HDPE double wall corrugated pipe   HDPE corrugated pipe
Material:HDPE,PVC,UPVC
Use,drainage,sewage,etc
Standard: GB/T 19472.1-2004
ISO9001:2008   HDPE double wall corrugated pipe    Advantage        Economic: with low cost than other same specifications plastic pipes, light weight, transportation, construction, management and maintenance of provinces expenses is convenient, large diameter, ring high stiffness.    Excellent corrosion resistance: won't be sewage and waste water and chemical corrosion and won't be soil rot in material and corrosion, also won't be plant root destruction.   Ageing resistance: pipe is commonly black and can withstand piled up and construction process for sunlight straight bask in.   Wear-resisting superior performance: than steel tube, iron pipes, cement tube wear resistance.    Drain liquidity superior: tube wall flow resistance small, drainage speed, the post-coiling water ability strong, large flow.   HDPE double wall corrugated pipe  Application      1.Civil engineering      2.agricultural irrigation      3.conveying system for sewage plant      4.pre buried piping under highway      5.Ventilation piping for chemical industry and mine      6.power telecommunication cable conduit      7.bridge construction    Specification:
