Sudden Decompression: When the Pressure Gets Released
(P&GJ) — While many integrity management techniques attempt to detect flaws in the early stages, the potential always exists for a defect to initiate a running fracture along the length of a pipe. Cracks can be initiated by, for example, excavation damage, corrosion, or ground movements and may not provide any early warning.
Strengthening the Bond with Reliable Structural Adhesives
(P&GJ) — Most industrial maintenance or repair procedures involve welding or the use of mechanical fasteners as these can be perceived as easy and quick. However, while these procedures might initially seem to correct the issue but may cause more harm than good.

(P&GJ) — The alliance covers the deployment of e-vpms technology for pipelines transporting liquid hydrocarbons and produced water and enables the detection of product loss attributable to external events such as attempted product theft or accidental impact, corrosion related leak events, and land movement events caused by earthquakes or landslides.
TC Energy's Columbia Gas Pipeline Explodes Near Virginia's Interstate 81
(P&GJ) — A gas line explosion occurred near Strasburg, Virginia, in rural western Virginia, not far from Interstate 81. The incident took place on Tuesday morning and was promptly responded to by local officials, according to The Associated Press.
Developments in Custody Transfer Metering of Natural Gas
(P&GJ) — Natural gas has become an even more important energy source as the world looks to transition away from coal-fired power plants. Natural gas emits about half of the carbon emissions as coal, so it has many countries looking to adopt it as a larger part of their energy infrastructure.
Managing Lost and Unaccounted for Gas Volumes
(P&GJ) — Lost and unaccounted for (LAUF) gas is a calculated value that compares the amount of gas coming into a system (purchased) to the amount of gas leaving that system (sold or otherwise accounted for). Although LAUF is often equated to leaking pipes and equipment, leaks generally only represent a small portion of the value.
Importance of Moisture Analysis in Pipeline Transportation
(P&GJ) — Nearly every substance is affected by moisture, which can alter physical, chemical and electrical properties. When transporting hydrocarbons such as natural gas, the presence of moisture in the pressurized stream can create serious problems.
Natural Gas Connection Failure Investigated in Fatal Pennsylvania Factory Explosion
(P&GJ) — Federal safety inspectors confirmed Tuesday that natural gas seeped through a faulty connection at a Pennsylvania chocolate factory where a strong explosion destroyed one building, severely damaged another, and killed seven people
Cheniere Energy's Sabine Pass LNG Plant Returns to Normal
Cheniere Energy Inc.'s Sabine Pass LNG export facility returned to normal processing levels on Thursday following an outage at one of its units on Tuesday, Reuters reported.
Why Flowmeter Calibration Sometimes Lacks Accuracy
(P&GJ) — The oil and gas industry appears to be favoring a move toward using “newer” and more “advanced” flow measurement technologies, such as ultrasonic and Coriolis devices as an alternative to turbine and positive displacement meters.
New Leak Detection Rules for Pipelines Proposed
(P&GJ) — The federal pipeline safety agency has proposed major changes to its leak detection, based not on concerns about safety but rather in order to reduce methane emissions based on their contribution to climate change.
Editor’s Notebook: Alaska’s Long Road Back
(P&GJ) — With the Biden administration’s recent approval of exports from a proposed LNG project and the rejection of a lawsuit challenging construction of related infrastructure, prospects may again be looking up again for the Final Frontier.
Ohio's Columbiana County Evacuates 450 After Gas Leak at Hilcorp Energy Well
