Cold Drawn Seamless Tubing Vs Dom
| Feature | (CDS) Cold Drawn SeamlessTubing | (DOM) Drawn Over Mandrel Tubing |
|---|---|---|
| Process Of Manufacturing | Formed by Extruding a Solid Billet, Then Cold Drawn | Manufactured From Welded Steel That is Cold Drawn Over a Mandrel. |
| Strength | Due to the Lack of Welds Generally Stronger | Lower Strength Because Of Weld Seam |
| Seam | Seamless, Absent of Any Seams or Welds. | Weld Seam is Present |
| Surface Finish | Usually Cleaner and Smoother. | There Might Be a Few Little Defects. |
| Price | Usually More Costly Because of the Production Method. | Often Less Costly Because of the Weld Seam. |
| Tolerance | Tight Tolerances Which Might Vary | Exceptional Consistency and Dimensional Tolerance. |
| Applications | Utilized in Critical and High-pressure Applications. | Frequently Used in Mechanical and Structural Applications. |
