2PE coated pipe:
Bottom layer: usually an epoxy or adhesive layer that binds closely to the surface of the steel pipe and provides strong adhesion.
Surface layer: polyethylene layer, with good corrosion resistance, wear resistance and aging resistance.
3PE coated pipe:
Bottom layer: epoxy or adhesive layer.
Middle layer: usually copolymer adhesive layer, used to enhance the bond strength between the bottom layer and the surface layer.
Surface layer: Polyethylene layer, similar to the surface layer of 2PE, but may have a thicker coating and higher anti-corrosion properties.
Excellent anti-corrosion performance: with excellent corrosion resistance, it can effectively resist the erosion of soil, moisture, chemical substances and other external environment.
Good mechanical properties: while maintaining the original mechanical properties of the steel pipe, it also increases the wear resistance and impact resistance of the coating.
Long service life: Thanks to the protection of the coating, the service life of the steel pipe is significantly extended, reducing the frequency of replacement and repair.
Convenient construction: can use welding, thread connection and other ways to connect, the construction is simple and fast.
Environmental protection and energy saving: the coating material is non-toxic and harmless, meeting the requirements of environmental protection; At the same time, its use reduces energy consumption and emissions due to corrosion.
