The use of spiral steel pipes for anti-corrosion

Due to the corrosion of steel pipelines and equipment, production companies have stopped production and the quality of products has declined. It affects the domestic gas supply, heating steam, or hot water supply, and brings many difficulties to people’s lives. Leakage of buried oil, gas, water, and other pipelines and pipe networks, enterprise oil refining, chemical, chemical fiber, fertilizer, pharmaceutical, and other pipelines and equipment running, leaking, and dripping. In addition to losing a large amount of useful materials, it also causes serious environmental pollution, and even causes catastrophic accidents such as fires, explosions, and collapses. Given the ubiquity of metal corrosion. To prevent or slow down the occurrence of metal corrosion. Various metal anti-corrosion technologies and processes have emerged. Promotion and application of new metal anti-corrosion processes, 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. Pipelines are perforated 20,000 times per year due to corrosion. It mainly occurs at the interface of the steel pipe and the bumps on the pipe itself.

The corrosion problem of spiral steel pipes is prevalent in all sectors of the national economy and construction, causing huge losses to the national economy. It also causes great difficulties in production and life. Steel pipes corrode all the time under natural conditions (atmosphere, natural water, soil) or man-made conditions (acid, alkali, salt, and other media). A spontaneous and unnecessary consumption. The fundamental reason is that steel pipelines are in a thermodynamically unstable state. Under the above conditions, they will return to their original relatively stable state. Generate iron oxide carbonate, etc. Or converted into soluble ions. This process is the corrosion process of metal. According to statistics, my country’s annual steel output is 160 million tons. More than 60 million tons are lost every year due to corrosion. It is almost equal to the annual output of Shanghai Baosteel Iron and Steel Plant. Corrosion is not only a waste of steel resources but also shortens the service life of pipelines and equipment due to corrosion. The cost of replacing new pipeline equipment far exceeds the price of the metal material itself, thus increasing production costs and reducing economic benefits. Direct economic benefits are caused by corrosion And the indirect economic losses are huge. Corrosion products form a scale layer, which affects heat transfer and medium flow rate, reduces heat transfer efficiency, and greatly increases energy consumption. The annual economic loss caused by corrosion in my country is as high as 280 billion yuan, which is more than the total annual wind disasters, floods, earthquakes, fires, and other natural disasters combined. Also anti-corrosion spiral steel pipe!
