Straight seam steel pipe with outer diameter less than 36mm and special-shaped straight seam steel pipe with section circumference less than 150mm may not be printed. Tips:In case ASTM A53 Grade B in ERW (electric resistance welded) pipe, the weld seam shall be done the heat treatment with a minimum 1000°F [540°C].
But for pipes of the same length, the helical welding seam is 30 to 100% longer than the longitudinal welding seam, thus, the welding cost is higher and the welding efficiency is lower. Therefore, longitudinal welding is more used to produce small diameter pipes, while helical welding is always used for pipes of large diameters. Difference between helical welded pipes and longitudinal Helical Welded Pipes and Longitudinal Welded Pipes. Welded line pipes enjoy a wide acceptance in oil and gas transporting market for its selection variety and relatively low cost. According to the different welding seams, welded line pipes can be further categorized into two types, the helical welded pipes and longitudinal welded pipes.
