What Does Pipeline Corrosion Control Mean?
Pipeline corrosion control is the process and scientific method of limiting pipeline corrosion. Several different corrosion control methods are used as part of an overall pipeline corrosion control plan. Generally, all pipeline owners and operators have a pipeline corrosion control plan.
Corrosionpedia Explains Pipeline Corrosion Control
Pipeline corrosion control is an incredibly important practice for pipeline owners and operators. The lack of a pipeline corrosion control plan can result in devastating pipeline failures with dangers to the environment and humans. Many governing agencies and industry groups require pipeline owners and operators to have a well-documented pipeline corrosion control plan to mitigate these risks.
Pipeline corrosion control involves the use of several different corrosion-limiting methods. A popular method is cathodic protection, which involves saving the pipeline material from corrosion by making it the cathode in an electrolytic cell. This can be done by attaching a more reactive, sacrificial anode to the pipeline or by running electrical currents through the pipeline material.
Coating repair and additional coatings may also be applied as part of a corrosion control plan. Pigging, or the internal cleaning of the pipeline, and periodic inspections are also used to control pipeline corrosion. All of these methods must be documented in the pipeline corrosion control plan.
