Fusion Bonded Epoxy (FBE)

Product Description

FBE coating is a thermosetting resin applied in the form of a dry powder onto the heated surface of steel pipe. The most frequently used powders are those based on epoxy resins, applied at thicknesses of 400-600 microns

The cured film is homogeneous, with optimum adhesion to the steel and good resistance to chemical reaction.
The coating application system consists of numerous electrostatic spray guns that uniformly deposit the epoxy powder onto the blast cleaned, chemically treated and preheated surface of the pipe.

The correct surface temperature allows the fusion of the powder and assures the polymerization process, which is completed with a final cooling stage. Once applied and cured, the epoxy powder achieves an extremely hard surface with excellent adhesion to the steel surface.

Tenaris FBE Options

FBE Dual

This unique Fusion Bonded Epoxy System is applied as a powder base coat and powder top coat simultaneously with the typical application system for the conventional FBE.

This coating is recommended for pipelines operating in the toughest enviroments, including river and road crossings and rocky, mountainous terrain. It has excellent impact resistance and abrasion properties which combined with its good flexibility provides good protection against possible damage to the coating during pipe transportation and pipeline construction.

FBE Non Slip

The steel is coated with a dual powder system. Firstly, a regular Fusion Bonded Epoxy resin layer provides corrosion protection, then a second layer of a modified FBE resin is applied for a rough finishing.
The main purpose of this type of coating system is to provide a rough, non-slip surface for a pipeline that will subsequently be concrete coated.

Three Layer Systems: Polythylene & Polypropylene

Product Description

Pipe is blast cleaned, preheated and one layer of Fusion Bonded Epoxy powder (FBE) is then applied. While the FBE is still in its gelled state a copolymer adhesive layer is extruded onto the FBE, followed by a layer of extruded Polyethylene or Polypropylene until the desired thickness is obtained.

Tenaris Three Layer Options

	Three layer Polyethylene Suitable for temperatures between -40ºF and 176ºF ( -40ºC and 80ºC)
	Three layer Polypropylene Suitable for temperatures up to 248ºF (120ºC)

In addition to the chemical and adhesive properties of the epoxy powder, the polyethylene 3 layer system provides physical and mechanical advantages, whilst the polyproplene system also ensures performance at high temperatures.

Advantages of Three Layer Coating

	Excellent corrosion resistance: When exposed to either acid or base media, assures extended lifetime in highly corrosive soils.
	Strong steel adhesion: 20 times more adhesive than traditional plastic tape systems.
	Excellent cathodic disbondment test results.
	Optimum impact resistance.
	Free of holidays: The hot extrusion method used to perform the coating assures a continuous and a uniform thickness profile, without air bubbles and holiday free.
	High dielectric resistance
	Superior bendability for laying
	Impermeability: Both the high density Polyethylene and the Polypropylene have low water permeation characteristics which are less than those of any other pipeline coating system.
