Description

Fusion Bonded Epoxy (FBE) Coated Line Pipe


Fusion Bonded Epoxy (FBE) coating protects pipe surfaces against corrosion. Double or triple layers of FBE may even increase the resistance to friction and abrasion. FBE coating is also used as the primer layer in 3-layer PE/PP coating systems.

Electrostatic epoxy powder is sprayed onto a pipe at a temperature typically around 220 – 235°C. On reaching the hot pipe surface, the epoxy powder melts and forms a uniform layer of epoxy coating on the pipe.


An internal FBE coating is used to protect the inner surfaces of steel pipes from the influence of corrosion and light mechanical impacts and it provides excellent resistance to cathodic disbondment.

The internal Fusion Bonded Epoxy (FBE) system is based on an epoxy powder spray system, mounted on a lance. The lance moves through the pipe while the epoxy powder is sprayed onto the internal pipe surface. The pipe must be heated so that the epoxy powder melts onto the pipe. After FBE application, the layer requires curing.


FBE can be applied at service temperatures of up to 110 degrees Celsius; the typical thickness is 350 to 450 micrometers. A second layer creates an excellent resistance to damage for the pipeline itself, even under the most difficult environmental conditions.

HSH can produce FBE Fusion Bonded Epoxy Coating and Lining with the Diameter from NPS 4″ to NPS 56″ (114.3mm – 1422.4mm)


The codes and Standards for FBE Coatings:


AWWA C213 Standard for Fusion Bonded Epoxy Coating for the Interior and Exterior of Steel Water Pipelines

These standards describe the material and application for shop and field-applied, liquid-epoxy interior linings and exterior coatings and linings used in the water-supply industry for steel water pipelines installed underground or underwater, under normal construction conditions.
