FBE pipe is coated with Epoxy Coatings, it could be used for internal and exernal coating, and mostly used pipe internal coating. Specified as Fusion Bonded Epoxy pipe.
FBE coating pipe is Fusion Bonded Epoxy coating steel pipe. It could be applied for external or internal coating, with heat resin for pipe. With coated a form of dry powder at thickness 400-600 microns on to the heated surface of pipe. Once the FBE coated on the pipe surface, the FBE film provides an extremely hard surface with great adhesion to the pipe surface. The FBE layer in a even form and have good resistance to the chemical reaction.
Application:Widely used in pipeline systems for the transmission of oil, gas, water and other fluids. They have highly resistance to corrosive from chemicals, moisture, harmful environment etc.
FBE can be applied at service temperatures of up to 110 °C; the typical thickness is 350 to 450 micrometres. For increased resitance to mechanical loads, additional layers of special epoxy can be applied. This is known as dual FBE coating or abrasion-resistant overlay (ARO).
FBE DUAL LAYER: 1st layer – Corrosion protection epoxy powder spray-applied with electrostatic guns in typical thickness of 250 – 275 μm.
FBE DUAL LAYER: 2nd layer – Mechanical protection epoxy powder spray-applied with electrostatic guns in typical thickness of 375 – 625 μm.
FBE MONO LAYER: Epoxy powder spray-applied with electrostatic guns in typical thickness of 350 – 450 μm.
