Description. Cold drawn seamless tube, also called CDS tube, is made from the hot billets by piercing, subsequent rolling, and elongating process to be passed through the die over a mandrel plug and finally to reach the designed accurate diameter and wall thickness.Cold Drawn Seamless (CDS) manufacturing process can greatly increase the strength of the seamless steel pipe and makes it very
Difference between ERW, DOM and Seamless Tube Mar 15, 2017 · The first stages of manufacturing are identical to ones used to make electric resistance welded tube, but in the finishing stages the entire flash weld is removed and the tube is cold drawn over a mandrel. The cold drawn process provides the tube with better dimensional tolerances, improved surface finish and the strongest weld strength achievable.
Global Seamless Tubes & Pipes - Manufacturer and Supplier We manufacture and stock many seamless tubes and pipes from cold drawn to hot-rolled, in standards of ASTM A210, API 5L, ASTM A53, JIS G3454/3455/3456, and many more. We also make Structure Tube for mechanical applications, Fluid Pipes for water and other low-pressure liquid supply, Boiler Pipes for hydraulic system, and line pipes for oil and
