  Pipe has three layer PE antisepsis structure: the first layer with epoxy powder (FBE> 100um), the second layer with adhesive (AD), 170 ~ 250um, the third layer with polyethylene (PE) 2.5 ~ 3.7mm. integration of them and solid steel pipe make form a good coating. Diameter range 60mm-1420mm, wall thickness 2.5-18mm, which is a good anti-corrosion method, generally can improve the service life of 50 years, not only extended the replacement cycle of the underground plumbing, and significant cost savings for the provides a strong role in nation-building. 3PE anti-corrosion is the most commonly used method of anti-corrosion, in addition to 2PE, 2PP, 3PP, their manufacturing process is similar to but different raw materials, this anti-corrosion characteristics of the simple fabrication process, the preservative effect, inexpensive pipe manufacturing industry generally agree that corrosion

  3PE anticorrosive steel pipe characteristics:

  1,very high tightness,which can greatly save energy, reduce costs, protect the environment in long-term operation.

  2, strong corrosion resistance, the construction side simply speed, the service life can be up to 30-50 years.

  3, with good resistance to corrosion and impact resistance, low water absorption, the PE (less than 0.01%) at low temperatures.

  4, high strength epoxy, PE absorbent and hot melt adhesive softness, etc., have high corrosion reliability.
