What are the reasons for corrosion of seamless steel pipe?

Seamless steel pipe is a stainless steel material products, generally will not rust. But when there are high strength corrosive chemical agents, there will still be a small part of corrosion. The reasons for the corrosion of seamless steel pipe are nothing more than the following:

1. seamless steel tube spot corrosion: is a kind of local corrosion form leading to corrosion.
2. intergranular corrosion: grain boundary is the boundary city of disordered dislocation between grains with different crystallographic orientations.
3. crevice corrosion: is a form of local corrosion, it may be all in the solution stagnation of the gap or the surface of the shielding.
4. Corrosion: a term used to describe the corrosion phenomenon occurring on the entire surface of the alloy in a relatively uniform manner.
