New Approach to Digital Pipeline Integrity Management
(P&GJ) — Pigging is an operation that is regularly required by pipeline operators for both cleaning and data collection (intelligent pigging). Managing pigging schedules and risks is a significant challenge to operators/pigging vendors without an intimate knowledge of the pipeline.
Nanoparticles Transform Pipeline Cleaning, Integrity Management
(P&GJ) — Oil, gas, and multi-phase pipelines can be fouled with several types of deposits or internally restrictive debris. The actual type of fouling is dependent upon several factors including: the production fluid characteristics such as hydrocarbon product, water, and gas composition; the presence and composition of common oilfield contaminants, such as hydrogen sulfide, carbon dioxide, mercury, arsenic, zinc, lead, iron, and manganese and operating conditions (e.g., temperature, pressure, pH, flow regimes, etc.).

Safety Techniques for Aboveground Natural Gas Pipelines
There are a variety of techniques used to enhance the safety of aboveground natural gas pipelines. Coatings to minimize corrosion are an example of a safety aspect used by natural gas operators.
DIMP-Related Pipe Replacement Work Continues in Full Force US
While the amount of work to replace cast-iron and bare-steel pipe has declined in volume since the implementation of the Gas Distribution Integrity Management Program in 2009, there is still plenty of construction left to be done.
Highway Traffic and the Effect on Pipelines
Ruptures of natural gas pipelines in right-of-ways of roadways are less common, but when they occur, the devastation can be far more extensive than the more common ruptures.
Increased Safety for Natural Gas Pipelines
Local hard zones can cause sudden stress corrosion cracking in the through thickness direction. To detect and eliminate these local hard zones reliably during plate production, Dillinger developed a special eddy current testing system.
Challenges of Installing a New Pipeline
During the installation of a new pipeline, corrosion engineers must consider many different aspects of the pipeline and its corrosion protection. On the surface it may appear simple, thinking only of coatings and cathodic protection, but once construction is underway, the tasks are many.
Nigeria Losing 200,000 BPD to Pipeline Damage, Minister Says
Nigeria is losing an average of 200,000 barrels of oil per day - more than 10% of its production - to pipeline vandalism, the country's information minister said on Monday.
Key Win for Enbridge Oil Pipeline as Minnesota Court Affirms Regulator Approval
The Minnesota Court of Appeals on Monday affirmed a state regulator's decision that there is sufficient need for Enbridge Inc to replace its Line 3 pipeline, handing the Canadian company a crucial victory in its lengthy battle with environmental opponents.
