Many people think that stainless steel 304 pipes will not rust. In fact, stainless steel pipe has good corrosion resistance. The reason is that the surface forms a passivation film, which exists in nature in the form of a more stable oxide. In other words, although the stainless steel tube, according to the use of different conditions, the degree of oxidation is not the same, but ultimately they are oxidized. This phenomenon is usually called corrosion.
In the daily welding and processing process, in order to protect our stainless steel pipe, we should try to avoid the cutting iron sparks and friction with iron and other things.
In using stainless steel 304 pipes, be careful not to contact with all kinds of things containing acid, such as sulfuric acid, nitric acid, etc. Organic acids are also not allowed. Usually we use a lot of debris, and should be careful to avoid contact with cement and lime, to minimize debris pollution.
In the cleaning process, we need also to avoid cleaning with sewage and cleaning essence. These are generally for the internal stainless steel tube precautions. For the use of the external stainless steel pipe, you should generally flush twice a year. The external stainless steel 304 pipes generally has the effect of rain flushing. And manual cleaning is also combined with rain flushing. Manual cleaning uses a sponge with soapy water to clean. Generally speaking, for the surface of the stainless steel tube, the combination of rain flushing and manual cleaning has a good effect of dust removal, which can maintain the surface of the stainless steel tube bright.
