Local pitting corrosion. It refers to a form of corrosion damage that occurs in part of the metal surface of DIN 1630 ST52.4 seamless steel pipe. After the occurrence of crevice corrosion, it can develop rapidly to a deep trend, through DIN 1630 ST52.4 seamless steel pipe. Pitting corrosion is very harmful, especially for various high-pressure vessels. After corrosion occurs, it should be polished or painted immediately to prevent further corrosion of DIN 1630 ST52.4 seamless steel pipe.
Symmetrical corrosion. This means that all DIN 1630 ST52.4 seamless steel pipe pipelines exposed to corrosive natural environments will undergo chemical changes and suffer symmetrical corrosion. This type of corrosion can accurately measure its corrosion rate and predict and analyze its corrosion level.
Therefore, in many types of corrosion, the corrosion level of symmetrical corrosion is generally measured and predicted and analyzed based on the quality of DIN 1630 ST52.4 seamless steel pipe and the thickness reduction of DIN 1630 ST52.4 seamless steel pipe. Outside of the unique natural environment, the symmetrical corrosion rate of DIN 1630 ST52.4 seamless steel pipe is very low, the service life is long, and the maintenance is low-cost.
