Abstract
An improved cup for use as a part of a pipeline pig is in the form of an elastomeric cup member having an outer circumferential pipe engaging portion defined by a plurality of at least three closely spaced apart integral circumferential lip portions, the lip portions being separately flexible with respect to each other and each of the lip portions having a length that is at least twice its thickness. The multiple-lip cup may be removably attached to a pipeline pig body or be made integral with an elastomeric pipe pig body.
