Due to the corrosion of steel pipelines and equipment, the quality of products has been reduced due to the shutdown of production enterprises. It affects the supply of gas, heating steam, or hot water, and brings many difficulties to people's lives. Leakage of buried pipelines and pipelines for oil and gas, water, etc., leaks, leaks, and drips of pipelines and equipment for enterprise refining, chemical, chemical fiber, fertilizer, and pharmaceuticals. In addition to the loss of a large number of useful materials, it also caused serious environmental pollution and even caused catastrophic accidents such as fires, explosions, and collapses. Because of the prevalence of metal corrosion. To prevent or slow down the occurrence of metal corrosion. Various metal anti-corrosion technologies and processes have emerged. The promotion and application of new metal anti-corrosion technology, new materials, and new equipment. Extend the service life of pipeline equipment, save money, and ensure safe production. my country's petrochemical, public utilities, and other industries. The pipeline is perforated 20,000 times per year due to corrosion. It mainly occurs at the joints of steel pipes and bumps on the pipe itself.

The corrosion problem of spiral steel pipes is widespread in all sectors of the national economy and construction, which has brought huge losses to the national economy. It also caused great difficulties in production and life. Steel pipes are corroded all the time under natural conditions (atmosphere, natural water, soil) or man-made conditions (acid, alkali, salt, and other media). Spontaneous wasteful consumption. The root cause of the steel pipes is that they are in a thermodynamically unstable state. Under the above conditions, they will return to their original relatively stable state. Produce iron oxide carbonate and so on. Or converted to soluble ions. This process is the corrosion process of metals. According to statistics, my country's annual steel output is 160 million tons. More than 60 million tons are lost due to corrosion every year.
