Steel Pipe 3LPE FBE Anti-corrosion Coating Line For Oil Gas Pipeline Using Epoxy Powder PE Adhesive

Steel Pipe 3LPE FBE Anti-corrosion Coating Line For Oil Gas Pipeline Using Epoxy Powder PE Adhesive

The Steel Pipe Three-Layer Polyethylene (3LPE) Coating Line is a complete anti-corrosion solution for steel pipes, widely applied in engineering construction across the oil & gas industry and water transportation sectors.

The line supports multiple coating systems to meet varied project requirements:

• FBE (Fusion-Bonded Epoxy) powder coating
• Two-layer extruded polyethylene coating (2LPE)
• Two-layer polypropylene coating (2LPP)
• Three-layer extruded polyethylene coating (3LPE)

All coated pipes are produced to international standards, including DIN 30670-1991, CAN/CSA Z245.21-2010, ISO 21809-1-2009, SY/T 0413-2002, GB/T 23257-2009, GOST 9.602-2016, and GOST R 51164-98.

Key System Components
