Stainless steel elbow pipe is required to use the environment, and it needs to be cleaned regularly to remove dust and keep it clean and dry.
Stainless steel is not "stainless"
SUS304 stainless steel elbow pipe belongs to the steel pipe of the United States brand. The domestic brand is equivalent to 0Cr19Ni9 stainless steel tube, which is usually replaced by 0Cr18Ni9.
Corrosion prevention mechanism of stainless steel elbow pipes is that the alloy elements form a compact oxide film, which insulates oxygen contact and prevents further oxidation.
So stainless steel is not "stainless."
There may be several reasons for the occurrence of rust in the 304 materials:
Chlorine ions are present in the environment.
Chlorine ions are widespread, such as salt, sweat, sea water, wind, soil, and so on.
Stainless steel in the presence of chlorine ion in the environment, corrosion quickly, even more than ordinary low carbon steel.
Therefore, the use of stainless steel elbow pipe fittings is required, and it needs to be cleaned regularly to remove dust and keep it clean and dry.
With the development of social economy, the application of stainless steel tube has been widely popularized.
It will bring a whole new change in every field.
The theoretical weight of stainless steel elbow pipe: W= outer diameter - wall thickness x - wall thickness x0.02491 stainless steel tube - the outer diameter - wall thickness x - wall thickness x0.02491.
