Internal Corrosion Protection Strategies for Aboveground Storage Tanks

In a CORROSION 2019 conference paper, the authors analyzed two case studies of corrosion-prone tanks using dissimilar metals and the challenges that arose in providing them with adequate cathodic protection (CP).

Corrosion Basics: Engineering Materials

Although the primary focus of a corrosion engineer is on the chemical stability and corrosion resistance of these materials, it is critical to cooperate with other design team members familiar with the mechanical, physical, and other properties to ensure that the desired materials performance can be achieved.

Final Report Issued on Fatal New Zealand Cruise Ship Blast

New Zealand’s Transport Accident Investigation Commission published its final report on a fatal accident involving the massive Emerald Princess cruise vessel, in which a nitrogen cylinder burst and fatally injured a nearby crew member.

New Metal Alloy Materials Slow Corrosion in Process Vessels

In this case study at a U.S. oil and gas facility, a new high-velocity thermal spray cladding solution helped stop corrosion where an older nickel-copper thermal spray coating and organic patch repairs had worn away.

Haiti Pier Preserved with New Coatings, Dust-Free Prep

In this case study, the contractor was asked to install a new deck coating system to mitigate any potential corrosion and protect against the impact of heavy foot traffic during the peak summer travel season.

Corrosion Management for Pipeline Integrity: Part 2

In the final part of this series, three experts in oil and gas pipeline corrosion management explain the value of corrosion management systems, how they work, and what programs and platforms are available to help organizations improve their performance.

New Accident-Tolerant Fuel Cladding for Nuclear Environments

A multi-year research project involving Oak Ridge National Laboratory has led to the production of an accident-tolerant fuel cladding utilizing iron-chromium-aluminum alloys.Since the disaster at Japan’s Fukushima Daiichi Nuclear Power Plant in March 2011, scientists and engineers have searched for solutions to help prevent future accidents of that magnitude.

Corrosion Basics: Effects of Coating on Corrosion and Cathodic Protection

The application of a coating can greatly reduce the amount of current required to obtain cathodic protection. In addition, good coating can significantly improve attenuation characteristics along a pipeline.

Corrosion Management for Pipeline Integrity Roundtable: Part 1

With a properly implemented corrosion management program, corrosion decisions and practices can be integrated within an organizational management system for oil and gas pipelines.

Survey Instrument Offers Enhanced Data on Pipe Conditions

The new surveying instrument measures and records both close interval potential survey (CIPS) and direct current voltage gradient (DCVG) data, along with corresponding GPS coordinates from the field.

New Method for Repairing Damaged Concrete Bridge Girders

Researchers with the Minnesota Department of Transportation and the University of Minnesota have successfully tested a new, cost-effective method for repairing damaged bridge girders that they believe can restore them to their original shear strength or even make them stronger.

Self-Healing Additives Boost Protective Coatings

The new additive system is comprised of a liquid healing agent encapsulated by a polymeric shell, which upon incorporation into a coating formulation can impart self-healing functionality to the coating. The formulation consists of an epoxy resin, a polar diluent, a corrosion inhibitor, and an adhesion promoter.

Chemistry to Tame the Power of Steam

As steam is produced in a boiler, the impurities left in the feedwater concentrate and precipitate out of the solution and onto the internal surfaces of the boiler, causing fouling. This reduces both the water flow and the heat transfer, decreasing the efficiency and power of the boiler. Such fouling can accelerate corrosion of the boiler, decreasing its life.

Study: Microbial Corrosion Led to California Gas Leak

An investigative report into the 2015 blowout of a natural gas well near Los Angeles, California, USA, cited corroded pipe casings, safety failures by a utility, and inadequate regulations as incident causes.

Nickel-Rich Coating for Saline-Alkali Soil Grounding

To improve the corrosion resistance of the grounding grids in saline-alkali soil, the authors fabricated a conductive and anticorrosive coating. After a series of tests, results indicated that an increase of nickel powder in the coating can lead to its electrical conductivity enhancement.
