Analysis of pipeline corrosion

Update:2020-07-24   View(s):783   Keywords :pipeline

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 with 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) causes highly corrosive corrosion areas, which can cause corrosion under the insulation layer of the pipeline.

 

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