Electromagnetic Measurements Used in NDT for Pipeline Coating in Mexico
Corrosion is the chemical process through which metal tries to return to its original or mineral state. In the case of buried pipelines, the metal is exposed to corrosive processes that may eventually cause ruptures with the consequent environmental and economic damages.
Controlling Microbiologically Influenced Corrosion in Pipelines
Microbiologically influenced corrosion (MIC) refers to corrosion caused by the presence and activities of microorganisms – microalgae, bacteria, archaea, and fungi. While microorganisms do not produce unique types of corrosion, they can accelerate corrosion reactions or shift corrosion mechanisms.
Managing Selective Seam Weld Corrosion as Part of Integrity Management Plans
The industry expects that all operators take a robust approach to integrity management, resulting in safe and reliable pipelines. One of the many known threats to pipeline integrity that must be explicitly addressed is Selective Seam Weld Corrosion (SSWC). This article explores ways of reliably assessing pipelines for the threat of SSWC and actively managing SSWC when it is an active threat.
NACE International, SSPC Consider Merger
NACE International and The Society for Protective Coatings said they have continued discussions of a potential merger and will ask their members to vote on the matter within a year.

Modeling and Prediction of Black Powder Erosion of Gas Pipelines
Black powder is composed of different forms of iron sulfide (FeS), iron oxides (Fe3O4, FeOOH) and iron carbonate (FeCO3), mechanically mixed or chemically combined with any number of contaminants, such as salts, sand, liquid hydrocarbons, metal debris, and even naturally-occurring radioactive material (NORM).
Plains All American fined $3.3M for California Oil Spill
Plains All American Pipeline was fined nearly $3.35 million for a 2015 California coastal oil spill caused by the rupture of a corroded pipeline.
Parker
Parker Protecting gas turbines and compressors from dust, sand, moisture, salt and other contaminants is vital to performance and reliability. The TS1000 coalescer from Parker has been specifically developed for regions such as the Middle East and other places where this c..
Unwanted Night Moves
Whenever the subject of internal corrosion in pipelines comes up, it rekindles some unpleasant memories from my extensive time as a pipeline company spokesperson. Being part of an emergency response team for over 12 years was rewarding in many ways, but there was always an uneasy feeling when the phone would ring in the middle of the night.
Corrosion Protection Through New Cost-Effective Coating
A growing number of proactive companies are going beyond traditional techniques that have only slowed corrosion. They are turning to a new category of tough, chemically bonded phosphate ceramics (CBPCs) that can stop carbon steel corrosion, extend equipment life, and minimize the cost and production downtime required to recoat, repair, or replace equipment.
Damage Tolerance Testing of Small-Diameter Pipelines
Internal and external corrosion, as well as third-party damage such as dents and gouges, are the main causes of pipeline failures worldwide. When such damage is detected by direct inspection, or in-line inspection methods, a decision to replace, repair, or accept and monitor must be made.
Combined Flaws Represent Key Danger to Pipelines
Sergey Zubin, chief engineer of Transneft Diascan, discusses the importance of detecting “combined flaws,” or those that occur in close proximity on the pipeline, with Pipeline & Gas Journal.
Solutions to Liability Risks from Decommissioned Pipelines
One solution to protect pipeline companies from potential risks of their decommissioned pipelines comes from re-applying technology that proven in another sector entirely – the world of hard-rock mining.
Growing Role of Digitalization in Pipeline Integrity Management
Digitalization is playing a bigger role in pipeline integrity management – in particular, relating to the threat of internal corrosion.
Controlling and Stopping Flow in Polyethylene (PE) Natural Gas Pipelines
While there are several established ways to control and stop flow in PE pipes, new techniques have emerged and are worth considering. Here are some options and the advantages and disadvantages that should help you in evaluating the best method for your PE pipeline.
Strategy Shaped by Volatility
Among major supply factors, deferred maintenance continues to challenge global production. Maintenance is especially critical in basins with aging asset infrastructure, as recently evidenced by the crack in the North Sea Forties pipeline.
Pipeline Digs Get Assist From PMO
Performing direct assessments to verify a pipeline’s MAOP is not new, but as federal regulations become more stringent, the volume of digs will increase significantly, and operators need to keep up with the pace.
NACE President Looks to Bolster Corrosion Education
NACE International’s president for 2018, Jeffrey Didas, discusses corrosion education and other issues of importance to the organization in its 75th anniversary year.
More Skin in the Game: New Technology to Find, Fix Leaks
Technology has not only helped re-energize the natural gas sector of the global energy economy, but also led to safety advancements, such as methane-detection systems continuously monitor and alert operators to a significant leak.
Making Simple Smart and Smart Simple: Cost-Effective, Low-Risk Pipeline Inspection
Three brief case studies highlight the challenge, solution and outcome where innovative pigging solutions have been successfully deployed to meet major offshore operator’s requirements.
In-Line Inspection of Low-Pressure, Low-Flow Gas Pipelines
Maintaining control of an In-Line Inspection (ILI) tool’s speed is one of the most critical elements in successfully assessing the condition of a pipeline. Success is defined as receiving an intact tool at the conclusion of the inspection and acquiring data of sufficient quality to achieve the vendor’s sizing and accuracy specifications.
Accessible Pipeline Data Becomes Focal Point of Safety
Many of the world’s most vulnerable pipelines are in developed and municipal areas, where it can be difficult to locate miles of gas pipelines in these regions. And where locations exist, the data may not be in an easily retrievable and shareable format.
Polyguard Products
Polyguard Products introduced the RD-6® UVO overcoat, a single component, low VOC UV resistant, water-based liquid coating that protects Polyguard’s RD-6® anti-corrosion coating from damaging UV light rays when used for above-ground pipeline field joint girth welds, valves, fittings, and FBE coated pipe.
