HDPE double wall corrugated drainage pipe hdpe corrugated pipe
HDPE double wall corrugated drainage 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 drainage pipe Application
- Civil engineering.
- agricultural irrigation.
- conveying system for sewage plant.
- pre buried piping under highway.
- Ventilation piping for chemical industry and mine.
- power telecommunication cable conduit.
- bridge construction.
