[DANA-IF]

Dear friends ; 

 

I'm wondering if anyone could explain what's the difference between erosion and corrosion in a pipeline ?

 

I'm wondering also if the erosion occurs when we have two phase fluid or it can occur when we have one phase fluid (

 

liquid for example ) ?

 

Thanks a lot !

 

 

Regards !

HI,

 

Erosion is deterioration of material due to high velocity during formation two phase flow in between the single phase process.This Erosion which deteriorates the protective layer and leads to the corosion by consuming ions again.Thats why phase change analysis is important.

Hi ; 

Ok,  the erosion occurs with two phase ( liquid and gas ) due to high velocity , 

 

I think that phenomena is like slugging , doesn't it ?

 

Regards !

Erosion is mechanical damage to a piping section and corrosion is chemical damage to a piping section.  Actually, any fluids flowing through a piping section have some degrees of erosion to the piping.  The higher flow velocity is, the more severe of piping erosion.   The oil/gas industrial acceptable erosion velocity is the function of fluid density per API 14E.

Hello , as per API 14E , they just talk about erosional velocity for Gas/Liquid Two-Phase Lines.
