corrosion inhibitor - Newly constructed pipeline

[Sam066]

Hi all,

Is it recommended to run a batch of corrosion inhibitor (oil-based for instance) after hydrostatically testing a pipeline with a water/methanol mixture in case the pipeline commissioning is delayed or a pipeline drying may be sufficient to get rid of the water/methanol mixture?

Thank you,

Sam

Need more detail- how good will this drying be and obviously length and geometry- is there potential for biological activity and thereby corrosion.
If this is a significant pipeline, why is the owner really trusting you alone to handle this most important intermediate stage?

Probably best to close this thread and refer to the same post in pipelines & piping

To cloa (Petroleum)

"how good will this drying be"

That's the question

Then it's down to the installation specification to set the drying acceptance criteria and field monitoring to verify that the criteria have been met.
