SECTORS C5 – CX
Petrochemicals
From structural steel to piping, from storage tanks to process equipment, we have a solution for everything. In this sector, choosing the wrong system creates not just cost but operational risk.
TYPICAL LOAD · Chemical vapour, high temperature, CUI risk
RISK ANALYSIS
This is where corrosion comes from.
- Chemical vapour and acidic condensation
- Risk of corrosion under insulation (CUI)
- Temperature cycling and thermal expansion
- Limited access due to continuous processes
RECOMMENDED SYSTEM
Coating build-up.
The layer build-up typically used in this sector. Values are indicative; the final system is determined by the site inspection report and the product technical data sheet.
PrimerZinc-rich epoxy
80 µm
Intermediate - MidcoatEpoxy High Solids
200 µm
Finish / TopcoatPolyurethane
80 µm
TOTAL DFT360 µm

Reactor and column exteriors
Structural steel and platforms
Pump and valve groups
POINTS TO NOTE
- A CUI-suitable system is essential on surfaces under insulation
- Observe application temperature limits on hot surfaces
- The chemical exposure list should be shared with the technical team
