Usage of spiral steel pipe for anti-corrosion

Due to the corrosion of steel pipelines and equipment, production enterprises have stopped production and the quality of products has deteriorated. It affects the supply of gas, heating steam, or hot water, and brings many difficulties in 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 severe environmental pollution and even caused catastrophic accidents such as fire, explosions, and collapses. Because of the prevalence of metal corrosion. To avoid 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. Expand 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 happens at the joints of steel pipes and the bumps of the pipe itself. The corrosion problem of spiral steel pipes is widespread in all sectors of the national economy and construction, which have brought considerable losses to the national economy. It also caused great difficulties in production and life. Steel pipes are corroded at all times under natural conditions (atmosphere, natural water, soil) or human-made conditions (acid, alkali, salt, and other media). A kind of spontaneous unnecessary consumption. The root cause of the steel pipes is the fact that they are in a thermodynamically unstable state, and under the above conditions, they will return to their original relatively stable state. Produce iron oxide carbonate, and so on. Or turned into soluble ions. This process is the corrosion process of metal. Depending on the statistics, my country's annual steel output is 160 million tons. More than 60 million tons are dropped every year due to corrosion. It is nearly equal to the annual output of the Shanghai Baosteel General Iron and Steel Plant. Corrosion is not just a waste of steel resources but also shortens the service life of pipelines and equipment due to corrosion. The cost of replacing original pipeline equipment far exceeds the price of the metal material itself. Therefore, the production cost increases, reducing the economic benefits directly brought about by corrosion. And the indirect economic losses are enormous. Corrosion products from a scale layer, which affects heat transfer and reduces the efficiency of medium flow rate heat transfer. This dramatically improves energy consumption. The annual economic loss caused by corrosion in China is as high as 280 billion yuan, which is more than the total of natural disasters such as wind disasters, floods, earthquakes, and fire.
