Introduction of FBE corrosion Steel Pipe



FBE coating steel pipe is fusion bonded epoxy coating steel pipe.It is a kind of external heat resin used for pipes.With 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 surface of pipe.The FBE layer in a even form and have good resistance to the chemical reaction.

 

Fusion bonded epoxy (FBE) coating are used to prevent corrosion and harmful chemicals of steel pipes.This is a thin coating made of epoxy-resin powder material in a thin film and applied to pipes by a special coating device for electrostatic spraying.These FBE coated pipes can be used in temperatures up to 85oC in dry conditions.



Advantages of fused epoxy powder coated steel pipe



1. Adapt to buried and humid environment, and can withstand high temperature and extremely low temperature.

2. Strong anti-interference ability. If the coated steel pipe is used as a cable sheath, it can effectively shield external signal interference.

3. Good pressure resistance, the maximum pressure can reach 6Mpa.

4. Good insulation performance, as a protective tube for wires, there will never be leakage.

5. No burrs, smooth pipe wall, suitable for passing wires or cables during construction.
