Substrate

Chemical Storage Tank – Mild Steel, with external Cladding

Products

Epo-Chem™ RS 500P, a surface and moisture tolerant epoxy MIO primer

Epo-Chem™ RA 500M moisture tolerant glass flake filled epoxy topcoat, designed for immersed applications

Environment

Sulphonic Acid Storage at 50° C

Challenge

Existing epoxy lining on this chemical storage tank was in poor condition, with large sections experiencing deterioration alongside staining and corrosion of the tank wall. This stained the finish product preventing use until a long term solution was found.

Chemcote’s Solution

Set up scaffolding inside tank and utilised efficient surface preparation techniques to minimise mobilisation of blasting costs whilst still achieving an optimal surface to produce long term coating adhesion

Scope

Mobilise to site and set up extraction
Abrasive blast to AS 1627.4 2005 Class 2.5, 60μm profile
Application of 1 coat of Epo-Chem RS 500P to a nominal thickness of 100μm
Application of 1 coat of Epo-Chem RA 500M to a nominal DFT of 350μm
Sand flanges and finish off internals
Carry out internal QA, DFT check

Results

By coating with the Epo-Chem™ system Chemcote restored the chemical storage tank back to service, with long term peace of mind offered to the customer
