PetroChina Pipeline Research Center (PPRC) developed the PUGW-1 pipe screening system based on ultrasonic guided wave (UGW) theory during 2005-2009. PRRC is China’s largest research center focusing on oil and gas transmission and storage-related research.
Over the past 15 years, natural gas ultrasonic meters have transitioned from the engineering lab to wide commercial use as the primary device of choice to measure gas volume for fiscal accounting. Wide acceptance and use by gas pipeline companies has occurred during this time due to the device’s many strengths:
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.
