ABSTRACT: Cold Drawn Seamless Mechanical Tubing (CDS) is a cold drawn steel tube which offers uniform tolerances, enhanced machinability and increased strength and tolerances compared to hot-rolled products. Produced from hot rolled , the cold drawing process increases the tube’s physical properties and offers better tolerances and reduced machining allowances over hot finish seamless.

STOCKED SIZE RANGE:

  • 1.000″ to 10.000″ O.D. with 0.100″ to 1.500″ Wall Thickness
  • Stocked in 16.000′ – 29.000′ random lengths (cut to length available)

MANUFACTURING PROCESS:

CDS(cold drawn steel) seamless tube and pipe is produced by piercing hot billets and subsequent rolling which reduces their diameter and elongates them. This material is then passed through a die and over a mandrel plug to produce an accurate size and gauge which is the essence of the cold drawing process.

BENEFITS OF COLD DRAWN SEAMLESS TUBING:

HIGHER STRENGTH & HARDNESS PROPERTIES

  • Cold drawing increases the strength of the tube therefore making it very suitable for safety and performance critical applications.

SIZE ACCURACY

  • Due to the nature of the manufacturing process drawn tubes can be manufactured to close dimensional tolerances, achieving consistent diameter and thicknesses throughout.

ENHANCED APPEARANCE

  • Cold drawn seamless tube usually has a shinier look with no weld lines increasing the aesthetics of the products in which it is incorporated.

UNIFORM MICRO-STRUCTURE

  • Due to the cold drawing process, CDS has excellent micro-structure uniformity and consistency.

EASIER TO MACHINE

  • Due to the superior strength and hardness, it produces a better machined surface and therefore a better-looking component.

SUPERIOR FINISH IN SUBSEQUENT MANIPULATIONS

  • As cold drawn tubes have a glossier, no-seam finish they also produce better end products from processes such as dipping, etching and anodizing.
