Welded Tubes

Piyush Steel 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
