FSPP – Flame Spray Polypropylene


V.I.P. Verniciatura Industriale Pesarese Srl is offering FSPP Flame Spray Polypropylene coating for pipelines.

Flame Spray Polypropylene (FSPP) technologies are particularly useful with custom pieces, bends, buckle arrestors etc., items whose shapes are difficult to coat. Powder is carried in a stream of air and is fed into the center of an annular combustion flame where it is heated.

A second outer annular nozzle feeds a stream of air, around the powder stream, which accelerates the spray particles toward the substrate and prevents burning of the powder.

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. The thicker the applied polypropylene 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.
