CDS Tube: Product Description
What is CDS tube(cold drawn seamless tube)?
The CDS tube is short for Cold Drawn Seamless Tube, which is a high-quality steel tube that is produced through a unique cold drawing process. Unlike regular seamless tubes, CDS tubes are made by drawing a seamless tube through a die and over a mandrel without welding. This results in a tube with a finer grain structure, improved dimensional accuracy, consistent wall thickness, and a smooth surface finish.
CDS tubes are popular in various industries for their high precision, high pressure resistance, and close tolerances. They are commonly used in applications where dimensional accuracy and surface finish are crucial, such as in hydraulic and pneumatic systems, automotive components, medical equipment, and industrial machinery.
YIWU Hydraulics is a leading manufacturer of CDS tubes with a large production capacity. Our CDS tubes are made from alloy and carbon steels, ensuring they meet specific mechanical needs such as machining or heat treating. The cold drawing process improves the mechanical properties of the tubes, resulting in uniform outside and inside diameters, improved surface finish, increased durability, and higher mechanical properties compared to hot rolled or hot extruded tubes.
