Devcon ® Titanium Putty & Devcon ® Brushable Ceramic Coatings Repair & Protect Pressure Vessel from Corrosion Case Study

PublishTime：2024-02-24

■Problem:
▲A petrochemical facility based in the Gulf region had a corroded pressure vessel that needed to be urgently repaired.With signs of cavitation evident within the equipment and increasing risk of leaks, the customer was seeking a safe,quick and economical repair solution.
▲Replacing the equipment in its entirety was not fast or cost-effective. Welding was not appropriate due to safety concerns and environmental factors. In addition, temperatures in the region could reach as high as 122°F / 50°C. Given most of the repair work needed to be manually applied inside the 108” (9 feet) carbon steel vessel to protect the equipment from corrosion and leaks, the repair work needed to be fast and easy.
■Solution:
▲High-performance Devcon Titanium Putty and Devcon Brushable Ceramic coatings were selected to repair and rapidly return the pressure vessel back to service.
●For preparing the surface of the vessel’s internal shell,the bottom half of the vessel was blasted to SA3 –SSPC5 with a surface profile of 80μ to 90μ. The surface profile check test was carried out by the customer to ensure the required specifications were met.
●Devcon Titanium Putty part A and part B were thoroughly blended on the mixing board using a 3” mixing spatula. This was used for filling and fairing the anomalies / defects in the vessel.
●Devcon Titanium Putty was then spread to fill up all the anomalies, then the application thickness was unified over all pitting locations. After curing, the first coat of Devcon Brushable Ceramic was applied using a hand brush.
●The Wet Film Thickness of Devcon Brushable Ceramic was confirmed to be within the acceptable range (350 to 500 microns). An additional coat was applied using the same methodology. No spark was shown by the Holiday detector upon completion.
