3-Layer Polyethylene is a multilayer coating that is as commercially recognized by its shortened name - 3LPE. As the name suggests, this coating constitutes of three functional components:
Layer 1: A high performance FBE primer or Fusion Bonded Epoxy primer. Usually the corrosion protective layer. This layer is of combination bonded epoxy which offers exceptionally good corrosion protection. The fusion reinforced epoxy contains a very great holding with the blasted steel surface.
Layer 2: A copolymer adhesive and the final constituent is an outer layer of polyethylene.This layer is the copolymer adhesive. The copolymer adhesive could be a maleic anhydride united polyethylene compound. This material has great chemical holding to the fusion reinforced epoxy and the beat layer polyethylene
Layer 3: The final outermost layer of the finish is what provides the 3LPE Coated EFW Pipe with a tougher and more durable form of protection.This layer is for physical protection and comprises polyethylene. Since the copolymer adhesive and polyethylene are comparable, they bond well with each other
3LPE coated pipes features
3LPE Coating prevents steel pipe from corrosion.
Excellent chemical resistance properties and resistance to cathodic disbondment.
3LPE Coating has got good resistance to moisture permeability.
Mechanical protection :
Top coat of polyethylene prevents abrasion and damage to fusion bonded epoxy during handling.
Polyethylene topcoat permits use of local material without relying on specific backfilling material.
High bond strength :
The external and internal 3LPE coating and lining is bonded firmly to the mild steel pipe surface and the mean adhesion strength is 125 kg/cm² (ASTM D 4541).
Long working life :
Pipe has constant performance characteristics through out the life span. Service life of more than 75 years.
Customized solutions :
3LPE external coating can be applied from diameters 25 mm to 3000 mm with lengths of up to 12m.
