OVERVIEW: The project consisted of a long wall approximately 20 mt long and 2 side walls approximately 4 metres long each. This was an excellent opportunity for Chemcote to provide ultimate surface preparation and application.
Most linings were breaking down and failing within a short period of time, between 2 & 8 weeks of service.
INDUSTRY
ENVIRONMENT
1,000°C Coking Coal transport wagon where 80°C recirculated water is used to quench the load.
SUBSTRATE
Steel outlet and inlet spools, flange faces, shut off valves, turbine casing components and manway covers
CHALLENGE
After successful spot repairs on existing hot car structures insitu, we were asked to provide the same solution on a brand new fabrication. The challenge was the length and weight of the items and the attention to detail required around all the crevices and welds.
SOLUTION
We recommended Epo-chem™ RE 500P a high temperature resistant surface tolerant, Novolac Epoxy primer. Top coated with Epo-chem™ RW500, glassflake filled, high temperature resistant Novolac Epoxy. The coating system provides excellent corrosion/erosion resistance against this environment.
OUTCOME
An inspection of our spot repairs after 12 months have indicated that our glass flake coating system can withstand these harsh environments. We expect the freshly coated components to provide the most superior coating system used on this structure to date. This saves the client a lot of money and reduces a lot of equipment down time.
