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
Double-layer fused epoxy powder spraying method: the process has
low efficiency and poor effect, and also directly affects the
corrosion life of the pipeline, because the thickness of the
anti-corrosion layer is only 800μm, which is about 20% of the
thickness of the 3PE anti-corrosion layer. The double epoxy layer
has good scratch resistance but poor impact wear resistance, and it
is easy to damage the anticorrosive layer in the process of bending
pipe down the ditch and backfilling. The anticorrosive layer at the
end of the pipe is damaged due to transportation and lifting, and
the repair operation of the damaged double epoxy anticorrosive
layer is more complicated, and the anticorrosive layer can only
withstand 4Kv electrical spark leak detection voltage, and the heat
shrink sleeve repair is 15Kv, which is the weak point of the
pipeline external anticorrosion.

Advantage:
As the first (set) technical equipment and key core parts
manufacturing enterprises and product list in Shandong, 426-1220
bending pipe winding 3PE anti-corrosion production line, the
product belongs to the field of high-end equipment manufacturing,
in line with the national and Shandong Province industrial policy,
included in the strategic orientation of economic development. For
oil and gas transportation, gas transportation, water supply
transportation, sewage transportation, chemical transportation, the
market is huge, in line with industry-oriented demand. It has long
been integrated into the "Belt and Road" Initiative, and has been
accepted by Russia, Kazakhstan, Iran, the United Arab Emirates and
other countries along the line, and has produced a good brand
influence.
