Manufacturing Process of Electric Resistance Welded Tubes

The manufacturing of ERW tubes involves several critical stages, each contributing to the overall quality and performance of the final product.

1. Material Preparation

The process begins with the selection of high-quality steel coils, which are the primary raw material for ERW tubes.

Material Selection: The choice of steel type (e.g., carbon steel, stainless steel) is based on the intended application. Buyers should ensure that suppliers provide materials that meet relevant industry standards such as ASTM, EN, or API.
Surface Treatment: The steel coils undergo surface preparation to remove any contaminants like rust, oil, or scale, ensuring a clean surface for welding.

2. Forming

In this stage, the prepared steel strips are shaped into a tubular form.

Roll Forming: The steel strip is passed through a series of rollers that gradually bend it into a circular shape.
Welding: The edges of the rolled strip are brought together and welded using electric resistance. This method employs high-frequency electrical currents to generate heat at the seam, allowing the edges to fuse without the need for additional filler materials. There are two primary forming techniques:
Hot Forming: Involves heating the strip before welding, which can enhance the mechanical properties of the tube.
Cold Forming: This method is preferred for its ability to produce tighter tolerances and smoother finishes.

3. Assembly

Once the tube is formed and welded, additional processes may be employed to enhance its properties.

Sizing: The tube is passed through sizing mills to ensure it meets the specified dimensions.
Cutting: Tubes are cut to the required lengths, which may vary based on customer specifications.

4. Finishing

The final stage of manufacturing involves surface finishing and additional treatments.

Heat Treatment: Depending on the specifications, tubes may undergo processes like annealing to relieve stresses and improve ductility.
Surface Finishing: The outer surface of the tube may be treated through processes such as pickling, passivation, or polishing to enhance corrosion resistance and aesthetic appeal.
