Electric resistance welded (ERW) seam steel tube are frequently used in numerous industrial and household applications and also used in automotive industries. To ensures the acceptability of ERW seam tubes are prepared by various industrial process, the quality of ERW tubes must be evaluated. Drift expanding test is one of the best ways to do so is to examine the quality of tubes. In this paper the authors considered the mechanical properties of various manufacturing processes and different -2 sizes of tubes using drift expanding test. This paper concludes that there is a comparison between the different -2 sizes and standards with a single type of material known as ERW materials they have same composition for all sizes.
