O-type Extrusion Type 3PE coated anti-corrosion production line (50-325mm）

O-type Extrusion Type 3PE coated anti-corrosion production line (50-325mm)

3LPE (Three-Layer Polyethylene) coated steel pipes consist of a multi-layered structure designed for superior corrosion resistance and durability.
Technological processes:

Upload pipes→pipes screw conveyor→rust removal→intermediate frequency heating→Epoxy powder coating→outer layer adhesive polyethylene coating→cooling spray→pipes screw conveyor→grinding pipe ends→unload pipes

This three-layer coating is widely recognized as one of the most effective anti-corrosion systems for buried steel pipelines.

Key Features of 3PE Anti-Corrosion Coated Steel Pipe Production Line
