Progressive Dewatering and Inhibitor Dispersal Rolling Pig |
摘要 |
A method for progressively dewatering a pipe or pipeline includes the use of a loose-fitting spherical- or quasi-spherical shaped pig body which rolls forward through the interior space of the pipe and temporarily captures and redistributes a portion of the volume of liquids available for capture and redistribution as the pig body rolls on past. Preferably, the portion captured is less than the volume available for capture. A part of the captured liquid may be redistributed to an upper quadrant of the pipe. Capture and redistribution are accomplished by way of a first bypass pathway and a second bypass pathway. One of the pathways may be a through-body pathway. The pig body may be a hollow pig body with a plurality of spaced-apart ports, a solid pig body with a plurality of paddle-like structures, or a cube-sphere type pig body with recessed external wall surfaces. |
