Welded Tubes
MD Exports LLP is a leading manufacturer of cold formed ERW tubing products distributed throughout India.The starting material for the production of welded tubes is rolled sheet. Sheets are cut to required size and by planing the edges bevel is made for the weld. The sheet is twisted into a tube shape and longitudinally welded.
Dimensional tolerances of welded tubes and weld
Values below are informative, are not applicable to all standards.
Outside diameter
| Outside diameter (mm) | Maximum deviation of diameter (mm) |
|---|---|
| 324 - 1 020 (1 000) | ± (0,5 % OD + 1) |
| 1 220 - 2 220 | ± 6 (5) |
Ovality of tube ends (circularity)
| Ratio OD/WT | Ovality |
|---|---|
| OD/WT < | max. 1,4 % |
| 50 <= OD/WT <= 100 | 1,4 - 2 % |
| OD/WT > 100 | Ovality is not guaranteed |
Wall thickness
| Wall thickness | Maximum deviation |
|---|---|
| WT <= 5 mm | - 0.25 / + 0.30 mm |
| 5 mm < WT <= 10 mm | - 0.35 / + 0,45 mm |
| WT > 10 mm | - 0.50 mm / upper limit is limited by the allowed deviation of the theoretical weight |
Perpendicularity of the cut
| Outside diameter (mm) | Deviation of the perpendicularity of the cut (mm) |
|---|---|
| 324 - 630 | 2 |
| 720 - 1 020 | 3 |
| 1 220 - 1 620 | 4 |
| 1 820 - 2 220 | 5 |
Camber of the welded seam
| Wall thickness (mm) | Deviation (mm) |
|---|---|
| t <= 8 | <= 2.5 |
| 8 < t <= 14 | <= 3.0 |
| 14 < t <= 40 | <= 4.0 |
