Yes, you read that correctly. It may sound like a childhood prank, but in reality pig launching is an everyday occurrence! Every one of us is dependent on the oil and gas industry, and the pipelines that carry oil and gas products to consumers. Just like the pipes in your home, oil and gas pipelines can build up residue that impedes the flow in the pipe. To keep the pipelines flowing, a device called a Pig is placed into the pipes, and travels with the flow to loosen debris and enhance throughput.
