Mild steel substrate
1,000°C Coking Coal transport wagon where 80°C recirculated water is used to quench the load.
After successful spot repairs on existing hot car structures insitu, we were asked to provide the same solution on a brand new fabrication. 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 Chemco to provide ultimate surface preparation and application. The challenge was the length and weight of the items and the attention to detail required around all the crevices and welds.
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.
Abrasive blasting to AS 1627.4 Class 3, 60µm profile.
Most linings were breaking down and failing within a short period of time, between 2 & 8 weeks of service. 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.
