Cold Drawn Seamless Tubes: Product Description
What is cold drawn seamless tube (CDS tube)?
Cold drawn seamless tube is a type of steel tube that is produced by drawing a seamless tube through a die and over a mandrel without welding. This process results in a tube that has a much finer grain structure and improved dimensional accuracy compared to a regular seamless tube. The process of cold drawing also results in a tube that has a consistent wall thickness and improved surface finish.
CDS tube is short name of the Cold Drawn Seamless Tube, this product is a popular choice for mechanical tubing in various industries due to its high precision, high pressure resistance, smooth surface finish, and close tolerances. It is made from alloy and carbon steels to meet specific mechanical needs such as machining or heat treating. The tubes are commonly used in applications where dimensional accuracy and surface finish are important, such as in the production of hydraulic and pneumatic systems, automotive components, medical equipment, and industrial equipment.
As a leading precision pipe manufacturer, Guangxi has a large production capacity for Cold Drawn Seamless Tubes. Our CDS Tubes are made from hot rolled round rods that are pierced and then subjected to the cold drawing process. This process improves the mechanical properties and reduces the cost and time of machining. The result is a CDS Tube with uniform outside and inside diameters, improved surface finish, increased mechanical properties, and higher durability compared to hot rolled or hot extruded tubes.
