Failure of FBE Coatings in Gas Transporting Pipelines

Utilizing various analytical techniques, this article focuses on a failure investigation of both liquid epoxy and fusion-bonded epoxy coatings for internal applications in sour gas pipelines.

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.

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 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.

Salt Spray Corrosion Performances of Amorphous Al-Ti-Ni Coatings

The effects of power on the obtained coatings were investigated using a salt spray corrosion test, with results showing that porosity and cracks on the arc-sprayed coatings were significantly eliminated with the increase in power.

VCIs as Alternative Corrosion Inhibitor Technologies

The use of vapor corrosion inhibitors in coating formulations has shown that in many systems, they can replace the older technology or significantly improve the performance of the system by working in synergy with the existing inhibitors.

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.

Hybrid Nanocoating Extends Life of Industrial Coating Systems

The single component, humidity cured, polyurethane/polyurea hybrid nanocoating penetrates into the pores and voids of new or highly oxidized paint systems to form a hard, protective topcoat surface.

Thixotropic Gel Halts Subsea Corrosion of Carbon Steel

The FlexGel range of products are designed to halt the corrosion of carbon steel in subsea flexible and steel risers in the area of an outer sheath/coating damage. The innovation displaces oxygenated seawater from the region of the damage and replaces it with a noncorrosive gel.

Study Evaluates Offshore Coating Performance on Stainless Steel

The objectives of the study were to develop a protocol for testing protective coating performance on pitted SS, evaluate how various surface preparation methods affect the coating performance on pitted SS, and determine a reliable coating application procedure to cover the pits with a holiday-free film so the integrity of offshore pitted SS is improved.

Surface Inhibitors Preserve Reinforced Steel Concrete Structures

Surface-applied corrosion inhibitors, which penetrate the concrete and form a protective film on the steel rebar, have successfully reduced the rebar corrosion rate and extended the service life of many types of reinforced concrete structures.

Inorganic Coating System Halts Corrosion Under Insulation in Oil, Gas Assets

A major oil and gas operating company recently revised its engineering standards to include a novel water-borne spray coating system to protect against both atmospheric corrosion and corrosion under insulation (CUI).

Lasers Could Replace Sanding, Blasting for U.S. Air Force

U.S. Airmen with the 60th Maintenance Squadron (MXS) at Travis Air Force Base in California, USA are one of two bases currently testing a pair of lasers as a new method of removing paint and corrosion on aerospace ground equipment. They say their traditional method involves the use of an orbital sander or blasting machine.

Corrosion Management of Steel Anaerobic Digesters, Sludge Tanks

Fermentation and oxidation processes used by anaerobic digesters in biomass plants can create a perfect recipe for corrosion, both at the gas and liquid phase. Sludge tanks also face similar issues.

Exploring Differences in Epoxy and Polyurethane Floor Coatings

Experts with a coatings specialist company explain the differences between floor coating systems based on polyurethanes and epoxies, and why the selection often depends on jobsite location. With each system offering differing properties suited to specialized uses, choosing the wrong solution can lead to costly repairs or even complete floor failure down the line.
