How is cold drawn seamless tube made?

CDS 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.

Application of 4140 chrome bar

Image
4140 is a 1% Chromium - Molybdenum high tensile steel supplied in the hardened and tempered, cold drawn or turned, precision ground, polished, chrome plated and final polished condition, with a typical base metal tensile strength of 850 - 1000 Mpa, plus a typical hard chrome plated surface hardness of HV 1000 - 1150.Characterised by an extremely smooth surface finish with excellent wear and corrosion resistance, coupled with a base material giving high strength and good impact properties, plus good machinability. 4140 hard chrome plated bar is used extensively by the hydraulic and pneumatic industries, and is employed by other industry sectors for a wide range of applications requiring higher strength. Typical applications are: Agricultural Equipment, Hydraulic Cylinders , Hoists, Jacks and other Lifting equipment, Machine Tools, Mining and Earth Moving Equipment, Pumps, Valves, Waste Disposal Transport and Equipment etc. Anbao Hydraulic is a professional manufacturer in

The Production Process Of Chrome Plated OD Tubing

  Chrome plated od tubing is also known as chrome plated hollow bar ,chrome plated tubing a very important part for producing hydraulic piston rods and roller shafts in various machines. The biggest advantage of chrome plated od tubing than normal chrome plated rod is that the unit weight is light, people can greatly reduce the weight of the hydraulic piston rod, when design the hydraulic cylinders . The Production Process Of Chrome Plated OD Tubing Step 1. Get the steel tubes heat treated as per customers’ request. Step 2. Cutting the raw material hollow rod into lengths Step 3. Straightening the hollow rods Step 4. Peeling on the steel hollow rods Step 5. Straightenning Step 6. Grinding the steel hollow rods Step 7. Straightening the ground hollow bars. Step 8. The second grinding process Step 9. Polishing on outer diameter surface Step 10. Chrome plating Step 11. Final polishing Step 12. Final inspection Anbao Hydrualic is a professional  chrome plated ID tubing and hollow bar m
