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.
Inorganic zinc silicate coatings, whether solvent- or water-borne, provide a number of unique challenges for the specifier and applicator. This article answers questions relating to selection, application, and maintenance of these coatings.
Corrosion impacts all structures in a marine environment, such as offshore platforms and rigs and ocean-going vessels. One way to minimize and mitigate the effect of some types of corrosion is through the use of flexible surface coatings.
The repair and maintenance industry has employed many different techniques to combat flange corrosion. A gas supplier decided to commission a flexible and peelable coating system for the protection of over 500 flanges on the site.
Average annual salaries in 2016 are reported for corrosion professionals in the United States, Canada, United Kingdom, and Europe. A slight gain was seen for the United States and United Kingdom, while a larger increase was recorded in Canada.
Advanced polyurea coatings and liners can provide strong, flexible waterproofing to bridge cracks and protect against future cracking and deterioration.
Researchers have concluded that HVOF-sprayed coatings comprised of UNS R50250, UNS N10276, UNS N06625, and UNS S31603 can provide a cost-effective corrosion mitigation method for infrastructure likely to be in contact with a mixture of wet supercritical CO2 and H2S.
To upgrade legacy medical devices under new regulations, the medical device industry is aggressively investigating and applying plasma-applied coatings to products such as stainless steel guide wires, catheters, stents, and vascular surgical tools.
This case study presents the results of evaluations and repairs made to a sulfur tank at a gas plant in central Alberta, Canada. The repairs exceeded the owner’s expectations for performance and have not required any subsequent concrete repairs of significance.
Surface preparation and coating application during the new construction of a vessel compose a complex orchestration that requires the coordination of every department in a shipyard. It is also one of the most expensive parts of building a new vessel.
Flanged pipework can be isolated from corrosive environments by using a flexible, liquid-applied elastomeric material that can be peeled off for inspection and then resealed.
In September 2015, when the iconic Rio Grande Gorge Bridge reached its 50th year of service, it coincided with the bridge’s biennial inspection that scrutinizes the entire structure for coating failure, corrosion, cracks in the steel, and other structural integrity issues.
Coating failure has led to significant degradation of America’s structural elements. As an alternative to more traditional materials, new high-performance, spray-applied waterproofing alternatives are being used to protect and maintain critical infrastructure
NACE International and the Institute of Electrical and Electronics Engineers (IEEE) have joined together to provide joint industry standards that address above-grade and below-grade corrosion of steel transmission and distribution structures.
This former combat vessel suffered from numerous leaks and a pitted surface. It needed a long-term coating repair solution capable of bonding to a poor substrate with rapid curing times.
