BS1387 welded/ERW steel pipe

BS1387 ERW STEEL TUBE. ERW steel tube is formed by rolling strip and welding the seam, with tighter dimensional tolerances and less weight. The weld seam is heat treated after welding that no untempered martensite remains, and the weld flash can be removed from both inner and outer surfaces. For low pressure fluid (water, oil, gas and other liquid ) transmission in oil and gas industry.
