Suitable Conditions for Stainless Steel Square Pipe
In the atmosphere, a passive and dense chromium-rich oxide layer is formed on the surface of stainless steel tube to protect the surface, which can prevent further oxidation.
This kind of oxide layer is very thin, through which the natural luster of steel surface can be seen, so that stainless steel has a unique surface.
If the chromium film is destroyed, the chromium in the steel and oxygen in the atmosphere will regenerate the passive film and continue to play a protective role.
In some special circumstances, stainless steel will also appear some local corrosion and failure, but unlike carbon steel, stainless steel will not appear uniform corrosion and failure, so the corrosion margin for stainless steel pipes is meaningless.
Application of Stainless Steel Square Pipe
In industry, stainless square pipes are mainly used for some conveying pipes. Of course, they are more widely used in the construction industry, such as staircase handrails, window guards, railings, road partitions and so on. At present, many products use stainless steel pipes, such as bicycles, medical devices, automobiles and so on.
