The anti-corrosion work of seamless steel tube is closely related to the service life of the pipeline. The editor of seamless steel tube manufacturer will explain to you that the anti-corrosion of buried steel pipe is a key procedure to ensure and prolong its service life, in order to ensure the anti-corrosion insulation layer. It is firmly combined with the pipe wall, and rust removal of the pipe is the most critical.

Generally, the rust on the surface of American standard steel pipes can be divided into floating rust, medium rust and heavy rust according to the factory time, storage and transportation conditions, and the degree of climatic humidity.
Floating rust: The Chinese manufacturer of seamless steel tube tells you that when the factory date is short and stored outside the open air, there is only a small amount of thin rust on the surface of the tube. Manual operations such as steel wire brush, sandpaper and cotton yarn can reveal the metallic luster.
Medium rust and heavy rust: The Chinese manufacturer of seamless steel tube tells you that when the delivery date is long and when it is stored in the open air or repeatedly transported and the transportation is long, the surface of the pipe will appear oxidized and rusted, and the rust spots will be heavier.
Seamless steel tube Chinese factory wholesale manufacturers tell you that severely rusted pipes are not suitable for sub-water delivery systems. For medium-rust pipes and large batches, you can use rust remover or mechanical sandblasting to remove rust mechanically, which can increase labor. Efficiency, reduce pollution to people and air.
The seamless steel tube Chinese factory wholesale manufacturer tells you that when high anti-corrosion quality is required or the inner and outer walls of the pipe are rusted, chemical rust removal methods can be used to effectively remove the oxides on the inner and outer surfaces of the pipe.
No matter which method is used to remove rust, the anti-corrosion layer should be treated immediately after rust removal to avoid oxidation and corrosion by air again.
