OVERVIEW: This 304 Stainless Steel Seawater/treatment water pool filtration system required provision of long term corrosion protection with a quick turnaround
INDUSTRY
ENVIRONMENT
Seawater/chlorinated – treatment water
SUBSTRATE
304 Stainless Steel
CHALLENGE
Short time frame requiring quick turnaround. Customer required provision of long term corrosion protection.
SOLUTION
Working around the clock and the application of proven RB 300 series, a glass flake filled vinyl ester with excellent resistance to chemical and abrasive protection.
SCOPE
Grind welds and sharp edges. Machine rebate to all flange faces to prevent crevice corrosion caused by misaligned gaskets.
Abrasive blast to Class 3 AS 1627.4 75micron profile (nominal) Apply of 2 coats of RB 300 Series to a DFT (dry film thickness) of 1200 microns.
Carry out QA including holiday test @ 8kV and confirm thickness.
Externals protected with 1 coat of RL 500PF
