Breakthrough In Inhibitor Science Fights Internal Corrosion

June 2012 Vol. 239 No. 6

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.

Pig Trap Design And Assessment Considerations

January 2011 Vol. 238 No. 1

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.

Polyurethane And Pipeline Pigs Make A Perfect Match

August 2010 Vol. 237 No. 8

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.
