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.

3LPP coating displays extremely good performance in the following areas:

adhesion of to steel pipe surface,

resistance to impacts,

resistance to abrasion,

resistance to penetration force,

hardness and stiffness,

unit grounding resistance of the gas main.

3LPP Pipe Coating is used for construction of long distance pipelines for combustible liquids and gases, nuclear station pipelines, heating system pipelines, general-purpose pipelines, vessels, mechanical engineering and instrumental engineering.
