Initial test results have shown higher corrosion resistance, increased mechanical strength, and better abrasion resistance when using epoxy resin-based coatings formulated with graphene.
Alaska is home to many distinct environments, with each presenting its own challenges when designing for corrosion control.
Iridium is a hard, brittle member of the so-called platinum group of metals in the periodic table. As an alloying element, it increases the corrosion resistance of titanium and palladium. We know that corrosion is a reaction between a material and its environment, so why not have a look at the most corrosion resistant metal in the periodic table.
New instrumentation technology in the pipeline survey industry has helped produce and deliver results for the pipeline surveyor, analyst, and operator.
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.
The primary cause of deterioration of reinforced concrete structures is corrosion of the steel reinforcing bars due to chlorides.
Recent field experiments demonstrated that a cathodically protected perforated monopile structure could create an environment with more favorable corrosion mitigation, air quality, and water chemistry compared to a sealed structure. A newly designed perforated offshore monopile system could help mitigate corrosion within the often flooded interiors of offshore wind turbine support structures.
A new method has been developed to allow for cathodic protection of the upper/new tank bottom in a double bottom tank.
For equipment where coatings are the primary method of corrosion prevention, cathodic protection (CP) can provide a secondary method of protection to areas with coating damage or poor coverage.
The pocket-sized cathodic protection (CP) interrupter records continuous waveforms during close interval surveys and provides accurate and defensible data. The technology includes both high-speed waveform datalogging and automated waveform analysis.
This article documents projects where properly designed and installed galvanic cathodic protection (CP) systems have remained active and have met internationally recognized CP criteria for up to 20 years.
A robotic spray-applied system utilizing rigid urethane foam could become an efficient solution to fill decommissioned energy pipelines, which would otherwise require cathodic protection (CP) or the application of a more burdensome filler, such as grout, to prevent soil corrosion.
The City of San Francisco needed to determine the condition of offshore pipelines and their support structures and whether they were fit to continue operating, needed repairs or replacements, or required coating or lining repair.
This article discusses testing, analysis, and root cause identification of a leak occurred on an isolating joint installed on an oil transfer pipeline only seven months into operation.
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.
