Comparison Submerged Arc Welded (SAW) Pipes With ERW Pipes
Two widely recognized types of pipes in the industry are Submerged Arc Welded (SAW) pipes and Electric Resistance Welded (ERW) pipes . Although both serve essential roles in various applications, their manufacturing processes and properties diverge significantly. This article provides a comprehensive comparison between ERW pipes and SAW pipes, focusing on key aspects such as welding speed, weld quality, and applications. Welding Speed: ERW welding is a high-speed process, whereas SAW welding is slower and more controlled. Weld Quality: The instantaneous nature of high-frequency welding makes it more challenging to ensure consistent weld quality compared to the slower and more controlled SAW process. Applications: ERW pipes are typically used for medium to low-pressure applications, such as water and gas transportation, while SAW pipes are preferred for high-pressure and large-diameter applications, such as long-distance pipelines. In summary, both ERW pipes and SAW ...
