High Efficiency Steel Pipe Internal External Coating Machinery for
Making 3lpe 2PE 2PP Fbe Epoxy Pipe
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.

Application
The three-layer PE process, with the epoxy powder coating as bottom
layer, binding and bundling through polyethylene PE and adhesive,
is widely used in anticorrosion of steel pipes at home and abroad,
and applied to the oil pipeline and gas pipeline, as well as to the
gas supply and water supply for civil use.
Three-Layer PE pipe Structure Diagram
The three-layer PE anticorrosion structure includes fusion bonded
epoxy-powder bottom layer, polymer adhesive middle layer and
polyethylene top layer. The epoxy powder is a kind of thermosetting
nontoxic coating, forming the high molecular weight cross-linking
structure coating after solidifying, featuring good chemical
anticorrosion and higher mechanical properties. The function of
epoxy powder bottom layer is to form continuous coating, providing
excellent adhension by agglutinate and solidifying the steel tube
surface with good chemical resistance and cathodic disbanding
resistance. The function of polymer adhesive is to agglutinate the
epoxy powder before gelation, and to agglutinate the polyethylene
top layer, which unites all three layers together.
