Abstract
A pipe scraper for removing a uniform amount of material from the perimeter of a pipe. The pipe scraper has a shoulder and biased members for urging the pipe against an interior surface of the scraper body to achieve a uniform scrape with both round and oval pipes, without a need for blade adjustment. Uneven scraping due to canting of the pipe with respect to the body is also eliminated.
