 Course Overview


corrosion courses: pipeline internal corrosion, pipeline integrity assessmentCorrosion is a dominant contributing factor to failures and leaks in pipelines. The high cost of corrosion and corrosion control in multiphase (oil, gas, and brine) pipelines represents
a significant operating expense for the field. Corrosion severely affects pipeline operations, leading to lost production, unscheduled downtime for maintenance or repair, and even catastrophic failure that impacts health, environment, and safety. Maintaining the ageing infrastructure such as underground pipelines is always a challenge to facility owners worldwide. This 5-day course covers internal pipeline corrosion, inline inspection and assessment methodology, and pigging technology. A practical field guide for investigating internal corrosion of pipelines is also presented.


This course is available for in-house training, online and distance learning worldwide. It can also be customized to meet the specific needs of your organization.
