Non-Intrusive Pig Signallers: Cutting Costs, Emissions, and Environmental Risks

By their nature, non-intrusive pig signallers do not require a nozzle hole for any type of welded fitting, whether it be a 'counter flange' or a direct fitting like a threadolet. They are simply secured to the pipeline. Simultaneously, this approach saves costs on welding, non-destructive testing, and eliminates the risk associated with potential hydrocarbon leak paths.

Fatigue, Burst Tests Among Best Ways Assess Pipeline Welds

(P&GJ) — All over the world, the pipelines of large diameter and relatively thin wall thickness are used to transport hydrocarbons. These pipelines or piping systems are usually comprised of girth welded joints.

Residual Stress in Predicted Failure Pressure Calculation

(P&GJ) — Pipeline safety regulations require performing a calculation of the predicted failure pressure (PFP) of defects as part of an engineering critical assessment. Whether to include residual stress from pipe manufacturing, and selecting the magnitude of residual stress, can significantly affect the outcome of the PFP calculation. Guidance for accounting for residual stress is inconsistent.

Polish pipeline operator PERN said on Tuesday that it had restored the Druzhba oil pipeline to full functionality as expected after discovering a leak.

Poland Detects Leak in Russia's Druzhba Oil Pipeline

Polish pipeline operator PERN said it had halted pumping through a section of the Druzhba pipeline, which carries oil from Russia to Europe, after detecting a leak in central Poland on Saturday, but it expects flows can be resumed on Tuesday.

Criteria to Consider in Selecting Water Transfer Flow Meters

(P&GJ) — The oil and gas industry contains a complex number of flow applications, featuring a myriad of fluids and gases that challenge even the toughest of flow instrumentation. So, choosing the right flow meter for a water transfer application should be straightforward in comparison … right?

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.

ROSEN Conducts Research on Hydrogen Embrittlement

(P&GJ) — The ROSEN Group, together with National Gas (formerly National Grid Gas Transmission), has started researching ways to mitigate the potential for embrittlement of pipeline steel in hydrogen service.

SLB and Eni Form Partnership for New Pipeline Monitoring Technology

(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.

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.

US to Spend $700 Million for Oil and Gas Sector to Cut Methane Emissions

The U.S. government will provide up to $700 million in funding to monitor and reduce methane emissions from the oil and gas sector, setting aside half of the amount for grants to states, two agencies said on Monday.

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.

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.
