Polyurethane And Pipeline Pigs Make A Perfect Match

  
Pigs have been squealing in pipelines for decades. A lot has changed, however, since the first modern-day pipeline pigs were introduced in the early 1940s. Many would cite the development in recent years of smart pigs, also called inline inspection (ILI) tools, as the biggest change. These pigs, which use sensors and computers to accurately inspect and analyze pipeline conditions and problems, do represent a vital improvement in the technology.
