Abstract
The present disclosure sets forth a pipeline pig which is formed of two primary dimensions and two primary components. It is made with a set of N disks where N is preferably 6, 7, or 8 and the disks are all provided with a common thickness and common diameter. The thickness is about 10% of the pipe ID while the diameter is about 105% to about 110% of pipe ID. The excess size enables wiping of the inside surface of the pipeline. Importantly, when the disks are folded back, they are spaced sufficiently along the pig so that folded back disks each individually flatten and do not overlap so that folded disks are doubled; this avoids building up the diameter excessively during transition through a small ID opening.
