Business Description

The processing technology of galvanized steel pipes encompasses pretreatment, electroplating, and post-treatment, each influenced by various factors. Six key factors affecting the quality of electroplated coatings are identified:

Zinc purity affects coating thickness and iron content.
Sodium hydroxide levels impact solution stability and coating quality.
Iron content influences passivation and corrosion resistance.
Polishing methods affect coating brittleness and uniformity.
Temperature alters coating properties and deposition rates.
Cathode movement speed determines coating uniformity and quality.

Galvanized steel pipes undergo electrolysis in zinc solutions, resulting in a uniform zinc coating. Zinc's amphoteric nature and solubility in acids and alkalis facilitate its electrolysis from metal ions. Consideration of these factors during processing ensures the production of high-quality galvanized pipe products. Attention to zinc purity, solution composition, iron content, polishing, temperature control, and cathode movement speed is crucial for achieving uniform, durable coatings with optimal corrosion resistance.
