Project Description

3LPE – Triple layer polyethylene


V.I.P. Pesaro is one of the few companies able to offer the 3LPE coating on pipes as well as on custom pieces.
The coating is a multilayer composed of a primer fusion bonded epoxy (FBE) followed by an adhesive copolymer and another layer of polyethylene which provides resistance and long-lasting protection.
The system ensures the applicability of the sintered coating also on pieces with special shapes.

Long-lasting corrosion protection
The FBE primer offers an excellent adhesion to the substrate and provides a long-term corrosion protection for pipelines operating at moderate temperatures.
It also ensures the resistance to the cathodic disbondment so the total cost of cathodic protection of the pipeline decreases.

Remarkable mechanical protection
The applied polyethylene layer protects the pipeline during shipping and installation reducing repair costs and providing a protection underground against mechanical, chemical and abrasive attacks.
Applying an higher polyethylene thickness the mechanical protection increases proportionally.

Other advantages of the sintered system
V.I.P. Pesaro using this special application technique is able to coat also specific pieces with special shapes (bends, tees, reducers, joints, etc.).
There aren’t any limitations about the amount of pieces to coat, even the single piece can be treated.
3LPE can be applied in different thicknesses to meet the requirements of project specifications.

3LPE - Triple Layer Polyethylene
  • Small and large pipes
  • Standard fittings
  • Wide radius bends
  • Special fittings
  • Surface preparation: over pre-heating, blasting and testing
  • Anticorrosive coating*: oven pre-heating, FBE spray powder
  • Adhesive layer: spray adhesive, oven
  • Top coat: polyethylene (PE) spray powder, air cooling
  • Testing, packing, ready for shipment

*Sintering is the coating process where a coating powder is sprayed on a preheated piece. Thanks to the heat emitted from the surface the powder fuses creating an homogeneous and continuous layer.

Selected from among the top qualified international brands by the biggest companies.
