The 3LPE/3PE Coated Pipeline
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.
3LPE coated pipes consist of 3layers for pipeline coating.
Layer 1(FBE>100um consists of fusion bonded epoxy. This layer protection against corrosion and is fusion with the blasted steel surface.
Layer 2 (170～250um) is copolymer adhesive which has excellent chemical bonding to the inner layer and the top layer of polythylene
Layer 3 (2.5～3.7mm) is the layer of polyethylene used for protection against any physical damage of the pipes
This three layers, combined with steel pipe firmly, forming excellent anti corrosive coating, can use the range of pipe diameter range 25Φ~ 2420Φ.
