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.
Claims5
A pig for use in a pipeline comprising onepiece, elongated, flexible, cylindrical body means;
- a plurality of annular rib means integral with said body means;
- longitudinal rib means integral with said body means extending between adjacent said annular rib means and defining recesses with said annular rib means;
- and tooth means extending out of said body means in each said recess, said tooth means and said rib means simultaneously engaging the interior of a pipeline when the pig is moved through the pipeline by a pressure differential in the pipeline.
