Drawn Over Mandrel (DOM) tubing is produced by electric resistance welding of carbon-steel strip followed by cold drawing over a mandrel to remove weld flash and enhance mechanical properties. This process yields:
Uniform wall thickness and concentric OD/ID.
Improved yield and tensile strength compared to standard ERW tubes.
Smooth OD/ID surfaces, requiring minimal machining.
| Property | Value |
|---|---|
| OD range | 3/16″ to 5″ (4.76 mm to 127 mm) |
| Wall thickness | 0.028″ to 0.625″ (0.71 mm to 15.88 mm) |
| Length | Random lengths 17′–24′ (5.18 m–7.32 m); cut-to-length available |
| Tolerances | ±0.005″ for OD; ±0.003″ for wall thickness |
| Surface finish | Pickled and oiled; optional honing for hydraulic applications |

High Strength-to-Weight Ratio: Superior yield and tensile properties for lightweight yet robust roll-cage structures.
Precision Dimensions: Tight tolerances reduce machining time and ensure consistent fitment.
Excellent Weldability: Low sulfur and phosphorus content facilitates gas- and arc-welding without pre- or post-heat in most grades.
Uniform Grain Structure: Cold drawing promotes refined microstructure and improved fatigue resistance.
