3pe anti-corrosion steel pipe base material including seamless steel pipe, spiral steel pipe and straight seam steel pipe. Three-layer structure of the polyethylene (3PE) anti-corrosion coating with its good corrosion resistance, moisture resistance and mechanical properties, 3PE anti-corrosion steel pipe for a buried pipe life is critical, The same material of the pipeline, and some buried in the ground for decades without corrosion, and some years there have been leaked. It is because they use a different outer coating.
Corrosion protection of steel pipe wall
3PE corrosion generally consists of three layers of structure:
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 into one, after processing and steel pipe firmly combined to form an excellent coating. The processing methods are generally divided into two types of winding and round die.
