This is just a starting point. There are lots of types of pigs out there from ones to clean a pipeline, to separate two different products to being able to do QA analyses on pipelines.

I agree with you 100% Mr. mgp (Mechanical), That was teh best Pipline Pipping every seen.

Some of them are the so called pipe inspection pigs.
Its function is to assess the pipe for obstructions, corrosion (i.e. wall thikness), coating quality, etc.
Modern sofisticated pigs have scratchers and sensors (typically resistivity sensors in pads), and electronic means for storing and transmitting the data.
A pig louncher is usually a dead end segment of the same pipe conected to an elbow close to one end of the pipe.
The pig is lounched and pushed by pumping fluid (which could be specific for the operation or njust the regular fluid transported in the pipe).

I hope this helps

We load multiple products into railcars over a 1000' distance using automated pigging that pigs the line to the car and then back to the blender between loads to prevent contamination. Load a recipe, click a button, and the system takes care of the rest.

The prover is a section of pipe with a "sphere" launcher and catcher at each end. The sphere is a special form of pig. It forms a positive seal between incoming and outgoing fluid.
With flow from the flowmeters diverted through the prover, a sphere is launched into the flow at the start of the prover and caught at the other end. As it passess through the prover it passes a number of sensors which precisely locate its position and time at that position. Thus the volume of fluid displaced through the prover and rate can be very precisely determined. This data is then correlated with the flow meter data to calibration check/correct the flowmeters.

In Arabic I don't believe there is a "P" sound, though there is in Farsi. Hence the "Primus" lanterns blowtorches etc were re-named "Brimus" for the Arab speaking world. This change is then reflected in the Romanised name. So this might be the reason behind the changed label.

Since then Technology has come a long way, The pigs have evolved and got smarter they now carry computers on board, so you see now we have dumb pigs and smart pigs!And dont forget the magic pigs, they actually dissappear!
