Coatings & Linings

Artificial Neural Network Developed to Monitor Condition of Tank Coatings

Embedded technologies can provide monitoring capabilities that capture the onset of tank coating deterioration and follow the evolution of damage.

Field Joint Coatings

Engineering and selecting the most adequate and appropriate pipeline coating depends on a multitude of factors. Careful analysis of several critical factors must be considered, such as the pipe diameter, the service pressures or operating temperatures of the transport materials, the soil conditions if installing a landline, construction techniques for installation, cathodic protection (CP), and whether impressed current CP or sacrificial CP will be used.

Corrosion on the High Seas: How Ship Owners Battle Rust

Because seawater contains a significant concentration of dissolved salts and is very corrosive to steel, infrastructure and assets in or near marine environments are particularly susceptible to corrosion.

2018 Deadline Nears for New U.S. Underground Storage Tank Rules

The third and final deadline for underground storage tank owners and operators to meet new federal requirements from the U.S. Environmental Protection Agency for spill, overfill, and corrosion protection is October 13, 2018.

PHMSA: Weight on Keystone Pipeline Led to Coating Failure, Oil Spill

The installation of a weight on the Keystone oil pipeline in South Dakota upon its construction in 2008 appears to have caused mechanical damage to the coating, leading to a recent rupture and oil spill.

Thin Carbon Coating Reduces Carbon Corrosion in Water Electrolysis

Researchers have developed an alternative, less expensive anode material for alkaline water electrolysis, which they say promotes less carbon corrosion. The researchers say their new nanostructured catalyst can reduce the rate of carbon-induced corrosion often experienced in alkaline water electrolysis, used to produce hydrogen from renewable resources.

U.S. Air Force Targets New System to Evaluate Aircraft Coatings

A new system for evaluating coating performance is expected to accelerate the screening, qualification, and implementation of new aircraft coatings.

The Science Behind It: Effects of Silane Additives on Corrosion Resistance and Durability of Mortar

Silane coupling agent additives were used in mortar in varying proportions, and the effect of the coupling agent content on the mortar’s corrosion cracking resistance and durability properties was studied.

Thermal Imaging Used for Nondestructive Testing of Concrete Pillars

Russian scientists recently used a thermal imaging technique to study the corrosion of steel reinforcement within 14 reinforced concrete pillars.

Evaluating Internal Pipe Coatings with Electrochemical Impedance Spectroscopy

A new generation of high-temperature fusion-bonded epoxy coatings are being developed as a lower-cost alternative to alloy steels for protecting the internal surface of tubing, casing, flowlines, and pipelines.

Formation of Corrosion-Resistant MAO-Treated Aluminum Alloy

Micro-arc oxidation coatings were formed on an aluminum alloy in a silicate-based electrolyte with and without the addition of aluminum oxide.

Process Vessel Linings Seen as Corrosion Solution for Iraq Oilfield

An internal lining for 40 newbuild vessels to be shipped to and installed at the Rumaila oilfield in Iraq was found to be the most efficient corrosion protection solution.

New Rotor Blade Inspection Methods for Offshore Wind Turbines

Industrial and research partners are collaborating to investigate alternative inspection methods on wind turbines through the use of acoustic emissions monitoring systems and offshore drones equipped with thermal imaging cameras.

U.S. Army Develops Sensing Network to Spot Aircraft Damage

Networked sensors open up possibilities for new onboard aircraft features that could immediately alert the flight crew to structural damage as it occurs, like matrix cracking and coating delamination.

The Science Behind It: Coating Technology for Pump Energy Savings

Premature failures of pump components can be caused by cavitation phenomena, erosion-corrosion, and other mechanisms.
