How is the corrosion margin of pipelines determined?
Thread Content
I would like to ask the experts: how is the corrosion margin for pipelines determined? In other words, how is value C2 calculated according to the \"Code for Design of Industrial Metal Pipelines (2008 Edition)\」(GB 50316-2000)? Should corrosion and wear of the fluid medium inside the pipeline, as well as the corrosion of the pipeline’s outer wall caused by the external environment, be taken into consideration? Which domestic regulations currently specify this calculation? Thank you all
Pipeline service life divided by annual material corrosion rate
Generally, 1.5 for carbon steel, 0 for stainless steel
