In long distance conveyance of crude oil, natural gas or refined oil, the pipeline usually need to be buried underground. When steel pipes or pipe fittings are in contact with soil and waters, we must consider its external anti-corrosion performance to ensure a durable lifespan of the pipeline.

The three layers Polyethylene(3PE/3LPE) external coating perfectly solves this problem. It consists of a high performance fusion bonded epoxy(FBE) layer, an adhesive layer and an outer layer of high density polyethylene. The three layers external coating has excellent resistance to abrasion, wear, acid, alkali and cathodic disbonding, etc. It is the preferred choice for transmission of oil and gas around the world. It can withstand varied temperatures and enviroments ranging from dessert dry lands to deep underwater regions. 3lpe coated steel pipe are uesd for transportation of drinking water. Oil and gas and other fluids. The 3LPE coated pipes can be used in the high temperatures as high as 60℃ to 80℃.

Features of 3LPE coated pipes

1. Excellent chemical and corrosion resistance preventing steel pipe from any damages.

2. Resistance to cathodic disbondmant.

3. The external layer of Polyethylene prevents any physical damage to either the pipes or the Fusion Bonded Epoxy during handling.

4. The 3LPE coated pipes have high performance characteristics and an extend life cycle.
