Abstract
A piggable pipeline system is disclosed. One or more pig launcher/receivers may be coupled to a pipeline. At least one fitting may be coupled to the pipeline. The fitting may include a body and at least two passages through the body. The passages are in fluid communication within the body. A diverter is located in at least one of the passages. The diverter is movable between an open position and a closed position. In the open position, the diverter allows open flow between two of the passages. In the closed position, the diverter inhibits flow between the two passages. The pipeline may allow a pig to be launched from at least one of the pig launcher/receivers and returned through the pipeline to at least one of the pig launcher/receivers.
