New probe technology developed from recent academic research can conduct safety-critical testing inside galvanizing kettles holding molten zinc at 450 °C.
The measurement and interpretation of cathodic protection (CP) data in plants or other complex facilities present inherent challenges where mixed metals are electrically continuous within the protected structures’ CP system.
A second generation of a polyaspartic urethane two-coat coating system with improved wet adhesion and corrosion resistance was developed in recent years for application in warm climates with high humidity.
A novel approach is presented regarding corrosion assessment and cathodic prevention of foundations for electric transmission towers in the Persian Gulf region.
Initial test results have shown higher corrosion resistance, increased mechanical strength, and better abrasion resistance when using epoxy resin-based coatings formulated with graphene.
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.
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.
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.
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.
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.
NACE International recently published five new joint companion wet abrasive blast (WAB) standards with the SSPC: The Society for Protective Coatings. These standards define the processes for preparing a carbon steel surface to a specified degree of surface cleanliness using a WAB cleaning method.
Scientists have developed a non-chrome primer system by incorporating carbon nanotubes (CNTs) modified with organic corrosion inhibitors into an epoxy-based resin. The goal of the coating development effort was to identify promising CNT-containing non-chrome primer formulations that perform comparably to traditional chromated ones.
Some of the most critical uses of protective coatings involve service conditions that require the use of coatings as linings. They may be the same coatings that are used in atmospheric or underground service, but they are usually specially formulated for three specific purposes.
When a 200-ft (61-m) stretch of an arch tunnel on a stormwater collection line in the old town section of Guangzhou, China suffered severe damage to the brick-and-masonry structure due to root intrusion and corrosion, a spray-applied lining was used for rehabilitation.
A single-pack epoxy coating with epoxy-amine reactive functionality was recently developed that delivers reasonable shelf life and a high level of corrosion resistance that is comparable to two-component epoxy polyamide coatings.
