文摘
- •
Modelled internal pitting corrosion of pipelines using pure birth Markov model
- •
Used close form of negative binomial distribution to estimate future pit depth growth
- •
Pit depth distribution decreases with increase in exposure time of pipelines.
- •
Pitting corrosion damage increases with increased exposure time of pipelines.
- •
Markov predicted future pit depth growth is similar to the field measured pit depth.
