Spiral steel pipe for anti-corrosion purposes

Due to the corrosion of steel pipes and equipment, production enterprises have stopped production, and production quality has declined. Affect domestic gas supply, heating steam or hot water, and bring many difficulties to people’s life. Leakage of buried oil, gas, water, and other pipelines and pipe networks, run, leak, and drip of enterprise oil refining, chemical, chemical fiber, chemical fertilizer, pharmaceutical, and other pipelines and equipment. In addition to losing a large number of useful materials, it also causes serious environmental pollution, and even causes catastrophic accidents such as fire, explosion, and collapse. 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 as the times require. Popularization and application of new technology, new materials, and new equipment for metal anti-corrosion. 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 due to corrosion up to 20,000 times per year. It mainly occurs at the interface of the steel pipe and the bump damage of the pipe itself.

Corrosion of spiral steel pipes generally exists in various sectors of the national economy and construction, which has brought huge losses to the national economy. It also causes great difficulties in production and life. Steel pipes are corroded all the time under natural conditions (atmosphere, natural water body, soil) or artificial conditions (acid, alkali, salt, and other media). A senseless waste that goes on spontaneously. The fundamental reason is that steel pipes are in a thermodynamically unstable state, and they will return to their original relatively stable state under the above conditions. Generate iron oxide carbonate and so on. Or 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 due to corrosion every year. Almost equal to the annual output of Shanghai Baosteel General 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, which increases production costs and reduces the direct economic benefits caused by corrosion. And the indirect economic loss is 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 higher than the sum of natural disasters such as wind disasters, floods, earthquakes, and fires every year. Also anti-corrosion spiral steel pipe!
