Product Description
Tolerances to BS EN 10296-2 for SUS304 Stainless Steel Strength Pipe
SUS304 Stainless Steel Strength Pipe Introduction
Unlike the standards for flat and long products, the standards for stainless steel tube products contain information on tolerances. This is possibly because the tolerance requirements for tubes are simpler to define.
SUS304 Stainless Steel Strength Pipe Straightness
| OD | Deviation from straightness on tube length L |
| > 33.7 mm | 0.0020 L |
| < 33.7 mm | Agreed at time of enquiry and order |
Example 50mm dia tube x 6000 mm long maximum deviation from straightness = 12 mm
A tighter tolerance of 0.0015 L can be agreed at time of order and enquiry.
SUS304 Stainless Steel Strength Pipe Outside Diameter
| OD | Tolerance on OD including ovality |
| < 168.3 mm | ± 0.75 % or ± 0.3 mm whichever is the greater |
| > 168.3 mm | ± 1.0 % |
A tighter tolerance can be agreed at the time of enquiry and order on tubes of < 114.3 mm of ± 0.5 % or ± 0.15 mm whichever is the greater.
Wall Thickness
For all tube sizes tolerance on wall thickness is ± 10 % or ± 0.2 mm whichever is the greater.
Weld Seam Height
The outside weld bead of HF SUS304 Stainless Steel Strength Pipe shall be removed completely i.e. flush with the outside surface of the tube.
The maximum heights of the external and internal weld seams shall otherwise be as given in the table below:
| Weld finish | Maximum height of weld seam | |
| Wall thickness (T) < 8 mm | Wall thickness (T) > 8 mm | |
| Finish A | 0.20 T + 0.5 | T/3 |
| Finish B for D < 114.3 mm | 0.06 T + 0.3 | - |
| Finish B for D > 114.3 mm | 0.05 T + 0.5 | T/6 |
| Finish C | 0.15 | - |
Finish A - Internal and external weld bead not removed
Finish B - External weld bead removed internal weld bead not removed
Finish C - Internal and external weld bead rolled or removed
Finish A shall not be used on HF welded tube
Length
| Type of length | Length L | Tolerance |

| Random | Length range by arrangement | |
| Exact | < 6000 mm | +5/-0 |
| 6000 < L < 12000 | +10/-0 | |
| >12000 | by agreement | |
