How Are Natural Gas Pipelines Cleaned?

In the video above, the reporter discusses a crucial aspect of how the natural gas industry cleans pipelines, focusing on the inline inspection of a custom pipeline using specialized tools known as ” custom pipeline pigs.” This unique pipeline, nearing 60 years of age, is a key asset in the overall management strategy on the natural gas side of the business.

The inspection process involves the use of advanced technology, specifically a tool propelled by compressed air through the pipeline. This tool comprises two essential components: a magnetic flux leakage tool and a caliper tool.

Together, they enable the measurement of corrosion and identification of any dents or deformations in the pipeline. The reporter explains that the smart pig, loaded into the pipeline, plays a crucial role in maintaining the integrity of the infrastructure.

Furthermore, the contractor is shown in the process of preparing the tool, including the battery module, which boasts a sufficient 65 hours of battery life – more than enough for the predicted 12-hour inspection duration. The meticulous preparation, including operating air compressors to propel the tool, reflects the commitment to ensuring the pipeline’s safety and longevity. This inline inspection is a key asset in the overall management strategy for the natural gas side of the business, underscoring the industry’s dedication to proactive maintenance and risk mitigation.
