The corrosion problem of galvanized steel pipe has been a serious problem. Many manufacturers are also due to the increasing cost of corrosion. The direct economic loss caused by light corrosion every year reaches hundreds of millions of yuan, which is a very huge expenditure. Therefore, the corrosivity should be treated in time to recover the economic losses. Why is galvanized steel pipe corroded? These factors are directly related to corrosion. Specifically, let's take a look at the relevant introduction:
Firstly, the influence of external conditions. It mainly depends on the characteristics of the media around the pipeline, temperature, and whether the medium around the pipeline is corrosive. Because the corrosivity of the medium is closely related to the microorganisms contained in the soil. And if it is a long-distance pipeline, the soil environmental properties are more complex. In addition, the temperature of the environment where the pipeline is located will also affect the corrosion of cold drawn seamless steel pipe. If the temperature is higher, the corrosion rate will be accelerated, while the corrosion rate will be slowed down when the temperature is low.
2. Corrosion protection failure. When the pipeline is erected, it is necessary to do a good job in anti-corrosion work or directly use anti-corrosion cold drawn seamless steel pipe. The reason of pipeline corrosion is that the anti-corrosion coating of the pipeline is damaged. Once the anticorrosive coating is separated from the pipe surface, it will naturally cause corrosion protection failure.
