ASTM A106/A53/API 5L Weld Carbon Steel Pipe

The production process of straight seam Welded Pipe is simple, with high production efficiency, low cost, and rapid development. The strength of spiral welded pipes is generally higher than that of straight seam welded pipes. Narrow billets can be used to produce larger diameter welded pipes, and billets of the same width can also be used to produce welded pipes of different diameters. However, compared to straight seam pipes of the same length, the weld length increases by 30-100% and the production speed is lower. Therefore, smaller diameter welded pipes mostly use straight seam welding, while larger diameter welded pipes mostly use spiral welding.Straight seam welded pipes are divided into longitudinal submerged arc welding (LSAW) and electric resistance welding (ERW).
