FBE Fusion Bonded Epoxy Coating and Lining
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.
Decho 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 are AWWA C213, and API RP 5L7.
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.
API RP 5L7 Recommended Practices for Unprimed Internal Fusion Bonded Epoxy Coating of Line Pipe
This Recommended Practice provides for UNPRIMED INTERNAL FUSION BONDED EPOXY COATING OF LINE PIPE for use in transportation pipelines in the petroleum industry. Especially for the FBE Coated Line Pipes that transport via Railroad.
Before applying the FBE and Liquid-Epoxy coatings, the pipe surface shall be sandblasting cleaned to Sa 2 1/2 (Near White).
These standards are suitable for the Steel Pipes in accordance with API Spec 5L 46th Edition, ASTM A53, etc
