The 3LPE coating for large-diameter water pipelines is a combination of thermosetting epoxy resin powder coating and polyethylene properties and processing technology. It cleverly combines the three-layer structure polyethylene coating and the sintered epoxy powder coating technology to provide underground coatings. It provides a solution for corrosion protection of steel pipes. Generally, the inner wall is coated with fused epoxy resin powder (FBE) and the outer wall is brushed 3lpe.
The 3LPE coating on the outer wall of the steel pipe cleverly combines the three-layer polyethylene coating with the fused epoxy powder coating technology, providing It provides a solution for the corrosion protection of buried steel pipes. The inner wall is anti-corrosion with fused epoxy resin powder (FBE), which solves the problem of lining the pipeline. The pipe has small roughness, smooth inner wall and excellent hydraulic performance. Through analysis of design examples, it can be concluded that compared with pipes of the same diameter, the loss of pipelines with inner wall sintered epoxy coating can be reduced by more than 30%; when transporting the same flow rate, the pipe diameter can be reduced by one level, and then Reduce costs and reduce energy consumption. It has become a main product of large-diameter water transmission pipelines widely used in the market. Large-diameter water conveyance 3LPE coated steel pipe (usually lined EP coated 3PE) is a combination of thermosetting epoxy resin powder coating and polyethylene properties and processing technology.
