What is the scraping tool called that is forced through a pipeline to remove accumulations of wax and debris from the walls?

• A. Bore
• B. Pig
• C. Dredge
• D. Scraper

Answer: (B)

In pipeline maintenance, the device used to clean the interior by scraping wax and debris is called a pig. Pigs are pushed or propelled through the pipe, often with brushes or other scraping elements, to scrub the walls and carry dislodged material to a reception point. They’re specifically designed for cleaning and sometimes inspection, making them the standard term in this context. Bore describes the diameter or the act of drilling, not a cleaning tool. Dredge is used for removing sediment from bodies of water, not pipelines. Scraper is a general term and doesn’t name the common cleaning device used in pipelines. So the best fit for this purpose is the pig.
