Anti-Corrosion Services

Epoxy Fire Protection: Epoxy intumescent coatings are intended for use in fire risk areas where evacuation and maintaining asset integrity is essential. Intumescent coatings provide a durable coating able to withstand corrosion when used in a system.

Fusion Bonded Epoxy (FBE): Fusion bonded epoxy is a long term solution for anti-corrosion protection and provides quick cure and turnaround on coated items. FBE can be single layer or dual layer where an additional mechanical protection is required. The steel is heated to around 200-240^oC and powder is transferred via electro-static guns or fluidised bed.

3LPE /3LPP – Buried Pipeline: 3 Layer Polyethylene (3LPE) & 3 Layer Polypropylene (3LPP) have become the industry standard for pipe coating. A first layer of fusion bonded epoxy is followed with a second layer of co-polymer adhesive with a final application of either polyethylene or polypropylene. Polyethylene is used for lower temperatures and polypropylene chosen for higher temperatures.

3-Layer Polypropylene (3LPP) is a multilayer coating composed of three functional components; a high performance Fusion Bonded Epoxy (FBE) primer, followed by a copolymer adhesive, and an outer layer of polypropylene which provides one of the toughest, most durable pipe coating solutions available. 3LPP systems provide excellent pipeline protection for small and large diameter pipelines at up to high operating temperatures.

Polypropylene is a perfect material, displaying high mechanical and thermal resistance.

Polypropylene hardness reaches 64 points in the Shore “D” scale, which is more than polyethylene. Moreover, polypropylene yielded higher results in the case of destructive tests carried out in low temperatures (in comparison to polyethylene), e.g. resistance to the environmental stress corrosion – ESCR (>3000 h for polypropylene and > 1000 h for polyethylene).

Polypropylene is resistant to UV radiation (contains UV stabilisers) and displays high thermal resistance as it is intended to be used in high temperatures (polyethylene in max. 60° C and 80°, whereas polypropylene operation temperature reaches 100°C and 110°C).

3LPP coating protects steel pipes efficiently against mechanical damage.
