- High-Frequency Electric Resistance Welding (ERW) In this method, electrical currents are passed through the edges of the metal strips to heat them, allowing them to fuse together under pressure. This technique is highly efficient and produces a continuous weld along the length of the pipe.
Welded line pipes offer several advantages over other types of pipes, such as seamless pipes. One of the primary benefits is their cost-effectiveness. The manufacturing process of welded pipes is relatively straightforward, which helps reduce production costs. Additionally, welded line pipes can be produced in large quantities, making them more readily available for various projects.
