corrosion resistance UHMW-PE tube for chemical industry
The introduction of HDPE pipe :
HDPE pipe is suitable for water quality fluid ,solid particles , powder,slurry,etc. It is widely used in various industries with high corrosion resistance, high wear resistance and self-lubricating absorbing shock . There are unique advantages in solid particles , powder ,slurry and gas delivery .
Features of the HDPE pipe :
1. Anti-abrasion
2. Water hammer resistance:HDPE pipes have strong enduring capability to the impacts from various sands,mud and slurries.
3. Corrosive resistance:With higher structure stability ,HDPE pipes are corrosive resistant to sea waters.No electro chemical corrosion,no need anti-corrosive coating.
4. Self-lubrication:The roughness of HDPE pipe is 0.00022mm.The pressure loss of HDPE pipe is 1/10 of steel pipes ,1/7 of nylon pipes.Over 20% of transfer efficiency will be increased.
5. Non-scaling:The internal wall is very smooth,preventing the fouling on the wall and no influence to the production efficiency.
6. Light weight:The density of HDPE pipe is only 1/8 of steel pipe.It is easy to move and install,especially suitable for the working sites at he lifting machines could not work.
7. Easy connection:flanges are available to connect the pipes,no need washers .The installation will be very easy and fast.
8. Anti-aging:the HDPE pipes will not be aging in 50 years under hot sunlight,and it could work over 100 years if buried underground.
9. Environment friendly: HDPE pipe is nontoxic,no bacteria,and no pollution to environment.
10. Low carbon:the discharge of carbon dioxide during HDPE pipe production is only 15% of steel pipe production.
Application fields of the HDPE pipe :
1 mine and metallurgy industry : coal , ore , nonferrous metal tailings, slurry and rock delivery
2 food industry , grain and flour transport
3 dredge , slurry and sand dredging
4 chemical industry : mud and corrosive medium with slag
5 water disposal
6 coal industry : pulverized coal waste and coal -water slurry
7 sea river engineering : sea water desalinization , dredging
8 oil and gas , petroleum transport
