Bruce: what a wonderful technology. Pigs that clean! I love it...
I will try to implement similar things with my pigs. Maybe for cleaning oil pipelines. I have pigs with different sizes, and they should work for different pipelines. Maybe they can even be used for the oild spill in the gulf.
From Wikipedia, for clarification:
Pigging in the maintenance of pipelines refers to the practice of using pipeline inspection gauges or 'pigs' to perform various operations on a pipeline without stopping the flow of the product in the pipeline. These operations include but are not limited to cleaning and inspection of the pipeline. This is accomplished by inserting the pig into a 'pig launcher' - a funnel shaped Y section in the pipeline. The launcher is then closed and the pressure of the product in the pipeline is used to push it along down the pipe until it reaches the receiving trap - the 'pig catcher'.
So I need to think through the technology options for pig launchers and pig catchers.
