3PE anti-corrosion refers to the three layers of PE pipe anticorrosion structure: the first layer of epoxy powder (FBE), the second layer of adhesive (AD), the third layer of polyethylene (PE) (polyethylene color is generally black, but also according to customer Require the production of blue / yellow and other colors). Where 2PE does not contain the first layer.
Three materials into one, and firmly combined with the formation of a good anti-corrosion coating, coating temperature up to 70 degrees.
Common implementation of standards: SY / T0413-2002, GB / T23257-2009, DIN30670 and so on.
Minimum layer thickness can refer to the corresponding standard.
3PE anti-corrosion process is as follows:
