Surface Decontamination: A Clean Route to a Corrosion-Free Environment and Asset Durability

Costs associated with corrosion-induced maintenance and the replacement of public sector and industrial infrastructure is a staggering social and economic problem. Corrosion, which is not limited to region and thus a global problem, causes a heavy burden on the budgetary limitations of governments, and the profitability of businesses. Regardless of industry or application, standard approaches to corrosion remediation have proven ineffective and new long-term solutions for corrosion prevention are required.

New Metallurgy: Anti-PTASCC Solutions for High Temperature Application

PTASCC occurs by the combination of 3 factors; formation of Polythionic acid due to exposure the metal sulfide scale to oxygen and water in the aqueous phase, residual tensile stress and sensitized microstructure having the Cr carbide precipitation at the grain boundary by welding.

Data Quality Management: Mitigating Data Corrosion in the Age of Big Data Analytics

Historically, the Cathodic Protection (CP) industry has lagged behind the technology curve. It has taken years for technicians to ditch their Big Chief tablets in favor of more modern data acquisition tools. As pipeline operators have started to adopt relevant technology for gathering and storing CP data, workflow efficiency has increased. But those technologies are not always fully leveraged to improve data quality.

New Water-Repellent Coating System Reduces Maintenance Requirements Offshore

Due to the harsh marine environment and isolated location, offshore steel structures have long been difficult to maintain, leading to high maintenance costs for asset owners. In the oil & gas industry, three-coat anti-corrosive coating systems have traditionally been used for maintenance of offshore steel structures.

Measuring Crack Defects With Sub-Millimeter Accuracy

Ultrasonic crack technology, using piezoelectric transducers, is a proven and widely used solution for crack and crack-like defect detection in liquid pipelines. Over the past 20 years, only minor developments and improvements in this area were offered to pipeline operators.

Galvanic Corrosion Protection: Those Old Galvanic Potential Tables Are Finally Being Replaced

The galvanic potential tables people have been using for years often give the wrong answer. Now the U.S. Navy is taking a new approach and updating MIL-STD-889, the galvanic corrosion standard, replacing galvanic charts and tables with corrosion rate calculations. What does this mean for industry?

Corrosion Under Insulation and Insulation Material

Corrosion under insulation – CUI – has been neglected for many years, but is now recognized as one of industry’s greatest challenges with respect to materials. CUI has been the cause of several accidents involving the loss of human life and personal injury, fire and pollution.

NACE Offers Solutions for Maritime Challenges

The maritime industry is unique in that it has been part of the journey from Revolution to Revolution since long before the First Industrial Revolution ever even started; since before mariners proved the world was not flat.

Corrosion Under Insulation in the Thermal Power Generation Industry

With the rise of renewable power, some fossil-fuelled power plants are increasingly run intermittently, as much needed capacity for when renewable energy is not enough. This repeated intermittent use leads to heating and cooling of equipment, which means the plants more often pass through the 60-150°C (175°F) temperature range, the danger area for corrosion under insulation.

New Design/Material Solution for Isolating Pipelines with Chemical and Permeation Issues

Glass reinforced epoxy (GRE) gaskets were a significant improvement over prior isolation technologies, such as phenolic gaskets, which were in use since the early 1900’s. GRE has now been used to isolate pipelines in a broad range of industries for close to 50 years.

New Metallurgy: Anti-PTASCC Solutions For All Petroleum Refineries

It is known that the conventional stainless steels such as Type 316L, Type 317L, Type 321(H) and Type 347(H) have higher risk to occur PTASCC (PolyThionic Acid Stress Corrosion Cracking) in Hydrotreating units, Hydrocracking units and Delayed Coker units etc of petroleum refineries. PTASCC occurs by the combination of 3 factors; formation of Polythionic acid due to exposure the metal sulfide scale to oxygen and water in the aqueous phase, residual tensile stress and sensitized microstructure having the Cr carbide precipitation at the grain boundary by welding.

Next Generation of Epoxy Cured Cements Outperform Older Technologies

This study conducted by Florida Atlantic University was carefully designed to test the resistance of three types of cementitious products to the acidity associated with highly corrosive wastewater environments. The relative chemical resistance of calcium aluminates was compared to new generation epoxy modified mortar. Tests were conducted in the same acidic environments that would be present in wastewater infrastructure. The results indicated significant differences between the epoxy modified mortar and the calcium aluminates when comparing weight loss and pH levels. The outcome demonstrated that the epoxy modified mortar substantially outperformed the aluminates, pure fused or other.
