Pipeline Pigging & Cleaning: What Do We Really Know About It?

摘要

Achieving greater solids removal from pipelines with fewer pig runs requires liquid cleaning, also know as chemical cleaning. This method is becoming more popular in the industry. Liquid cleaning in tandem with mechanical pigs will remove a greater volume of debris with fewer cleaning runs. Liquid cleaning by definition means the use of liquid cleaners mixed in a diluent (water, diesel, methanol. IPA, MEK, etc.), forming a cleaning solution pushed through a pipeline using mechanical pigs.
