There are over 2 million km of oil and gas production pipelines worldwide and ensuring the effective and efficient flow of products through these pipelines makes a huge difference in revenues generated.
For pipeline owners and operators, efforts to mitigate or control internal corrosion generally fall into one or more of a handful of strategies. Moisture content control seeks to limit the amount of moisture (as measured in grains of water per million cubic feet of product, or by dew point) to eliminate the electrolyte for corrosion cells to develop.
A pig trap must be designed to match the pipeline section design specifications. The mechanical design characteristics of the pig trap should meet or exceed the design pressure, have the same design factor, have compatible material type, be designed using the same design code and be suitable for the same temperature range as the pipeline section that it serves.
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.
