3PE coating pipes

3PE coating 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.

ADVANTAGES OF THE THREE-LAYER COATING SYSTEM
  • Excellent corrosion resistance.
  • When exposed to either acid or alkaline media, an extended lifetime in highly corrosive soils is assured.
  • Strong steel adhesion: 20 times more adhesive than traditional plastic tape systems.
  • Excellent cathodic disbondment test results.
  • Excellent mechanical resistance.

High dielectric resistance : Superior bending ability for pipe laying applications

High impermeability: Both the high-density polyethylene and polypropylene have low water permeation characteristics that allow improved isolation from the surrounding sea water compared to other coating systems

3PE anticorrosive steel pipe characteristics:
  • very high tightness,which can greatly save energy, reduce costs, protect the environment in long-term operation.
  • strong corrosion resistance, the construction side simply speed, the service life can be up to 30-50 years.
  • with good resistance to corrosion and impact resistance, low water absorption, the PE (less than 0.01%) at low temperatures.
  • high strength epoxy, PE absorbent and hot melt adhesive softness, etc., have high corrosion reliability.
