Will galvanized steel pipe rust?
Time : 2024-11-06
1. First, will galvanized steel pipe rust?
When the steel pipe is exposed to the air, it undergoes oxidation with oxygen or corrosion by oxygen in water to form oxides and rust. Galvanized steel pipe is galvanized, creating a layer of galvanizing to isolate the air, thus making it more corrosion-resistant and less prone to rust. So, will galvanized pipe rust?
Generally speaking, galvanized steel pipe is not easily prone to rust, which does not mean it will never rust. It is merely a matter of time. With prolonged usage, galvanized pipes will rust. Additionally, if the usage environment is relatively humid or experiences prolonged rainfall, etc., galvanized steel pipes will soon exhibit oxidation and spots, and eventually rust.
Furthermore, galvanized steel pipes come in two types: hot-dip galvanized pipes and cold galvanized pipes. Comparatively, hot-dip galvanized pipes are less likely to rust than cold galvanized pipes.
If galvanized pipes are rusty, they can be derusted through certain methods. The main methods for derusting galvanized pipes are as follows:
Firstly, use a solvent to clean the surface of the steel to remove organic matter on the surface.
Then, employ a wire brush and other tools to remove rust, mainly using the wire brush to loosen or tilt rust, welding slag, etc.
Use pickling to clean the galvanized pipe, and the rust on it will be almost removed.
