3LPE Coating Pipe Production Line with 3-Layer Polyethylene Coating for Steel Pipe Anti-Corrosion (Pipe dia. 57-3400mm, CE, ISO, RoHS Certified)
Fusion-bonded Epoxy Coating Production Line Steel Pipe Anti-Corrosion Coating Equipment
Our Internal Anti-Corrosion Coating Line Pipe with 3PE and 2PE systems is designed for optimal protection of steel pipes used in harsh environments. The advanced 3-layer polyethylene (3PE) coating provides superior corrosion resistance, while the 2-layer polyethylene (2PE) coating ensures durability and reliability. Ideal for oil, gas, and water pipeline applications, this solution guarantees long-lasting performance and reduced maintenance costs, offering excellent protection against external and internal corrosion.
The pipe coating line meets the requirements of producing the steel pipe with coating which meets international standards DIN30670-1991,CAN/ Z245.21-2010,ISO21809-1-2009 SY/T 0413-2002, GB/T23257-2009,GOST 9.602-2016, GOST R 51164-98, GOST31448, GOST31445
The coating line mainly consists of the following units:
-steel pipe conveyor system
-shot/sand blasting system
-dust collector system
-pipe induction heating system
-epoxy powder spraying system
-PE&Adhesive coating system
-water cooling system
-pipe end cutting system
-hydraulic and pneumatic system
-testing system
-electronic control system
Technological process of 3LPE coating:
Pipe uploading→Shot blasting→Medium frequency induction heating→Epoxy powder spraying→Adhesive and polyethylene coating→Water cooling→Pipe end cutting back→Bevelling→Pipe unloading
The line can be customized to fit individual layout and application.

Pipe usage
3 layer PE anti-corrosion coating consist of first FBE coating, middle adhesive layer, and outer polyethylene layer.
The three-layer polyethylene anti-corrosion coating utilizes cutting-edge technology as the outer protective layer for buried pipelines. It is commonly used to protect gas and oil transmission lines, urban gas systems, water supply pipes, and other fluid transport pipelines. The 3PE coating enhances the mechanical strength of the pipeline, offering exceptional electrical resistance, waterproofing, wear resistance, and anti-aging capabilities
