Description:
A 3PE (Three-Layer Polyethylene) anti-corrosion coating production line is a process that involves applying three distinct layers of protective materials onto the surface of steel pipes. This advanced coating system is designed to significantly extend the service life of the pipes, often from a relatively short span of 5-10 years to an impressive 50-100 years or even longer.
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.
