Seamless steel pipes inevitably develop rust on their surface over time. Once a steel pipe rusts, it means its life span will be shortened. If you are being troubled by this problem. Wanzhi Steel, as a professional seamless pipe manufacturer and supplier, will help you to learn more about preventing rusting of seamless steel pipe.
Solvents and emulsions can be used to remove oil, grease, dust, lubricants, and similar organic substances. However, this does not remove rust, fluxes, etc. from the surface of seamless tubes.
By doing pickling treatment with both chemical cleaning and electrolysis, we can remove scale, rust, and old coating from the surface of seamless steel pipes.
Tools for Rust Removal
The surface of the steel pipe is polished using wire brushes etc. to remove scale, rust, weld slag, etc. Hand tools can remove rust up to Sa2 level, while power tools can remove rust up to Sa3 level.
Jet rust removal is done by high-power motors driving the jet blades to rotate at high speed so that abrasives such as steel shot, steel sand, wire segments, and minerals are jetted on the surface of seamless steel pipes under strong force. This method can completely remove oxides.
Seamless steel pipe will inevitably rust after long-term use. If your seamless steel pipe is used in a humid environment, then it will rust even faster. At this point, you may wonder what can be done to slow down the rate of rusting. Wanzhi Steel tells you that galvanizing seamless steel pipe is a good way.
1. Hot-dip galvanized
2. Cold galvanized
Hot-dip galvanizing is done by pickling the steel pipe first, removing the iron oxide on the surface of the pipe, and then feeding it into a hot-dip plating bath. In addition, hot-dip galvanizing has the advantages of uniform plating, strong adhesion, and long service life. The zinc consumption of cold-galvanizing is 60%-75% lower than that of hot-dip galvanizing. And the former has a lower zinc layer thickness than the latter. In addition, cold-galvanizing is not as protective as hot-dip galvanizing in terms of corrosion protection.
Applications: cold-galvanizing is generally used in less corrosive applications. While hot-dip galvanizing is used for outdoor applications with high corrosion resistance.
Seamless steel pipes are increasingly reused as affordable steel pipes and thus are used in large numbers in different fields. In addition, this kind of steel pipe is often used in our homes, such as stainless steel seamless steel pipe used as drinking water transmission pipe. Although stainless steel seamless pipes are not prone to corrosion, care and maintenance should be taken.
1. Try to install in a clean environment
2. Check and clean regularly
3. Prohibit contact between steel pipe and corrosive substances
Wanzhi Steel reminds you that paying attention to the maintenance of your seamless steel pipes will make them last longer. This also means that it will save you a lot of extra money.
