PE mining pipe special raw material not only has excellent long-term compressive strength, but also has excellent resistance to slow stress crack growth and fast stress propagation. HE3490-LS is black PE100 pipe special material, it also has excellent anti-sagging performance. In addition to outstanding antistatic and flame retardant properties, this pipe also has the advantages of high strength, good processing performance, good environmental adaptability, excellent stress cracking resistance and good creep resistance.
1. Strong Corrosion Resistance. The wear resistance of HDPE pipe is stronger than ordinary steel pipe,it is about 4 times than normal steel.
2. No-scale, small frictional resistance and low energy consumption.
3. Light weight, the weight of HDPE pipe is only about 1/5 of the ordinary steel pipe And HDPE pipe can be cut and welded at will. It is convenient to remove, install and repair.
1.Delivering powder and coal ash in thermal power plant.
2. Delivering mine tailings and slurry, metallurgical mines in the mining industry.
3. Delivering pulverized coal and coal-water slurry of coal preparation plant in the coal industry.
4. Delivering mud and corrosive media with slag in the chemical industry.
5. Delivering crude oil and petroleum.
6. Delivering sand \mud slurry for dredger in dredging projects or sand suction projects, and also for seawater treatment projects.
