Abstract
A pipeline pig and pig launching apparatus which allow the automatic launching of multiple pigs into a pipeline are claimed. The pipeline pig comprises an elongate body having first and second ends and a fluid passage defined therein. The fluid passage has an inlet at the first end of the body and an outlet at the second end of the body. At least two support members project radially outwardly from the body and are spaced longitudinally from one another along the body. A valve means is located within the passage and adapted to selectively move between a first position in which fluid is free to flow through the outlet and a second position in which fluid cannot flow through the outlet. A projecting member extends longitudinally from the first end of the body.
