What type of cleaning plug is made with hardened steel or silicon carbide wire brushes?

The correct answer is that a scraping pig is specifically designed to use hardened steel or silicon carbide wire brushes for cleaning pipelines. These brushes are effective at removing stubborn debris, scale, or corrosion that accumulates on the interior walls of the pipeline. The design and material of the brushes allow them to scrub surfaces aggressively without deforming, making them particularly suited for tough cleaning tasks.

Scraping pigs are predominantly used in situations where a high degree of cleanliness is required, such as in oil and gas pipelines or other industrial applications where maintaining flow efficiency is crucial. Their construction is tailored for durability and effectiveness in rigorous conditions, which is why hardened steel or silicon carbide is chosen for the brushes.

Understanding this type of cleaning methodology is vital for maintenance operations within distribution systems. Regular cleaning of pipelines with effective tools like scraping pigs helps in preventing flow restrictions, ensuring safety, and extending the life of the pipeline system.
