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
SUBSTRATE
Duplex Stainless Steel
CHALLENGE
Abrasion protection on leading edges using composites and insitu touch up after re-assembly
SOLUTION
Specification and application of RB 300, a high temperature and chemically resistant coating system to get the longest life out of the new plant
SCOPE
Abrasive blast to AS 1627.4, class SA 2.5 with a nominal 60µm profile.
application of RB 300 in 2 coats with a nominal thickness of 1,000µm.
Application of 1 layers of 250g/m² multi directional mat CSM
Post cure to 60°C for 4 hours as required to manufacturers specifications
PRODUCTS
Chem-tect™ RB 300 Series – Vinyl ester Glassflake coating – providing excellent resistance against corrosion and abrasion, high temperatures and severe chemical environments
OUTCOME
Quick turn-around allowing minimal disruption to meet project milestone targets.
Strict QA requirements including DFT and holiday testing to the required voltage to ensure many years of high performance
This application will provide at least 10 years of corrosion free service with minimal maintenance
