UHMWPEパイプ

1、No Leakage

The traditional water supply and drainage pipelines like PCCP pipes, steel pipes, FRP pipes are connected by socket welding and sealed with rubber washers which results in serious leakage with an average leakage rate of 15~30%. Correspondingly, it increased energy consumption and maintenance cost. UHMWPE pipe with its extraordinary performance successfully solved this problem and is a great revolution for water supply and drainage projects.

2、Low Energy Consumption

Friction resistance coefficient of UHMWPE pipes is 0.009 while that of steel pipe is 0.013 and that of cement pipe is 0.15. With the same diameter, UHMWPE pipe can deliver more water than PCCP pipe and others. With the same flow rate, UHMWPE pipes can save 25% energy than other pipes.

3、Maintenance Free

With characteristics of corrosion resistance, low temperature resistance, non-scaling, no leakage, etc, UHMWPE pipe can work without extra anticorrosive coating, cleaning and maintenance which save more than 95% energy.

4、Corrosion Resistance

With high chemical stability, UHMWPE can resist corrosion of corrosive media like acid，alkali and salt and organic solvent. It can be applied in water supply at seabed and transmission of salt water and acid or alkali fluid.

5、Low Temperature Resistance

At the temperature of -70 ℃，UHMWPE pipe can work with normal mechanical performance. It is suitable for water supply and drainage in cold area.

6、Non-scaling

With smooth inner wall and roughness of 0.00022, UHMWPE pipe can work for a long time without scaling and breeding bacteria , while roughness of PCCP and steel pipe is 0.01-0.09 which is easy scaling and growing moss therefore influencing the water quality and doing harm to human health.

7、Environment Friendly

UHMWPE is authorized by the nation as material being environment friendly, non-toxic, harmless to human health. UHMWPE pipe is the best alternative for water supply pipe.

8、High Pressure Resistance

The compressive strength of UHMWPE pipe is 2 times to that of PE100 pipe and 2.5 times to that of PE80. UHMWPE pipes can withstand wide fluctuate of water pressure in the pipeline. Its ring stiffness is more than 8 KN/㎡ which can withstand high load for the pipeline underground.

9、High Flexibility

With high toughness and elongation of no less than 350%, the UHMWPE pipe and the connection site will not crack when crust settling which maximally ensure to supply water normally.

10、Impact Resistance

UHMWPE pipe has good impact resistance and can withstand impact of water hammer. There is no need to build anchor block at the turning site.
