What is a 3LPE pipe coating line?
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, and water supply pipelines.
3LPE pipe coating line 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.
3 Layers Polyethylene
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
Advantage of 3LPE Pipe Coating Line
- 3LPE anti-corrosion steel pipe has extremely high sealing performance, and long-term operation can greatly save energy, reduce costs, and protect the environment.
- Strong corrosion resistance, simple and quick construction, and a service life of 30-50 years.
- It also has good corrosion resistance and impact resistance under low-temperature conditions, and PE has low water absorption.
- At the same time, it has high epoxy strength, low water absorption of PE good softness of hot melt adhesive, etc., and has high anti-corrosion reliability. This anti-corrosion is characterized by a simple production process, good anti-corrosion effect, and low price. The anti-corrosion method generally recognized by the industry is three-layer polyethylene (3PE) steel pipe anti-corrosion for oil and natural gas, and two-layer polyethylene (2PE) steel pipe anti-corrosion
