Abstract

Pipe cleaning pigs have a relatively short life expectancy and are ill adapted for cleaning any deposits harder than candle wax. A relatively simple solution to these problems involves a pipe cleaning pig including an elongated, one-piece, flexible, cylindrical body with hemispherical ends annular ribs integral with and extending outwardly from the body, longitudinal ribs extending between the annular ribs for strengthening the annular ribs and defining recesses with such annular ribs, and teeth in the recesses for engaging the interior of a pipe when the pig is moved through the pipe under fluid pressure.
