From Steel Strip to Cylindrical Shape

The journey from a flat strip steel strip to a cylindrical pipe involves several stages:

  1. The flat strip is fed into the forming rolls machine.
  2. It is shaped into a cylinder by a series of rollers.
  3. High-frequency electrical currents are used to weld the edges of the flat steel strips, facilitating their transformation into cylindrical shapes.

This stage is critical as it ensures that the steel strip is accurately formed and prepared for the subsequent welding process. The precision in forming the steel strip into a cylindrical shape ensures that the final ERW tube meets the required specifications and standards.

High-Frequency Welding and Weld Seam Creation

High-frequency welding is a cornerstone of the ERW tube production process. This method uses induction heating to bond the edges of the steel strip, resulting in a strong and durable weld seam. Modern advancements in ERW technology, such as the transition to High-Frequency Welding (HFW), have further enhanced weld integrity and overall pipe performance. The application of high-frequency electrical resistance ensures that the steel strip edges are effectively welded together.

After high-frequency welding, any burrs outside the weld seam are typically removed to ensure a smooth finish. This precision in the welding process allows ERW tube mills to produce tubes with tight tolerances, increasing material yield and reducing waste.

Cooling, Sizing, and Cutting

Post-welding, the pipes undergo the following steps:

  • Cooling process to ensure quality and reduce residual stresses
  • Stabilization of the material to prepare it for further processing
  • Resizing to meet exact specifications, ensuring that the process begins for market demands

The pipes are then cut to the required lengths for distribution and use in various applications. This final step ensures that the pipes are prepared for their intended use, maintaining the high standards expected from ERW tube mills.
