Structure and composition
- 2pe anticorrosion (two-layer polyethylene) steel pipe two-layer PE anticorrosion structure, the first layer of adhesive (AD), the second layer of polyethylene (PE), the two materials into one.
- 3pe anticorrosion steel pipe refers to the 3-layer structure polyolefin coating (MAPEC) external anticorrosion steel pipe, 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, the actual operation of the three materials will be mixed and fused together, after processing to make it and the steel pipe firmly combined to form an excellent anticorrosion layer, its The processing method is generally divided into two types: winding type and round mold coating type.

Application Scenario
- 3PE anti-corrosion steel pipe: commonly used in large-scale infrastructure, such as large-scale pipeline network and marine engineering.
- 2PE anti-corrosion pipe: more suitable for underground municipal facilities, water supply and drainage networks and industrial wastewater treatment.
Maintenance and Cost
- 3PE anti-corrosion pipe: although the initial investment is higher, it may be more economical in the long run due to its excellent anti-corrosion performance and long service life.
- 2PE anti-corrosion steel pipe: lower installation and maintenance costs, suitable for projects with limited budgets.
