201 stainless steel pipe pitting causes of 201 stainless steel pipe profiles due to the formation of dense chromium oxide film with high resistance to erosion. However, localized spot erosion is hard to avoid.
Pitting crushing has a very large hidden and unexpected, especially in the petroleum, chemical, nuclear and other areas, pitting easily lead to perforation of the wall, so that a large amount of oil and gas leaks, and even cause fire, explosion and other disasters .
Ma Xiu-liang and other scientists have shown that the localized melting of manganese sulfide is originated from the interface between it and "tumor" under the necessary conditions of the medium, and thus gradually expands to the body of the material.
In essence, the team teamed up with Hu Peijun of the Queen's University in Belfast, UK, to identify oxide octahedrons that have strong activity and easily fuse rapidly around them with metallic ions as their Characteristics of the general situation.
Similar to "malignant tumors"; on the contrary, the less active nano-octahedrons use oxygen ions as their external profiles, similar to "benign tumors."
