I was reading the design basis of the factory working there and I encountered the following Sentence :
... the design life of the pipeline is 25 years.
and also I know that corrosion inhibitor is injected to the pipeline continuously.
One of the my colleague says that corrosion inhibitor injection has not any credit to lifetime of pipeline and without the injection the pipeline lifetime should be 25 years. Of course he said that this subject is applicable for any pipeline. Is He right? the pipeline is 10 km sour crude oil with 50 barg pressure.
Thanks in advance.
