Analysis of pipeline corrosion

    There are two main types of pipeline corrosion: internal corrosion and external corrosion.

    External corrosion is mainly due to the corrosion caused by the connection of the pipeline material with the external environment such as soil, seawater, atmosphere and other corrosive media. At the same time, because some pipelines have an insulation layer outside, moisture may be caused under the insulation layer due to other factors Accumulation (sometimes because of the high temperature of the medium in the pipe causes the external moisture to heat up) causes highly corrosive corrosion areas that cause corrosion under the insulation layer of the pipeline.

    Internal corrosion is different depending on the nature of the fluid in the pipeline. Including acidic corrosion, corrosion caused by chloride ions, microbial corrosion, stress corrosion, welding corrosion, etc.
