Cold Drawn Seamless Tubes (CDS) Cold Drawn refers to a part in the seamless tube making the process that creates an end-product that is physically superior to its hot finished counterpart. A Hot Finished Seamless(HFS) tube is a rougher look to it as compared to the sleeker and smoother CDS. Putting a tube through the cold drawn process increases its tolerances and strength, however, HFS does have its benefits. These seamless tubes are used in applications requiring a lot of strength. Cold Drawn Seamless tubes offer tighter tolerances compared to the alternative Hot Finished Seamless tube, and offers stronger physical properties compared to other mechanical tubing. CDS is popular in the hydraulics, being used to make hollowed chrome plated telescopic cylinders and hydraulic rods. It is also popular for large bore, heavy walled, high pressure hydraulic cylinders. Cold Drawn Seamless tubes also find uses in heavy equipment manufacturing such as cranes and garbage trucks. ...
