Dimensional tolerances for ABS Grade D shipbuilding plates
1. Thickness tolerance
| Thickness, t | Tolerance |
|---|---|
| t ≤ 10 mm | ±0.5 mm |
| 10 mm < t ≤ 20 mm | ±0.8 mm |
| 20 mm < t ≤ 50 mm | ±1.0 mm |
| t > 50 mm | ±1.5 mm |
* Thickness tolerance requirements: To ensure uniform steel plate thickness and prevent any impact on welding and assembly accuracy.
2. Width tolerance
| Width | Tolerance |
|---|---|
| ≤ 2000 mm | ±5 mm |
| > 2000 mm | ±8 mm |
* Width tolerance requirements: To ensure that the width of the steel plate meets design specifications and to minimise the joint gap.
3. Length tolerance
| Length | Tolerance |
|---|---|
| ≤ 12000 mm | ±10 mm |
| > 12000 mm | ±15 mm |
* Length tolerance requirements: To avoid difficulties in joining caused by length deviations.
4. Flatness tolerance
| Flatness | Tolerance |
|---|---|
| Per meter | ≤ 3 mm/m |
| Total (length ≤ 12000 mm) | ≤ 10 mm |
* Flatness tolerance requirements: To ensure the surface of the steel plate is flat, facilitating assembly and welding, and to avoid excessive welding stresses caused by flatness deviations.
Note: The tolerance ranges given above are for reference only; as these may vary depending on the product batch, please contact our specialist sales team for specific figures.
