There are small pigs , big pigs , fat pigs and intelligent pigs! (TCN)

We are told the pig is one of the most intelligent of animals. But, we are not talking animals here . A pig used to be a sphere with brushes or scrapers on its periphery which was put into a pipeline and went down with the flow in order to clean the pipe - and you just hoped it would not get stuck. If it did you had a big problem finding it and the flow was stopped until you did . Things have moved on very considerabley since the 80's when I was involved with the manufacture of pig launchers and the latest pig is called an intelligent pig . It can do many things like detect leaks and measure the wall thickness of the pipe (or more importantly , the lack of it .)These things are satellite controlled and can thus pinpoint exactly any problem in the pipeline. TCN have developed what is probably the most versatile pig in the world - and that is only one of their 3 products.
