3PE and epoxy coating DIN 30670 steel pipe API 5L Seamless/ERW/LSAW   
 
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.
 
Usage: 
Oil and gas transportation pipeline, Water and other fluid pipeline,  Mineral slurry pipeline
