Abstract

A pipeline pig has hollow flared ends 16 and a central portion 14 of smaller radial dimension than adjacent parts of the pig. Detachable appendages 32 extend radially outward from the pig in circumferential rows. At least one row of appendages 32 is in the central portion 14 and the appendages extend radially outward less than the other rows of appendages. The appendages are threaded into sleeves 34 having anchored bases 36.
The row of appendages that extends radially outward by a smaller amount than the other appendages is subjected to reduced wear, but when the pig encounters resistance, the central part of the pig extends outward bringing the appendages into contact with the interior of the pipeline.
