Considerations in the Internal Corrosion Mitigation

Corrosion is an important dominant contributing factor to failures and leaks in pipelines. It´s important that to deal with this issue, there is recommended practices to improve and maintain the mechanical integrity of upstream pipelines. They are intended to assist ups tream oil and gas producers in recognizing the conditions that contribute to pipeline corrosion incidents, and identify effective measures that can be taken to reduce the likelihood of corrosion incidents. These factors could be low velocity and poor pigging practices allow water to stagnate in the pipelines, CO2 dissolves in water to form carbonic acid, Corrosion rates increase with increasing CO2 partial pressures for example. This document addresses design, maintenance and operating considerations for the mitigation of internal corrosion in oil pipeline systems.
