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

Seamless pipe supplier tells you that 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 time of delivery, storage and transportation conditions, and humidity.
Floating rust: The Seamless pipe supplier tells you that generally when the factory date is short and when it is not stored in the open air, there is only a small amount of thin rust on the surface of the pipe. Manual operations such as steel wire brush, sandpaper and cotton yarn can be used to reveal the metallic luster.
Medium rust and heavy rust: The Seamless pipe supplier tells you that when the delivery date is long and when it is stored in the open air or multiple transports and the transportation is long, the surface of the pipe will be oxidized and rusted, the rust spots will be heavier, and the scale will fall off in severe cases.
Seamless pipe supplier tells you that severely rusted pipes are not suitable for sub-water delivery systems. For medium rust pipes and large batches, you can use rust removers or mechanical sandblasting methods to remove rust, which can improve labor efficiency and reduce damage. Pollution of people and air.
Seamless pipe supplier tells you that when high anti-corrosion quality is required or the inner and outer walls of the pipe are corroded, chemical rust removal methods can be used to effectively remove oxides on the inner and outer surfaces of the pipe.
Seamless pipe supplier tells you that no matter which method is used to remove rust, it should be treated with anti-corrosion layer immediately after rust removal to avoid oxidation and corrosion by air again.
