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