Cold Rolled Electric Welded Tubing for Enhanced Strength and Durability Applications

Understanding Cold Rolled Electric Welded Tubing

Cold rolled electric welded (CREW) tubing is a specialized type of steel tube characterized by its unique manufacturing processes and structural benefits. This type of tubing is widely used in various industries due to its durability, versatility, and cost-effectiveness. In this article, we will delve into the characteristics of cold rolled electric welded tubing, its manufacturing process, applications, and advantages.

Manufacturing Process

The production of cold rolled electric welded tubing begins with the creation of a flat steel strip, which is typically sourced from hot rolled steel. The manufacturing process involves several critical steps

1. Clean and Slit the Flat Strip The flat steel strip is cleaned to remove any mill scale or contaminants and then slit into the desired width that corresponds to the final tubing diameter.

2. Forming The slit strip is formed into a cylindrical shape using rollers. The edges of the strip are aligned to prepare for welding.

3. Welding The next step is to weld the edges of the formed tube. Electric resistance welding (ERW) is commonly used in this process. An electric current is applied to the edges, heating the metal until it reaches a plastic state, where the two edges can be fused together. This results in a strong and seamless bond.

4. Cold Rolling After welding, the tube undergoes cold rolling. This process involves passing the welded tube through a series of rollers at room temperature to enhance its structural properties. Cold rolling increases the strength and surface finish of the tubing by refining the metal's grain structure.

5. Finishing Operations Finally, the tubing is cut to length, and additional finishing operations, such as galvanization or painting, may be applied to improve corrosion resistance and overall aesthetics.
