Compared with other pipes

1. Flow Comparison

HDPE high density PE double-wall corrugated pipe: The absolute roughness of inner wall is only 0.009mm,minimum friction resistance coefficients, and it wont be changed with time during the term of use. In graveity flow systerm, equal flow required, so the required inner dinemeter of PE double-wall corrugated pipe should be smaller than pipes in other materials. After caculation, it shows that if we want equal flow, the inner diameter of PE double-wall corrugated pipe is only 96% of stainless steel pipe, 87.7% of nodular cast iron pipe and 90.6% of cement pipe, which means we could save large amount of engineering material when use PE double-wall corrugated pipe.

Corrosion resistance


It has strong acid and alkali corrosion resistance, it wont be corroded in sea water, acid and alkali soil.


Better


No acide and alkali

Corrosion resistance, the serious will occur leakage and underground pollution  


Impact Resistance


Good impact resistance


It will have crack and risk of break under impact of hard things. Bad impact resistance.

Application property


Save mechanical expenses,easy connection, it has gurantee for construction quality in water(The minumum work temperature is -30),good application property, especially suitable for northern area

  

Connect by rubber plastic ring of bonding easier construction, but no guarantee for construction quality in winter(The minmum work temperature is 5


Heavu material, transportation and construction are not easy. Bad operating in manual connection

Economy

Hygienic property


Non-toxic, no pollution, well-known and best hydienic property


After the waster pipe burnt, it will release heavy metal smoke and pollute the environment


It has water leakage phenomenon, which will pollute environment
