Chart recorders, deadweight testers and analog pressure gauges have been stock tools of the gas pipeline trade for decades. Each device brought several advantages technicians needed, so all three became common, despite the drawbacks they came with. Now reference recorders are available to replace all three with a single instrument.

El Paso and Spectra announced that their jointly developed project, Marcellus Ethane Pipeline System (MEPS), is holding a 30-day open season.

Koch Pipeline Company, L.P. received final shareholder approval to build a 20-inch crude oil pipeline between Pettus and Corpus Christi, TX to move Eagle Ford production.

To date, limited testing has been done to determine the effects pulsation in the gas stream may have on the ultrasonic meter’s accuracy and performance. Some previous testing does show that there may be an impact on accuracy when the frequency of the pulsation is the same as -- or a multiple of -- the sampling frequency of the ultrasonic meter.

Lone Star NGL LLC, a Energy Transfer Partners, L.P. and Regency Energy Partners LP joint venture, will construct a 530-mile NGL pipeline from Winkler County in west Texas to the Jackson County processing plant in Jackson County, TX.

As a nation as well as an industry we should be grateful for the apparent wealth of natural gas we are finding throughout the United States. It means a reliable, relatively inexpensive energy source for years to come in addition to badly needed jobs, tax revenues for governmental entities, and increased energy independence.

Southern Union Company announced July 18 that its Trunkline Gas Company subsidiary has completed the initial phase of construction to isolate its South Texas system to provide bi-directional flow for liquids-rich gas service.

Gas chromatographs (GCs) are installed all over natural gas pipeline networks, providing an analysis of the flowing gas and calculating the physical properties used for the flow calculations and for custody transfer. However, a clear understanding of just how the GC works and the considerations that need to be made for the installation and operation of the GC are often lacking in the industry. This article discusses the major components of the GC and provides an understanding of the theory and practice of gas chromatography in the pipeline industry.

Inspection and assessment capabilities in the pipeline industry are constantly improving, thanks to competitive technology developments. More advanced inline inspection (ILI) tools yield better data on pipeline condition, which in turn drives the need for advanced assessment capabilities to leverage the improved data quality and accuracy. Damage mechanisms like dents, cracks and internal and external corrosion can now be accurately quantified.
