Life Extension of Pipelines with Crack Defects Using Composite Repairs

Composite repairs are being used widely to restore the integrity of pipelines impaired by wall thinning arising from corrosion anomalies.

Using Remote Monitoring to Evaluate Pipeline Lightning Immunity

While lightning itself does not cause corrosion, the damage it creates to a pipe’s walls, coatings and cathodic protection (CP) system can leave a pipeline vulnerable.

Corrosion Inhibitor Development for Extreme Conditions

This article discusses corrosion inhibitor development for ultra-deep-water systems that experience most of these extreme conditions, including downhole temperatures as high as 400° F (204° C) and pressures as high as 20,000 psi (1,379 bar).

Appropriate Methods for Repairing Pipelines

Over many decades now, the ever-growing network of on- and offshore pipelines has transported an increasing volume of refined petroleum products, industrial chemicals, crude oil and natural gas to commercial and household customers. North America is a case in point.

CenterPoint Completes $240 Million Pipeline Modernization Plan, Seeks Cost Recovery

CenterPoint Energy's Southern Indiana Gas and Electric utility has asked regulators for a rate increase to recover the costs of its 7-year, $240 million natural gas pipeline modernization plan.

Coating Repairs Under Way on Enbridge Line 5 pipeline

Enbridge reported it has begun repairing gaps in the protective coating on its Line 5 pipeline in Michigan's Straits of Mackinac after the damage was discovered during routine maintenance that began early this month.

NACE Partially Reopens Houston Training Center, Offers Online Courses

NACE International will begin reopening its Houston-based training center at the end of the month.

NACE-SSPC Merger Approved by Members

NACE International announced late Wednesday that its members have voted to approve the association’s proposal to combine with SSPC: The Society for Protective Coatings.

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.

E2S

E2S Warning Signals launched the flameproof STEx warning device encompasses audible, visual and combined warning devices within 316L stainless steel enclosures to protect against harsh environments where corrosion is a particular problem. The units are IECEx and ATEX approved for Zones 1 and 2 for u..

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.
