Coated Pipeline---3PE Pipe
When we use pipeline to transfer natural gas or oil for long distance conveyance, we always need to burry the pipeline underground. When steel pipes or pipe fittings are in contact with soil and wet condition, we must consider its external anti-corrosion ability to ensure a longer lifespan of the pipe. The 3 layers Polyethylene(3PE/3LPE) external coating perfectly solves this problem. Its first level is a high performance fusion bonded epoxy(FBE) layer, then comes an adhesive layer, and finally is 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 3 layers for pipeline coating. First Layer: Fusion Bond Epoxy>100um consists of fusion bonded epoxy. This layer protection against corrosion and is fusion with the blasted steel surface. Second Layer :170~250um, is copolymer adhesive which has excellent chemical bonding to the internal layer a...
