3PE mainly meaning every pipeline has three PE layer??The first layer is FBE??FBE??80um????The second layer is AD??170??250um??,The third layer is PE(1.8??3.7mm????Three kinds of material mixed together one organic whole, become solid combination with steel pipe forming excellent anti-corrosion layer.
2PE mainly say every pipeline has two layer of PE:The first layer is AD,the second is PE,two material mixed together one organic whole,thickness of every layer is same as 3PE.3PE produce process as follows:
