Coating
Coating systems that protect steel in aggressive environments — above and below ground.
Coating
Anti-corrosion coatings and pipe reinforcement
The challenge
Offshore structures, petrochemical facilities, pulp and paper plants, bridges and power plants need coating systems that survive aggressive environments.
Our approach
Alternative, emission-free coating products that make production and corrosion engineering more sustainable — for assets above and below ground.
Questions
Frequently asked.
How does a coating protect steel against corrosion?
Coatings work in three ways: as a barrier that keeps water, oxygen and salts away from the steel; with inhibiting pigments that slow the corrosion reaction; or galvanically, as zinc-rich primers do by corroding sacrificially instead of the steel. Most protective systems combine these in a primer, intermediate and topcoat.
What is ISO 12944?
ISO 12944 is the international standard for protecting steel structures with paint systems. It defines corrosivity categories from C1 (very low) to CX (extreme) plus immersion categories Im1–Im4, and durability ranges from low (up to 7 years) to very high (more than 25 years) to help specify the right system.
What is composite pipe reinforcement?
Composite reinforcement restores the strength of corroded or damaged pipework by wrapping it with carbon, glass or aramid fibre laminates bonded with epoxy resin. It avoids cutting out sections and hot work. Design and installation are covered by ISO 24817 and ASME PCC-2.
