PIPELINE MAINTENANCE

All in-service pipelines encounter deterioration due to environmental effects. The deterioration is a time-dependent process which makes the structural integrity of pipelines a time variant characteristic. Advanced mathematical methods which employ probability theory need to be used for time-depende

Pipe selection and wall thicknessSteel pipe is required in the majority of oil and gas production and pipeline applications. ASME A53 and A106 and API 5L seamless, electric resistance welding (ERW), and submerged arc welding (SAW) steel pipe are commercially available and most commonly used in pipe
