A crude oil tower with a carbon steel overhead pipeline has been shut down due to an accident. On inspection, it has been found that some sections of the pipeline have a maximum thickness of 0.21 in, while other sections have a thickness of up to 0.24 in. Once the investigation is completed, another shutdown for inspection is scheduled to take place in two years’ time. a) Noting that the required minimum thickness of the pipe is 0.15 in and the current corrosion rate is 40 mils/year, calculate the required thickness the pipe presently needs to be so that it is compliant at the next scheduled inspection. b) Based on your answer, what conclusion can you draw regarding the pipe? c) Make a recommendation to proceed in relation to this pipeline.

A crude oil tower with a carbon steel overhead pipeline has been shut down due to an accident.
On inspection, it has been found that some sections of the pipeline have a maximum thickness of 0.21 in, while other sections have a thickness of up to 0.24 in.
Once the investigation is completed, another shutdown for inspection is scheduled to take place in two years’ time.
a) Noting that the required minimum thickness of the pipe is 0.15 in and the current corrosion rate is 40 mils/year, calculate the required thickness the pipe presently needs to be so that it is compliant at the next scheduled inspection. b) Based on your answer, what conclusion can you draw regarding the pipe? c) Make a recommendation to proceed in relation to this pipeline. |
