CHAPTER 2:PRODUCT INTRODUCTION
HDPEdoublewallcorrugatedpipeisakind ofcorrugatedstructurepipewhichmadeof high-densitypolyethyleneandnecessaryadditives.Theinnerwallissmooth,andtheouter walliscorrugatedandtheyareholowandtightlyweldedringstructures.Itsadvantages includecorrosionresistance,and longservice life,lowflowfrictionresistanceandstable performance.
Advantages
1
Light weight:
The density of HDPE is 0 . 9 5 9 / { \mathsf {cm } } ^ { 3 } ,which is onlyone eighth of traditional cement tube, it's very convenient for construction.
Cold resistance:
PE material has good low temperature performanceand can be used safely in the temperature range of-40-40 degrees.
No leakage:
sealingringconnectionwithexcellent leakproofness.
串
Anti-settling:
HDPEdoublewall corrugated pipe has good flexibility,excellent resistance to foundation settlement,and has excellent engineering value.
Flexible:
HDPE double wall corrugated pipe is flexible;Itcanrelease theappliedload throughacertaindeformation.
Anti-UV:
The outerwall of HDPE double wall corrugated pipeisaddedwithacertaincompositionof carbonblack,whichhasexcellentresistance toultravioletradiation
Corrosion resistance: HDPEisachemically inert material that can risistthecorrosionofmostchemicalmedia.
四
Durable:
HDPEmaterialisawear-resistantmaterial, thewearresistanceis4timesthatofsteel pipe,and the service life is long.
a
Impact resistance:
PEmaterial has good impact resistanceand willnotbreakbrittlelywhen impacted by external force.
Non-toxic:
The HDPE material is hygienic and non-toxic, andthereisno toxicgasemissionwhen burning,no hidden danger of "white pollution".
