Introduction to Common Issues with Anti-Corrosion Steel Pipe Coating Materials

Common issues can be categorized into three types: uneven coating, dripping of the anti-corrosive agent, and bubbling of the anti-corrosive agent.

(1) Uneven Coating: This issue occurs when the anti-corrosive agent is unevenly distributed on the steel pipe surface. Some areas have a coating that is too thick, leading to waste, while other areas are too thin or not coated at all, reducing the pipe's anti-corrosion ability and leading to rust.

(2) Dripping of the Anti-Corrosive Agent: This happens when the anti-corrosive agent solidifies on the steel pipe surface like water droplets. While it does not directly impact corrosion resistance, it affects the pipe's appearance, making it look dull and uneven.

(3) Bubbling of the Anti-Corrosive Agent: Air trapped in the anti-corrosive agent forms bubbles of various sizes on the steel pipe coating. Larger bubbles can be easily popped, compromising the coating's thickness and reducing its anti-corrosion capability, which leads to rust at the affected areas.
