ABSTRACT:
An apparatus for inserting pigs for the cleaning, purging and dewatering of hydrocarbon conveying pipelines and the like and more particularly to an improved pig launcher or loader for loading a pig into a variety of configuration pipelines. The present invention teaches a portable device configured to affix to various configuration pipes via a unique configured flange coupling system, which adapts to the flange connections for various diameter pipes. The present invention also utilizes a compressed air system for loading the pig into the pipeline, and an automatic system for venting the charged pig loader once the pig has passed from the loader into the pipeline. The present invention teaches a device configured for the loading of several pigs simultaneously, and is not limited to the loading of a single pig at a time. Further, the present apparatus loads the pig(s) well into the pipeline, allowing for less problems during the cutting and welding process. Still further, the present invention is configured to affix to a cut end of the pipeline if necessary, and will insert the pig into the pipe in vertical and horizontal positions. The present invention provides an inexpensive, portable, effective system for the launching or loading of pigs and like cleaning devices from pipelines four inches in diameter on up. Its portability allows its use in areas heretofore unavailable or too costly for a permanent pig loading, greatly decreasing the cost of the operation.
