Economic losses caused by corrosion

Materials refer to substances that can be used to make useful components, devices or articles. Including metal materials (steel, aluminum, copper, titanium, etc.), inorganic nonmetallic materials (cement, graphite, ceramics, etc.), organic polymer materials (rubber, plastic, fiber, etc.) and composite materials (glass fiber reinforced plastic, carbon fiber, etc.). As long as it is a material, there is a corrosion problem. If we give the phrase "material corrosion" a tense, it will always be "present continuous tense". Don't think that the corrosion of materials has nothing to do with us. The clothes, food, shelter and transportation in our lives are inseparable from materials. Once there is a problem with the corrosion of materials, it will cause economic losses and life-threatening. Corrosion problems are everywhere. The corrosion problems of materials and their products are all over all sectors of China's industry, and they are also related to people's lives. Let's list some cases to see the harm caused by corrosion. Example 1: On October 26th, 2005, the pipeline in the workshop of coking plant of a petrochemical plant in Guangdong suddenly cracked due to long-term corrosion failure, and high-temperature oil and gas sprayed out, which coincided with the inspector's inspection of the pipeline, and the high-temperature oil and gas immediately turned it into ashes, which was terrible! Example 2: In March, 2006, when the civil engineering department of a nuclear power plant carried out the equipment corrosion inspection, it was found that the anchor bolts of the demineralized water tank in the demineralized water distribution system were seriously corroded, and nearly one third of them were corroded. If the corrosion of the anchor bolts and the ground contact corrosion were further aggravated, the stability and earthquake resistance of the equipment would be affected, which would bring serious security risks and affect the safe operation of the power station. Example 3: On the morning of July 22, 2010, the workshop staff of a chemical plant in Guizhou found that the pipeline in the transformation section was leaking, and then organized the company's safety maintenance personnel to check it on the spot, and made a treatment plan. Soon after, a space explosion suddenly occurred at the gas leakage place of the secondary line pipeline of the transformation system, causing 5 deaths and 6 injuries at the scene, and the estimated economic loss was about 5 million yuan. The harm caused by corrosion is various, and most of the corrosion is a "chronic disease" from gradual change to sudden change, which is not easy to attract people's attention, and it will not attract people's attention until it accumulates to a certain extent and becomes a destructive accident. The above few cases remind us that the problem of corrosion cannot be ignored. Dino wax coating has been solving all kinds of corrosion problems for nearly a hundred years and providing one-stop solutions.
