摘要:
A pipeline pig adapted to be propelled through a pipeline by fluid flowing therethrough wherein the pig has two spaced apart body supporting sections at least one of which has a curved or spherical surface which limits fluid flow past the pig when the pig is traversing a sharp bend (e.g., a 1.5 radius ell) in the pipeline.
