Corrosion Coupons and Probes required ?
Corrosion Coupons and Probes required ?
(OP)
Our client has a non-corrosive fluid (NGL) pipeline. There is no chemical injection in the upstream of pipeline.
1) DO we still need corrosion probes/coupons on the pipeline when it goes underground and comes above ground ?
2) As I understand, coupons are generally used if there is any chemical injection in the stream ?
3) Also if the fluid is corrosive, no chemical injection, do we need corrosion coupons in that case ?
