Project Description

3LPP triple layer of polypropylene

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-term anticorrosive 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 resistance to cathodic disbondment so the total cost of cathodic protection of the pipeline decreases.

Very good mechanical protection
The layer of applied polypropylene protects the pipeline during transport and installation, thus reducing repair costs and guarantees underground protection against mechanical, chemical and abrasive attacks.
The thicker the applied polyethylene the higher the obtained mechanical protection.

Other advantages of the sintered system
V.I.P. 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.
3LPP can be applied in different thicknesses to meet the requirements of the project specifications.

  • Small and large pipes
  • Standard fittings
  • Wide radius bends
  • Special fittings

Pipes:
Diameter from 1/2” to 120”
Maximum unit length 13.5 meters
Maximum unit weight 15,000 kg.

Fittings and/or special pieces:
Curves, T-shapes, reductions, flanges, etc.
Maximum size 3.0 x 3.0 x 13.5 meters
Maximum unit weight 15,000 kg.

Joints and/or custom pieces:
Bends, tees, reducers, flanges, etc.
Maximum unitary size 3,0 x 3,0 x 13,5 m

  • Preparing and testing: oven pre-heating (if required), blasting, testing
  • Anticorrosive coating / Sintering: oven pre-heating, FBE spray powder
  • Adhesive layer: spray adhesive, oven baking
  • Top coat: PP spray powder, air cooling
  • Check, storage and delivery: 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.
