When we use the alloy steel pipe for some time, we will find some brown substance covering on the steel pipe surface, which is described steel pipe rusted, there are many reasons to cause rusty steel tube, today we give brief introduction of the main three reasons.
First, the selection problem, steel pipe is made of single steel material, material melted in the melting pot, in the production process to add some alloying elements, then form the mode of steel pipe, if we ignore the rusty detail in the choice of material, anti-rust capacity is relatively weak.
Second, the environmental reasons, it is mainly because the use of the process, alloy steel tube space filled with a lot of rusty steel pipe easily lead to gas or a solution, so that the occurrence of steel pipe corrosion phenomenon.
Third, other reasons, maybe the course of transportation, steel pipe surface soaked by rain. Perhaps in the installation process, it was eroded by corrosive substance. To prevent this phenomenon, transport or stack steel pipe also pay attention.
