What are the differences between plastic-coated steel pipes and coated steel pipes

both plastic-coated steel pipes and coated steel pipes are coated steel pipes, but their coating methods are different. plastic-coated steel pipes are coated with molten plastic on the surface of steel pipes to form a uniform plastic coating. this coating has good corrosion resistance and wear resistance and can protect the steel pipe from the erosion of the external environment.

coating steel pipe is brushing paint on the surface of the steel pipe to form a thin film coating. this coating has good anti-corrosion properties, but compared with plastic-coated steel pipes, its wear resistance and durability are poor.

therefore, plastic-coated steel pipes are suitable for occasions that require long-term use and high durability requirements, such as pipelines for transporting liquids or gases such as chemicals, oil, and natural gas; occasions, such as buildings, bridges, roads, and other fields.
