Abstract: A scraper pig for cleaning tubes and pipelines comprising a flexible core provided with a casing in which scraper studs are embedded in a manner whereby they protrude sufficiently to perform a cleaning action when they are propelled through the tube. A method for the manufacture of the pig and the design of the stud is also provided.
Abstract: An intelligent pig for pipeline monitoring comprises a single body containing signal transmitters and receivers provided with replaceable rings for centering the body within the pipeline, the rings may be provided with brushes which help center the pig within the pipeline and also aid its passage through pipelines which may contain bends and/or be of variable diameter, the pig may be used in combination with a cleaning pig to provide combined activities using a common driving force.

Abstract: A method of monitoring a tube or pipeline, wherein an IP comprising an electronics module arrangement, is driven along the interior of the tube or pipeline by fluid pressure, wherein the IP transmits monitoring signals through the fluid that provides the pressure to the wall of the tube or pipeline, receives signals returned from the wall, analyzes the returned signals and stores data relating to the condition of the wall of the pipeline.
