Factors that can cause corrosion of galvanized steel pipes
What factors can cause corrosion of galvanized steel pipes
The surface quality, appearance, and dimensional accuracy of galvanized steel pipes are better than those of hot-rolled plates, and the product thickness is reduced to about 0.18mm, so it is favored by the majority of users.
The corrosion problem of cold-drawn seamless steel pipes is already a serious problem. Many manufacturers are also increasing the cost of corrosion. The direct economic losses caused by light corrosion reach hundreds of millions of yuan every year. It's a very huge expense. Therefore, corrosiveness should be dealt with in time to recover economic losses. Why does cold drawn seamless steel pipe corrode? These factors may be directly related to corrosion. Specifically, let's take a look at the relevant introduction directly:
1. The influence of external conditions. The main thing is to first look at the characteristics and temperature of the medium around the pipeline, and whether the medium around the pipeline is corrosive. Because the corrosiveness of the medium is closely related to the microorganisms contained in the soil. And if it is a long-distance pipeline, the soil environment will be more complex. In addition, the temperature of the environment in which the pipeline is located will also affect the corrosion of cold-drawn seamless steel pipes. If the temperature is higher, the corrosion rate will be accelerated, while at lower temperatures, the corrosion rate will be slower.
2. It means anti-corrosion failure. When erecting the pipeline, anti-corrosion work must be done or anti-corrosion cold-drawn seamless steel pipes must be used directly. The reason why the pipeline is corroded is because the anti-corrosion layer of the pipeline has been damaged. Once the anti-corrosion layer and the pipe surface are separated, the anti-corrosion failure will naturally occur.
