British Petroleum - Scraper Pig Analysis

This ANSYS LS-DYNA analysis demonstrates that a scraper pig, which is used to clean oil and gas pipelines, can negotiate a check valve. The forces generated between the pig and the clapper and between the clapper and the valve body are also evaluated to check the integrity of the assembly. Other analyses also show whether elongated pigs can negotiate wye pieces.
