To investigate the feasibility of probabilistic analyses of the peak uplift resistance in frozen soils by varying parameters that are known to be important for the development of the uplift resistance under the upward movement of a pipe. A buried…
Two important and current topics of interest for gas machinery operators are emissions and energy efficiency. Current climate change legislation is leaning towards reduced emissions and improvements in energy utilization efficiency, which has renewed…
A large portion of current natural gas metering technology requires a fully-developed velocity profile for accurate flow measurement results. Two methods can be used to obtain a fully-developed velocity profile in natural gas pipelines: long lengths…
Composite materials have been used to repair high pressure transmission pipelines. Over this time period a wide variety of composite systems have been developed and evaluated. With the increased demands being placed on pipeline systems around the…
In many applications within the oil and gas industries, and in particular in the measurement of flow, differential pressure transmitters must operate with high accuracy and repeatability. The uncertainty of the measurement of flow varies…
Turbocharger performance, especially on SIP-call engines, remains essentially unmeasured even though tracking information over time would provide critical information to help field engineers lower their engine emissions as well as the cost of…
There are a number of COTS RTQM systems available today both stand-alone and integrated into welding power supplies, each with its specific advantages and disadvantages. For proper selection, the end user needs to identify and prioritize their needs.…
New regulations and modifications to existing environmental regulation are currently underway. Regulations include the ozone national ambient air quality standards and the nitrogen dioxide (NO2) one hour standards. Based on the proposed changes, a…
Approximately 100 citations and 50 U.S. patents were identified on the subject of HDD in permafrost environments, through 12 databases.The search was not limited by date or by language, in order to get a broadly based output.
In the liquids pipeline industry, large horsepower and flow pumps are used to transport liquid along the pipeline. When these pumps are purchased, they are performance tested with water. Performance tests are also sometimes conducted after a pump has…
