3LPE Coating Line for Steel Pipes with FBE and Polyethylene

Product Description

The three-layer polyethylene (3LPE) process uses fusion-bonded epoxy (FBE) as the bottom layer, adhesive (AD) as the middle layer, and polyethylene (PE) as the outer layer. This structure provides superior corrosion protection for steel pipes, extending service life from 5-10 years to 50-100 years.
It is widely applied in oil and gas pipelines, as well as urban gas and water supply pipelines. The 3LPE coating offers high mechanical strength, excellent electrical insulation, and strong resistance to environmental degradation.
