A unique wrap was used to repair a seawater bulk media filter vessel on an offshore oil and gas platform in the Gulf of Mexico. The bottom of the vessel was suffering from external damage due to the heavily corrosive environment and seawater being transported.
A common coating scenario is that a contractor blasts all day long, then experiences delays before coating the blasted surface. A dehumidification system can help with meeting specifications for application and achieving customer satisfaction.
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.
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.
