The Manufacturing Process of Chrome Tube

1. Surface Preparation

The first step is cleaning the iron pipe to remove dirt, grease, and rust. This is done through degreasing (using alkaline solutions) and pickling (immersing in acid to eliminate oxides). A thorough rinse with water follows to neutralize any residual chemicals.

2. Electro-plating Setup

The cleaned pipe is immersed in an electrolyte solution containing dissolved metal ions (typically zinc or nickel). It acts as the cathode, while the plating metal serves as the anode. A direct current (DC) is applied, initiating the electroplating reaction.

3. Electro-plating Process

Under electrical current, metal ions from the solution deposit onto the iron pipe, forming a uniform metallic coating. The thickness of the plating depends on factors like current density, plating time, and solution composition.

4. Post-Treatment

After plating, the pipe undergoes rinsing to remove excess chemicals. It may then be passivated (treated with a chromate solution) to enhance corrosion resistance. Finally, the pipe is dried to prevent water spots.

5. Quality Inspection

The finished product is checked for coating thickness, adhesion, and defects using methods like salt spray testing or visual inspection.

This process ensures that electroplated iron pipes meet industry standards for durability and performance.
