How to deal with the oxidation and blackening of carbon steel pipe?
After sandblasting, carbon steel pipes develop a surface texture with fine lines and pores, which accelerates oxidation. In high-humidity environments, this process occurs even faster, often leading to surface discoloration, commonly seen in mild steel pipes as well. To prevent oxidation, proper protective measures must be taken after sandblasting. This article will briefly introduce how to deal with the oxidation and blackening of carbon steel pipe.
