Description:
3PE anti-corrosion coating production line means the steel pipe is
protected by three layer to prolong the life of use from 5-10years
to 50-100years.
First layer is Fusion bonded epoxy layer (FBE> 100µm), the
second layer of adhesive (AD) 170 ~ 250µm, the third layer of
polyethylene (PE) 2.5 ~ 3.7mm. Present we can made the machinery
for diameter range Φ159 ~ Φ1220.
3PE steel pipe outer coating has a high mechanical strength,
excellent electrical insulation performance. The merits include
high degree of mechanization, process parameters stable, not
pollute the environment, etc. In recent years, the intensive of the
pipeline corrosion engineering has been widely used.
3pe have Long-term corrosion resistance
FBE components have excellent adhesion to steel, providing
excellent long-term corrosion resistance and protection for
pipelines operating at moderate temperatures.
If desired, low application temperature (LAT) FBE can be selected
as a primer to ensure low preheating conditions and long-term
integrity of high strength steels (X80 or higher)
In addition, 3LPE systems have excellent cathodic stripping
resistance, reducing the life cycle cost of cathodic protection
