Introduction to 3PE/2PE corrosion-resistant steel pipes

3PE anti-corrosion steel pipe structure 3PE anti-corrosion steel pipes usually consist of three layers: The first layer of epoxy powder (FBE>100um); The second layer of adhesive (AD) is 170-250um; The third layer of polyethylene is 2.5-3.7mm; In practice, these three materials are mixed and integrated together, and after processing, they are firmly combined with the steel pipe to form an excellent anti-corrosion coating. Generally speaking, there are two processing methods: winding type and...
