What is 3LPE pipeline anticorrosion?
3LPE anti-corrosion steel pipe coating (three-layer polyethylene anti-corrosion coating) is a new type of anti-corrosion produced by ingeniously combining the European 2PE anti-corrosion coating and the epoxy powder anti-corrosion steel pipe coating (FBE) widely used in North America. Steel pipe coating. Widely used in oil pipelines, natural gas pipelines, heating pipelines, water supply pipelines.
3LPE anti-corrosion coating combines the high impermeability and high mechanical properties of epoxy resin and polyethylene materials. So far, it is the globally recognized pipeline anti-corrosion coating with the best use effect and the best performance, which is used in many projects.
The coating of 3LPE anti-corrosion steel pipe is that the bottom layer and the surface of the steel pipe are in contact with epoxy powder anti-corrosion coating, and the middle layer is a copolymerized adhesive with branched functional groups. The surface layer is high-density polyethylene anti-corrosion coating. In actual operation, the three materials are mixed and integrated, and after processing, they are firmly combined with the steel pipe to form an excellent anti-corrosion layer. Its processing methods are generally divided into two types: winding type and round mold wrapping type.
3LPE anti-corrosion steel pipe generally consists of three layers:
The first layer of epoxy powder (FBE>100um)
The second layer of adhesive (AD) 170 ~ 250um
The third layer of polyethylene (PE) 2.5 ~ 3.7mm
