Petrochemical & oil-gas plants
Corrosion. Chemicals. Heat.
Protected by the right layers.
We choose the system for the chemicals, temperature and service conditions, then build it up in the right order, from substrate to top coat. When PASSAWARN installs, the manufacturer’s warranty applies.

Tank lining
We choose the system for what you store and at what temperature, then build it up on steel prepared by blasting.
A thicker laminate than epoxy, for tanks and pits where chemical resistance comes first.
- Surfacing veilA thin fibre tissue laid into the surface of the laminate to reinforce it.
- Vinyl ester laminateA thick resin layer for severe chemical service, checked against the resin chart for the chemical and temperature.
- PrimerSoaks into the substrate and bonds the layers above.
- Blast-cleaned steel (Sa 2½)Rust and mill scale blasted off, leaving a rough profile the coating can grip.Substrate
Layer thicknesses are exaggerated for clarity. Built up from the bottom.
When we install,
the manufacturer’s warranty applies.
Not just a contractor’s promise, but a promise from the technology owner. We deliver whatever brand the spec calls for.
