How to prevent corrosion of seamless steel pipe?

As we all know, seamless steel pipe has better corrosion resistance, is a kind of pipeline resistant to weak acid substances such as steam, and is widely used in our daily life. However, if the seamless pipe is directly placed in a strong alkali or strong acid environment, corrosion will also occur. Therefore, in order to avoid not affecting the use in the later period, it is necessary to do anticorrosion work in advance and maintain it well, so that it can be reasonably applied in production and life.

When we clean seamless steel pipes, whether we use some weak acidic substances for cleaning, we need to pay attention to the content of acidic substances, because if the acidic substances are too strong, it may have a certain impact on our environment, so we It needs to be wiped clean with clean water after cleaning, and do not leave residues on its surface. Some people have a misunderstanding, thinking that since strong acid cannot be used, then strong alkali should be used! However, do not use strong alkaline substances to directly clean the oil stains, because it will make the surface sluggish. The correct way is to just place it in a dry environment, which can reduce corrosion.

In fact, for now, the use of seamless steel pipes is very extensive. Most of them are made of ordinary carbon structural steel, low-alloy structural steel or alloy structural steel by rolling, and are usually used in production and manufacturing.

Why do buried seamless steel pipes need anti-corrosion? Carbon seamless line pipes also need to be anti-corrosion. Buried steel pipes will corrode the outside of the pipes when exposed to water and acidic, saline-alkali soils. Some pipes without anti-corrosion will crack and corrode within a few years, which will directly lead to the outflow of liquid in the pipes, causing environmental pollution and resource loss. It is a kind of loss. 3PE is the external anti-corrosion of the pipeline, and its product materials are three kinds, one is epoxy powder, the other is adhesive, and the third is polyethylene (PE). The service life of this process is 3-5 times that of the steel pipe without anti-corrosion. According to relevant data, the service life is more than 50 years.
