Navigating the Mine-Field of External SCC Management

The passage of time inevitably takes its toll on the integrity of assets. Corrosion, in all its forms, is one of the most significant time-dependent pipeline degradation mechanisms, compromising the integrity of our pipelines and potentially reducing their remaining service life. The challenge for us, as pipeline engineers, is clear: to safely manage our pipeline infrastructure into the future.

Knowledge is Power When Protecting Pipelines from Alternating Current

Pipeline operators have realized tremendous cost efficiencies by collocating in the same corridors as high-voltage alternating current (HVAC) lines, but evolving and difficult challenges exist within these applications to protect against pipeline corrosion and safety hazards.

Mitigating Corrosion Under Insulation with Improved Water Repellency

Stone wool insulation possesses unique physical properties that make it ideally suited to a number of industrial applications including petrochemical processing. The open cell structure of stone wool encapsulates and restricts air movement, which gives it excellent insulation capabilities, while still allowing for water vapor to freely pass through.

Modeling Corrosion and Corrosion Protection

Almost every man-made structure involves the use of metals; often, non noble metals that are susceptible to corrosion. The estimated worldwide costs for corrosion derived damages are about 2.5 trillion dollars. Proper corrosion protection could save 15–55% of the cost of these damages.

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.

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.
