Abstract

1444496 Pipe-line pig OIL STATES RUBBER CO 30 Sept 1974 42327/74 Heading F2N A fluid-propelled pig for cleaning pipe-lines comprises a cylindrical sleeve member connected via radially extending disc-like members to an axial core; the annular cavities so formed are filled with a foamed elastomer, e.g. polyurethane. In the embodiment shown, the sleeve member 10 is flexible and either pervious or contains holes to render it such; it has a length/ diameter ratio greater than 1À5 to prevent cocking and the diameter is at least 4 times that of the core 12, which, together with disc-like members 14, 16, 18 is also flexible, preferably formed of a castable polyurethane. In the fluid the pig provides a downstream spray via duct 22 which extends from the upstream end of the pig to connect with outwardly extending ducts 24. An additional bore is provided to accommodate a towing ring. In an alternative embodiment (not shown) the sleeve, disc and core members are formed integrally the disc-like members-being conicaloffer a more unidirectional propulsion characteristic.
