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.

3lpe Coating And FBE Internal Coating Machinery For Steel Spiral Pipes Easy To Install

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

Technological processes:
Upload pipes→pipes screw conveyor→rust removal of intermediate frequency heating→Epoxy powder coating→outer layer soli quid & polyethylene coating→cooling spray→pipes screw conveyor→grinding pipes, send→unload pipes

Advantage:

As the used customer evaluation, the use of Huastar technology of bending 3PE anti-corrosion equipment, to achieve fully automated production, improve production efficiency, promote the progress of technology in this field, to solve the problem of low precision bending 3PE anti-corrosion machining, small diameter range of machined pipe, automation, low degree of continuity, low level of industrialization, serious waste of raw materials, etc. Significantly improve the anticorrosion quality of pipe bends and overcome the key problems restricting the anticorrosion quality of pipelines.
