cold without any heating. Because of the tool on the outside and inside the surface and tolerances are better in Cold Drawn Seamless. While this is an additional process over HFS, it is necessary to get smaller size pipes that otherwise cannot be manufactured in HFS. Some applications which require close tolerances and smooth surfaces also specify the requirements to be necessarily Cold Drawn Seamless. Cold Drawn Seamless pipes & tubes are extensively used in Heat-Exchanger, Bearing & Automotive sectors. Cold drawn seamless steel pipe is used for the mechanical structure, hydraulic equipment, which has precision size, good surface finish. It can greatly reduce mechanical processing hours and improve material utilization, and improve the quality of products. High-quality cold-drawn seamless steel pipes are mainly using the 10# 20#. In addition, to ensure chemical composition and mechanical properties, it will check by the Hydrostatic test, crimping, flared, and Squashed test. Cold Drawn Seamless (CDS) as implied is made by cold drawing a larger mother seamless pipe, which is generally manufactured through an HFS process. In the CDS process, the mother pipe is pulled through a die & plugin cold without any heating. Because of the tool on the outside and inside the surface and tolerances are better in CDS. While this is an additional process over HFS, it is necessary to get smaller size pipes that otherwise cannot be manufactured in HFS. Some applications which require close tolerances and smooth surfaces also specify the requirements to be necessarily CDS. CDS pipes & tubes are extensively used in Heat-Exchanger, Bearing & Automotive sectors.
