What is a cold drawn seamless tube?

The “Cold Drawn Seamless tube” or CDS tube is a type of steel tube created by drawing a seamless tube through a die and mandrel without welding. This method leads to a tube with a finer grain structure, improved dimensional accuracy, consistent wall thickness, and better surface finish.

CDS tubes are widely utilized across several industries for their high precision, strength, and resistance to pressure and corrosion. They are commonly used in applications requiring accurate dimensions and a superior surface finish, such as in the manufacture of hydraulic and pneumatic systems, automotive parts, medical devices, and industrial equipment.

Our CDS tube is utilized to produce hydraulic cylinder tube and chrome plated hollow bar, in addition to its other applications across various industries. Some common examples include:

  • Automotive Industry: CDS tubes are utilized in producing automotive components like suspension systems, fuel systems, and steering systems.
  • Construction Industry: Their high strength and durability make CDS tubes a popular choice in construction projects for buildings, bridges, and other structures.
  • Industrial Equipment: CDS tubes are used in the manufacturing of boilers, heat exchangers, and pressure vessels due to their resistance to corrosion and pressure.
  • Oil and Gas Industry: They are commonly used in the oil and gas industry for the production of pipelines and other components due to their corrosion and pressure resistance.
  • Hydraulics and Pneumatics: CDS tubes are used as shafts and pistons in hydraulic and pneumatic systems because of their precision and strength.
  • Medical Equipment: They are used in producing medical equipment like orthopedic implants and surgical instruments due to their precision and biocompatibility.

The specific application of CDS tubes will vary depending on the user’s requirements, such as size, strength, pressure resistance, and corrosion resistance.
