Ever since Union Gas in Caney, KS successfully inserted a 4-inch polyethylene pipeline into a corroded 6-inch steel pipeline in 1959, polyethylene pipes have steadily become the material of choice for the North American gas distribution market.
The flow measurement performance of two commercially available ultrasonic flow meters has been evaluated under conditions in which there were various levels of contaminate-like coating applied to the inside wall of the pipe upstream of the meter.
This article looks at third-generation enhancements to electro-magnetic acoustic transducer (EMAT) inline inspection technology for dry gas pipelines. The enhancements have been derived from five years of operational experience by GE Oil & Gas-PII.
The Southern Gas Association (SGA) holds an annual conference at which many subjects are discussed involving gas transmission and distribution operations.
Tony Keane, executive director of NACE International, recently assembled a panel of NACE member pipeline corrosion control experts to answer a series of questions on the challenges involved with assessing and protecting pipelines at cased road and railway crossings.
This article shares experiences we have gained working with several customers to geo-code leak and pipe inspection reports and associate them with the pipe segment in the GIS that best matches the address location and other attributes of the report.
As traditional natural gas reservoirs are depleted, producers are forced to target lower pressure wells that typically produce a “wet gas.”
Polyethylene (PE) is the primary material used for gas pipe applications. Because of its flexibility, ease of joining and long-term durability, along with lower installed cost and lack of corrosion, gas companies want to install PE pipe instead of steel pipe in larger diameters and higher pressures. As a result, rapid crack propagation (RCP) is becoming a more important property of PE materials.
Access to natural gas will be a vital part of the world’s energy strategy in the years to come. Because the regions of greatest new supplies are distant from sources, demand for liquefied natural gas is forecast to more than double by 2020.
