Abstract: A pipeline pigging element (10) that changes its size in an axial and a radial direction as a function of applied pipeline pressure. The pigging element includes at least two circumferential zones (13, 15) having different section modulus than one another, each of the zones changing at different rates from one another between an uninflated and an inflated state at the applied pipeline pressure. The pigging element reacts to changes in pipe geometry, having a first length and a first diameter at a first applied pipeline pressure and a second length and a second diameter different than the first at a second applied pipeline pressure. As the pigging element wears, it becomes easier to inflate at the applied pressure and sealing contact with the pipe wall remains substantially unaffected. No onboard pumps or fluid circuits are required to inflate the pigging element.
