OVERVIEW: Urgent project deadlines required a fast turnaround of repairs to a chemical plant agitator.
Chemcote was able to provide a solution that met strict QA requirements, including DFT and holiday testing to the required voltage.
Our multi-coat application of high temperature and chemically resistant coatings guarantees at least 10 years of corrosion free service, with minimal maintenance.
INDUSTRY
ENVIRONMENT
Installation of new mixing tank containing high pH contents at 60°C, with 50% solid contents and 50% iron hydroxide
