We also need to do a good job of anti-corrosion in the storage of seamless stainless steel pipes. Among them, there are many corrosion hazards of seamless stainless steel pipes. We also need to know some of the more common points. We also need to do it correctly in use. The following What are the hazards of corrosion of seamless stainless steel pipes?
According to statistics, about one-third of 304 stainless steel pipes are discarded due to corrosion in use, and two-thirds of them can be regenerated. It can be seen that about 1/9 or 10% of the 304 stainless steel pipes obtained by smelting cannot be recovered due to corrosion damage. In production and life, about 90% of the metals we come into contact with are steel. The current annual output of steel in my country is 40 million tons, and 13 million tons of steel products are discarded every year, of which about 4 million tons cannot be returned to the furnace.
In fact, the loss and harm caused by the corrosion of 304 stainless steel pipe are not only the damage of the stainless steel material and the product itself. Corrosion-increased equipment manufacturing, maintenance costs, equipment and pipeline leakage, product contamination, local and global shutdowns, combustion and explosion accidents, etc., cause even more staggering losses and hazards. Many chemical equipment, aircraft, automobiles and ships made of stainless steel cost far more to manufacture than the value of the material itself.
Corrosion has brought great losses to the national economy of various countries, but people have not fully understood it for a long time. In the past 40 years, many countries have conducted scientific investigations and calculations on the losses caused by corrosion, and the results (see Table 1) have shocked people. The direct economic losses caused by corrosion account for more than 1 to 4% of the gross national product. The above is a summary of the hazards of corrosion of seamless stainless steel pipes.
