Steel Pipe Surface Cleaning & 3lpe/Fbe Anti-Corrosion Coating Line
The Steel Pipe Internal & External 2LPE / 3LPE / FBE Liquid & Powder Epoxy Coating Line is designed for high-performance anti-corrosion treatment of steel pipes. It is widely applied in various infrastructure projects, particularly in oil and gas transmission as well as water pipeline systems.
This coating system supports multiple anti-corrosion technologies, including Fusion Bonded Epoxy (FBE) powder coating, two-layer extruded polyethylene (2LPE), two-layer polypropylene (2LPP), and three-layer extruded polyethylene (3LPE) coating solutions.
The production line is engineered to manufacture coated steel pipes in full compliance with major international standards, including DIN 30670:1991, CAN Z245.21-2010, ISO 21809-1:2009, SY/T 0413-2002, GB/T 23257-2009, GOST 9.602-2016, and GOST R 51164-98, ensuring reliable quality and long-term corrosion protection performance.
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.
