Ipn8710 Epoxy Internal Coating Water Steel Pipe
API 3PE/3PP Coating Cold Drawn Carbon Steel Pipe
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.
3 PE anti corrosion is one of the main technology system at home and abroad at present, anticorrosion of buried pipeline. It has good corrosion resistance, low water absorption rate, high mechanical strength and performance, in recent years in the domestic underground water, gas, oil path pipe has been used more and more widely.
